Hu, Yao. "The Modeling, Analysis and Control of Resilient Manufacturing Enterprises." UKnowledge, 2013. http://uknowledge.uky.edu/ece_etds/15.
Full textAbstract:
The resilience of manufacturing enterprises is an important research topic, since disruptions have severe effects on the normal operation of manufacturing enterprises, especially as manufacturing supply chains become global. Although many case studies have been carried out to address resilience in organizations, a systematic method to model and analyze the resilience dynamics in manufacturing enterprises is not well developed. This study is intended to conduct research on quantitative analysis and control for resilience.
After reviewing the literature addressing resilience, a modeling framework is presented to characterize the resilience of a manufacturing enterprise responding to disruptive events, which includes inventory ow between enterprise nodes, different costs, resource, demand, etc. Each node within the network is represented as a dynamic model with associated costs of production and inventory. This mathematical model is the foundation of quantitative analysis and control. With this model, an optimal control problem is formulated, by which the control can be solved to achieve minimum cost.
Several different types of systems are defined and analyzed in this work. We develop the approach of aggregation to simplify the network structures. The study is mainly focused on two categories of network systems: serial network systems and assembly tree network systems. The analysis on these two categories covers two conditions: in discrete time domain without considering capacities, and in continuous time domain with considering capacities. The methods to determining optimal operations are developed under different conditions. In the serial network systems analysis, a practical case study is introduced to show the corresponding method developed. Finally, the problems are discussed for future research.
Based on the results of these analyses, we present optimal control policies for resilience. Our method can support the analysis of the impact of disruptions, and the development of control strategies that reduce the impact of the disruption.

Jonsson, Fredrik. "Product Related Environmental Work in Small and Medium Sized Enterprises in Thailand, Developing and Manufacturing Electrical and Electronic Products." Thesis, Linköping University, Department of Management and Engineering, 2007. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-8828.
Full textAbstract:
Small and Medium Sized Enterprises (SMEs) in Thailand that develop and manufacture electrical and electronic products are among other SMEs in the world meeting increasingly stringent legal and customer requirements related to environmental issues. Obstacles for the SMEs around the world to meet these requirements are almost the same in form of lack of knowledge, budget and resources. The differences between SMEs in Thailand and SMEs in the EU, Japan or even Korea are that these countries have been developed the eco-design concept and SMEs have been involved in eco-design activities for many years. This process and activities are new both for the SMEs and for the supporting institutes and organisations in Thailand. Thailand has just started to build up the infrastructure to support the SMEs to implement the eco-design concept and to work more with product related environmental issues. The focus right now for the SMEs in this research is to comply with the EU Directives, RoHS and WEEE, and this is where the main investments are made, e.g. in order to be able to export to the demanding EU market.
This research is investigating what kind of environment demands that SMEs in Thailand that develop and manufacture electrical and electronic products have on their products, how they handle these requirements and also what obstacles there are for implementing a more product related environmental concept, also known as eco-design, Design for the Environment (DfE), Green Design or Environmentally Oriented Design. A research in form of interviews and factory visits has been done with five different SMEs in Thailand. These five SMEs have also participated in the first official eco-design projects in Thailand with funding from the government in Thailand and also some from the EU. Interviews have been conducted with involved parties in these project such as institutes and experts provided by Universities. These interviews were made in order to get their opinion and experience about the present situation for SMEs in Thailand that develop and manufacture electrical and electronic products to work with product related green issues.
The research shows that these companies have the possibilities and conditions to work further on with the eco-design concept in the future. Their participation in the eco-design projects has been a good experience and there is evidence of strong support from the management and owners, environmental awareness, pro-active work and motivation among the companies. The obstacles are as mentioned above concerning lack of resources, knowledge and experience of how these environmental demands and requirements will affect the product development process. This lack of experience depends mostly on the fact that these eco-design projects are the first projects in this field for the companies. These five companies have now built up a fundamental knowledge but are still in need of further support. The communication between the SMEs and supporting parties are important and also one factor these five companies think is functioning well.

Visser, Charl. "An investigation of the factors influencing the sustainability of small- and medium-scale electrical contracting enterprises (SMECEs) in the Cape Peninsula." Thesis, University of Cape Town, 2004. http://hdl.handle.net/11427/6735.
Full textAbstract:
This study focuses on small- to medium-scale electrical enterprises (SMECEs) in the Cape Peninsula, and specifically on electrical contractors with fewer than 25 employees. The objectives of this study are threefold: Firstly, the study reviews the position of current SMECEs, their economic contribution to the economy, their origin and establishment, the lifespan of the business, as well as the level of education of the individuals involved in the business. Secondly, it determines the constraints and limitations that may lead to the failure of these businesses. And, thirdly, it identifies the factors that may enable SMECEs to become sustainable or successful enterprises. A two-phased research method was used to collect information from owners of electrical contracting firms. This method involved the use of a pilot survey questionnaire and a main survey questionnaire. The pilot and main questionnaires were used to obtain data pertaining to the electrical contracting industry and owners of such firms. More specifically, this data includes information on the background of the company and its owner, the establishment of the business and its employment structure, as well as its work history, current operations and future objectives. It also looked at the constraints and limitations faced by these SMECEs, and identified specific factors that may enhance their sustainability. These questionnaires revealed that the constraining factors could be placed into two main categories, viz. management and labour. Management problems, for instance, included poor cash flow because of slow payment by clients, a lack of management skills on the part of business owners, and an inability to calculate project costs accurately. Labour problems, on the other hand, included an unreliable work force with no proper or effective work ethic, a lack of skilled and trained labour, and a work force that was inadequately skilled as either electricians or assistants. Among the factors that are necessary to ensure the success and sustainability of SMECEs, were the following: Business owners need to deal personally with problems and constraints and must learn how to avoid them. They must improve their management and planning ability, and must be able to understand the market. Their business must offer good workmanship and quality of service, and they must be able to complete their projects successfully. A reliable skilled work force is imperative, as are marketing skills and the ability to ensure the controlled growth of the firm. The following recommendations are made to owners of SMECEs: In order for their business to be successful and sustainable, they need to identify training courses that can assist their current contracted labour force. Business owners themselves also need to attend tendering and cost-control courses to improve the running and management of their business. They need to support the education and training of their work force and to employ skilled workers. Furthermore, they must ensure that the scope of the electrical contract is explained to the work force and that there is a written contract from the client, setting out the conditions of payment, in order to prevent late payment and thus cash flow problems.

Yan, Xin. "Leadership and internal guanxi in Chinese electric motor enterprises." Thesis, Abertay University, 2016. https://rke.abertay.ac.uk/en/studentTheses/4b84834f-1cbe-47da-8dfc-9c14b765fdd6.
Full textAbstract:
This research explores the nature of guanxi inside Chinese enterprises and considers the implications for leadership at a time when Western leadership models are growing in dominance, and Eastern cultural norms are still in existence. The literature on guanxi is extensive, but the lack of its application inside organizations, and, in this case, in the leadership function is sparse. The research questions include whether guanxi is applied internally to the organization and, if it is, how does this influence leadership behaviour? The research adopts a pragmatist, social constructivist position, and uses a mixed method approach to investigate the interaction between leadership behaviour and guanxi: the internal guanxi. The researcher is an employee of ABLE Electric Motor Group, a large and successful private sector enterprise in the rapidly growing and transforming Chinese economy. Drawing on the special and unique position in the organisation and existing experience, the researcher uses multiple employee case studies, involving 34 in-depth interviews with senior leaders across ABLE, and surveys the Chinese electric motor sector using a questionnaire collected from 337 respondents. The research developed a conceptual model, creating links between Chinese leadership characteristics and guanxi characteristics, and these are used to focus on the collection and analysis of themes. These themes correspond to seven propositions arising from the initial desk research, the on-going participant observation and a pilot study. These are then explored further through the findings and discussion. The findings suggest that internal guanxi is operating and that it extends beyond the boundaries of the company. However, globalisation and transformation in the Chinese market are changing the nature of the relationship between leadership and guanxi and producing mixed results. Private sector businesses benefit from the leadership–guanxi dynamic, while foreign and state firms are deriving fewer benefits. The research identifies three models of the internal guanxi–leadership relationship: (i) internal, (ii) inter-firm and (iii) inter-regulatory hybrid, providing examples of prominence and behaviours. Leadership approaches that ignore the role of guanxi limit the potential of the firm, which impacts on innovation, the recruitment, and retention of staff. Foreign and state-owned firms are less likely to resolve problems through relationships and typically apply more formal structures. This research has implications for culturally different companies entering this market and those transforming companies that need to maintain harmony in times of revolutionary change.

Ekstedt, Mathias. "Enterprise architecture for IT management : a CIO decision making perspective on the electrical power industry." Doctoral thesis, KTH, Electrical Systems, 2004. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-36.
Full textAbstract:
Within the electric power industry, the average company's enterprise system - i.e. the overall system of IT related entities - is today highly complex. Technically, large organizations posses hundreds or thousands of extensively interconnected and heterogeneous single IT systems performing tasks that varies from enterprise resource planning to real-time control and monitoring of industrial processes. Moreover are these systems storing a wide variety of sometimes redundant data, and typically they are deployed on several different platforms. IT does, however, not execute in splendid isolation. Organizationally, the enterprise system embraces business processes and business units using as well as maintaining and acquiring the IT systems. The interplay between the organization and the IT systems are further determined by for instance business goals, ownership and governance structures, strategies, individual system users, documentation, and cost.
Lately, Enterprise Architecture (EA) has evolved with the mission to take a holistic approach to managing the above depicted enterprise system. The discipline's presumption is that architectural models are the key to succeed in understanding and administrating enterprise systems. Compared to many other engineering disciplines, EA is quite immature in many respects. This thesis identifies and elaborates on some important aspects that to date have been overlooked to a large extent. Firstly, the lack of explicit purpose for architectural models is identified. The thesis argues that the concerns of a company's Chief Information Officer (CIO) should guide the rationale behind the development of EA models. In particular, distribution of IT related information and knowledge throughout the organization is emphasized as an important concern uncared for. Secondly, the lack of architectural theory is recognized. The thesis provides examples of how theory, or analysis procedures, could be incorporated into the Enterprise Architecture approach and hereby concretely drive the development of the architectural models. Due to the nature of enterprise systems, EA theories inevitable will be of an indicative character. Finally, in relation to the models as such, three aspects are highlighted. Firstly, the cost of collecting information from the organization to populate models is routinely neglected by the EA community. This expense should be evaluated in relation to the utility of analyses that the information can provide in terms of better informed decision making by the CIO. Secondly, models (and meta-models) must be kept consistent. And thirdly, the design of models is restricted by the limited mental capabilities of the minds of the model users. CIO concerns must consequently be easy to extract from the Enterprise Architecture models.

Full textAbstract:
In addition to storing 70-75% of their data and business logic in legacy mainframe systems, global corporations have countless custom applications and off-the-shelf ERP products residing within their networks. Increasing competition and shrinking budgets have left managers scouring for innovative, cost-effective methods to maximize the potential of these enormous sunk costs. There is, as a result, an overwhelming need to not only web enable these existing legacy assets in order to quickly and cost-effectively deliver data to both customers and business partners alike, but also to amalgamate these disparate systems into a unified, homogeneous, real-time enterprise. Integration efforts to date, focused predominantly on the development of proprietary point-to-point adapters, have unfortunately proven to be a daunting task with countless failed projects and losses in the millions. The advent of XML web services does, however, have the potential to revolutionize existing integration strategies; the cost savings and ease of implementation associated with wrapping virtually all systems, past, present and future, with standardized, code-independent, data-centric interfaces is truly astounding. As the future success of this platform is, however, strictly dependent upon the interoperability of its endpoints, we have proposed several fundamental amendments to the existing flawed WSDL specification. A generic reference architecture, leveraging both this improved web services model as well as established component middleware technologies, is then proposed for the web enablement of legacy assets on an enterprise scale. In order to ensure the adoption of this methodology, a toolkit designed to automate the transformation has also been devised. This new paradigm will not only allow information to flow freely from deep within the enterprise, but will ultimately serve as the cornerstone of a new generation of enterprise integration solutions.

The Supply Planning Operations team, in a large manufacturing firm, faced a future where their complexity of scope was increasing without an increase in resource levels. As an effort to improve both efficiency and effectively within the organization, they chose to adopt Lean Thinking as a method to streamline and simplify activities, connections and flows. Lean Thinking, while often viewed as a set of tools (value stream mapping, andon cords, kanbans, and others), involves the harmony between principles, culture and the appropriate application of tools. SPO has taken an approach focused on culture and deep understanding of Lean Principles before deploying the tools of Lean. It was important to examine why artifacts succeeded or failed in influencing cultural change. One common theme for successful artifacts was their portability. With a geographically diverse team, it was important that any artifact could be transported electronically. Although not all the actions have been successful in influencing the organization's culture, many actions have had a profound impact. Seeing members of the organization write about their personal experiences is just one example of how Lean Thinking has been adopted. By committing to "Rules before Tools," the group embarked upon a journey to change culture. This thesis used an Enacted Systems Analysis to identify Artifacts, Habits of Thought and Habits of Action. Several organizational barriers emerged along with possible levers to promote change. Even though the revolution is only in its infancy, SPO appears to be on a sustainable path toward a Lean Thinking transformation.

Full textAbstract:
Nowadays, there is a belief that organizations should keep improving different aspects of theirenterprise to remain competitive in their business segment. For this purpose, it is required to understand the current state of the enterprise, analyze and evaluate it to be able to figure out suitable change measures. To perform such a process in a systematic and structured way, receiving support from powerful tools is inevitable. Enterprise Modeling is a field that can support improvement processes by developing models to show different aspects of an enterprise. An Enterprise Modeling Method is an important support for the Enterprise Modeling. A method is comprised of different conceptual parts: Perspective, Framework, Method Component (which itself contains Procedure, Notation and Concepts), and Cooperation Principles. In an ideal modeling process, both the process and the results are of high quality. One dimension of quality which is in focus in this thesis is efficiency. The issue of efficiency evaluation in Enterprise Modeling still seems to be a rather unexploited research area. The thesis investigates three aspects of Enterprise Modeling Methods: what is the meaning of efficiency in this context, how can efficiency be evaluated and in what phases of a modeling process could efficiency be evaluated. The contribution of the thesis is an approach for evaluation of efficiency in Enterprise Modeling Methods based also on several case studies. The evaluation approach is constituted by efficiency criteria that should be met by (different parts of) a method. While a subset of these criteria always need to be fulfilled in a congruent way, fulfillment of the rest of the criteria depends on the application case. To help the user in initial evaluation of a method, a structure of driving questions is presented.

Full textAbstract:
With the growing popularity of Bring Your Own Device (BYOD), modern enterprise Wireless Local Area Networks (WLANs) deployments always consist of multiple Access Points (APs) to meet the fast-increasing demand for wireless access. In order to avoid network congestion which leads to issues such as suboptimal Quality of Service (QoS) and degraded user Quality of Experience (QoE), intelligent network traffic control is needed. Software Defined Networking (SDN) is an emerging architecture and intensively discussed as one of the most promising technologies to simplify network management and service development. In the SDN architecture, network management is directly programmable because it is decoupled from forwarding layer. Leveraging SDN to the existing enterprise WLANs framework, network services can be flexibly implemented to support intelligent network traffic control. This thesis studies the architecture of software-defined enterprise WLANs and how to improve network traffic control from a client-side and an AP-side perspective. By extending an existing software-defined enterprise WLANs framework, two adaptive algorithms are proposed to provide client-based mobility management and load balancing. Custom protocol messages and AP load metric are introduced to enable the proposed adaptive algorithms. Moreover, a software-defined enterprise WLAN system is designed and implemented on a testbed. A load-aware automatic channel switching algorithm and a QoS-aware bandwidth control algorithm are proposed to achieve AP-based network traffic control. Experimental results from the testbed show that the designed system and algorithms significantly improve the performance of traffic control in enterprise WLANs in terms of network throughput, packet loss rate, transmission delay and jitter.

Full textAbstract:
Electronic message transfer is the key element in enterprise application integration (EAI) and the privacy of data transferred must be protected by the systems involved in the message transfer from origin to the destination. The recent data privacy regulation such as GDPR (General Data Protection Regulation) has enforced the organizations to ensure the privacy of the personal data handled with obligations to provide visibility and control over to the data owner. Privacy concerns with relevant to sensitive data embedded and transferred through business-to-business (B2B) middleware platforms in enterprise architecture are mostly at risk with the legacy nature of the products and the complexity of system integrations. This poses a great threat and challenge to organizations processing sensitive data over the interconnected systems in complying with regulatory requirements. This research proposes a solution design to address the data privacy issues related to personal data handled in an enterprise application integration framework. Where electronic messages used to transfer personally identifiable information (PII). The proposal consisting of a design called “Safety Locker” to issue unique tokens related to encrypted PII elements stored in a persistence data storage based on Apache Ignite. While adding REST API interfaces to access the application functionality such as tokenization, de-tokenization, token management and accessing audit logs. The safety locker can run as a standalone application allowing clients to access its functionality remotely utilizing hypertext transfer protocol (HTTP). The design allows the data controllers to ensure the privacy of PII by embedding tokens generated from the application within the electronic messages transferred through interconnected systems. The solution design is evaluated through a proof of concept implementation, which can be adapted, enhanced to apply in EAI implementations.

While a significant amount of literature exists that discuss platform strategies used by general IT vendors, less of it has to do with corporate networking technology vendors specifically. However, many of the same strategic principles that are used to analyze general IT vendors can also be used to analyze networking vendors. This paper extends the platform model that was developed by Michael Cusumano and Annabel Gawer to networking vendors, outlining the unique strategic aspects that the networking market possesses. The paper then reviews the strategy of the first dominant corporate datacom vendor, IBM, how it achieved its dominance, and how it lost it. The paper then discusses the strategies of various vendors who attempted to replace IBM as the dominant networking platform vendor and how they failed to do so. Finally, the paper discusses Cisco Systems, a vendor who did manage to achieve a level of dominance that parallels IBM's, and how that company has utilized its strategy to achieve and maintain its current dominance. Finally, Cisco's current strategic challenges are discussed. The impact of the strategies of the various vendors on the evolution of corporate networking is also discussed.

Full textAbstract:
Security is one of the key concerns in the domain of Information Technology systems. Maintaining the confidentiality, integrity and availability of such systems, mandates a rigorous prior analysis of the security risks that confront these systems. In order to analyze, mitigate and recover from these risks a metrics based methodology is essential in prioritizing the response strategies to these risks and also this approach is required for resource allocation schedules to mitigate such risks. In addition to that the Enterprise Objectives must be focally integrated in the definition, impact calculation and prioritization stages of this analysis to come up with metrics that are useful both for the technical and managerial communities within an organization. Also this inclusion will act as a preliminary filter to overcome the real life scalability issues inherent with such threat modeling efforts. Within this study an attack tree based approach will be utilized to offer an IT Security Risk Evaluation Method and Metric called TEOREM (Tree based Enterprise Objectives Risk Evaluation Method and Metric) that integrates the Enterprise Objectives with the Information Asset vulnerability analysis within an organization. Applicability of the method has been analyzed within a real life setting and the findings are discussed as well within this study.

Full textAbstract:
Most large enterprises are facing numerous challenges concerning their information systems, IS, and information and communication technology, ICT. Today, many enterprises employ a considerable number of applications that often have redundant functionality. There is also a large diversification in the ICT products and technologies employed. Further, integration costs are a major issue in almost all acquisition projects and many enterprises experience a lack of data quality and information security. The list of IS/ICT management challenges can be made much longer. At most enterprises, IS/ICT decisions are made by autonomous business units. In order to change the situation described above and build a more cost-effective IS/ICT environment, all business units need to make consistent IS/ICT decisions. Distributed and consistent decisions can only be made if the decision maker knows which decisions to make and why he/she needs to make them. The latter can be described by the target architecture for the whole enterprise IS/ICT, the information needed to conduct the business and its relationship to the business processes and business organization together with the benefits that the target architecture provides to the business. Which decisions to make are formulated into architectural principles, i.e. rules that express how your enterprise needs to design and deploy IS/ICT. The present thesis is a composite thesis including eight papers. The first four papers describe the reference model for IS/ICT management responsibilities that is one of the outcomes of the present research. Two different surveys have been performed in order to find out what the major IS/ICT management challenges are. The first survey was answered by 62 Swedish Chief Information Officers, CIOs, from large private enterprises as well as municipalities. The second survey was answered by twelve CIO’s from the European electric power industry. In the fifth paper, one of the IS/ICT management responsibilities, i.e. data quality, is used to illustrate how the IS/ICT manager’s responsibilities can be decomposed into measurable units. Over 70 respondents were used in order to perform an enterprise- wide measurement of the data quality at a Swedish insurance company. The last three papers are devoted to architectural principles. Architectural principles are introduced and guidelines on how to define and manage them are proposed in the sixth paper. The guidelines have been used in a review of Vattenfall’s architectural principles. In the last two papers, architectural principles and the reference model are combined in a methodology for assessing the enterprise architecture. The methodology has been used in two different case studies, one at Vattenfall and one at Scania. In both case studies multiple information systems were assessed from many different viewpoints resulting in that many respondents were interviewed.QC 20100908

It is common practice in organizational research to apply policy analysis to better understand how an enterprise is approaching and addressing a particular topic of interest. The approach to policy analysis commonly used is known as the Coding Approach. The Coding Approach is a highly qualitative process that involves the manual identification of relevant policy documents, the manual review of these documents to identify the key features of the topic, and the manual identification of the significance of these features as it relates to the policy documents. This process can generates rich insights into policies and how the topic of interest is being approached and viewed by the Stakeholder of the enterprise. This process however is a manually intensive process and is subject to the bias of the expert/s reviewing and analyzing the documents. My study proposes a new approach towards policy analysis that uses the Coding Approach as its template, but applies Machine Learning Techniques, such as Natural Language Processing and Data Mining Algorithms, together with a highly structured form of Case and Cross Case Analysis to identify documents that are related to the topic of interest, to categorize these documents, to surface the key features of the topic, to calculate the significance of these features as reflected by the documents and to draw inferences about the key features and its significance as it relates to the policy documents. This new approach provides a mixed methods approach that marries the best of both quantitative and qualitative techniques towards document analysis. This approach also reduces the amount bias that can be injected from the experts analyzing the documents, and thus guarantees an almost consistent result from document analysis regardless of the experts performing the analysis. For my study I applied my mixed methods approach to analyzing the policy documents of the Military Health Enterprise MHS, to understand how well the MHS 's policies were addressing the delivery of psychological services to service members and their families. This study is important to the MHS for two reasons. With the reductions of the US Military presence in Afghanistan and Iraq there are large numbers of veterans returning who may have various forms of PTSD, who will requires varying types and levels of care. The other reason why this study is important to the MHS is due to the recent scandals (Walter Reed, 2007 & VA, 2014) it has faced specifically around to the health care services it was supposed to provide to service members. Now its crucial for the MHS to understand the disconnect between its policies and what's actually being implemented. This study will provide the MHS with a non-bias review of what are the features of significance from a policy point of view in regards to the delivery of psychological services to service members and their families.

Full textAbstract:
With the development of economy, human concern more and more about environment protection and sustainability, especially the automotive industry, all the enterprises have been aware of that they will have no future if they cannot improve the technology of emission reduction or solve it by developing alternative energy. China has attracted lots of attention due to the rapid economy development. However, automotive industry in China, in particular, Chinese private enterprises only has short history. At present, China has been the first vehicles production country, but just for manufacture. Chinese private auto enterprises are also playing an important role in this process. What will they do after being a "Manufacture King"? In this thesis, we take BYD as a case study, use PEST, Five-forces, SWOT to analyse the factors those can affect the development of Chinese private automotive industry, besides, we also give some possible suggestions for them according to the analysis.

Full textAbstract:
s the dependence of IS/IT has grown in modern organizations, IT investments have soared in the last couple of decades. Large amounts of money are spent with the hope that the investments will generate value for the business organizations using the systems. It is hence easy to understand the needs for methods to assess the business value of IT-investments. The investment decision is basically about selecting the best IT-system or the best combination of IT-systems, i.e. the system(s) that provides the most business value in dimensions that are important business-wise. However, a problem with many of the avail-able methods is that they often fail to concretely explain what technical characteristics the IT systems(s) should have to achieve the business value desired. A complicating aspect of IT-investment evaluations is also that the evaluations usually include a high degree of un-certainty. In this thesis, an IT investment evaluation method is presented that indicatively assesses the differences in contribution to business value from IT-investment alternatives. The method provides, at a relatively low cost of investigation, indications of not only the technical differences between the IT-investment alternatives in a specific investment situation, but also an assessment of the differences in types and amounts of their business value. The presented method has been applied in a large case study at an electric power company. Furthermore, it also incorporates concepts found within Enterprise architecture (EA), particularly in how the information used in the evaluation is collected. The presented thesis is a composite thesis that, besides an introduction, includes five papers (paper A-E). Paper A presents an outline of the method as well as its application in the case study. It also presents the theoretical fundaments for the criteria used for the technical evaluation and the business value assessment including the method’s applications in relation to Enterprise architecture. The following two papers primarily present necessary steps in the development of the method. First, paper B presents the process to develop a functional reference model (used for the functional assessments in the method), including its application in the case study. Second, a breakdown of the term business value into a set of IS/IT-affected value dimension is presented in paper C. The last two papers present the final steps, i.e. the technical evaluation of the investment alternatives (paper D) and the final business value assessment (paper E). The papers include the methods to perform these analyses as well as the application of the method in the case study and the results of the case study.QC 20100608

Resumo: O atual processo de licenciamento e implantação de empreendimentos energéticos no Brasil, de acordo com a legislação vigente, exige entre outras coisas que haja uma participação da população em audiências públicas, nas quais tomam ciência dos detalhes dos projetos, seus benefícios e malefícios. Da mesma forma, os impactos negativos destes empreendimentos e os conflitos deles oriundos farão com que haja a necessidade de negociações e gerenciamento destes conflitos, onde mais uma vez a opinião pública e seus órgãos de comunicação, as mídias, deverão se manifestar. Assim, a forma de atuação das mídias poderá contribuir para um encaminhamento favorável, onde o bem geral será buscado, como também poderá influenciar em decisões equivocadas. Por tudo isso, este trabalho visa analisar a efetiva participação dos agentes envolvidos na implantação de um empreendimento energético, bem como atuação da mídia na disseminação das informações, tendo como objeto de análise a tentativa da construção dos empreendimentos de Paulínia, anterior à Rio-92, e o de Americana ¿ Carioba II, que aconteceu dez anos após, em meio às discussões para a ratificação do Protocolo de Kyoto
Abstract: The recent process of licensing and implementation energy enterprises in Brazil, according to the legislation in vigor, demands that there be the participation of the population in public audiences with the entrepreneurs. In the public audiences, the population receives information about the project details, its advantages and disadvantages. Likewise, the negative impacts of those enterprises and the conflicts originated from them will require negotiations and management of these conflicts and, once more, the public and its communication institutions, the media, must express opinion. Therefore, the manner of acting of the media may contribute to a favorable conduction of the process, leading to the population welfare, as well as influencing in mistaken decisions. For all that, this work aims to analyze the real participation of the agents involved in the implementation of energy enterprises, as well as the action of the media in disclosing information. The object of analysis of this dissertation was the attempt of implementing the energy enterprise in Paulínia, which dates before Rio-92, and in Americana ¿ Carioba II, which occurred 10 years after the first, in the midst of the discussions of the Kyoto Protocol

Full textAbstract:
While IoT safety and security incidents continue to increase in frequency, scope and severity, there remains a gap in how the issue will be addressed. While the debate continues within academia, industry standards bodies, government and industry media, new entrants continue to rapidly enter the market with cheaper more powerful products with little incentive to address information security issues. In a free market economy, the supply and the demand would determine the product and services and the associated prices without intervention. Manufacturers are free to innovate, consumers drive choice and competition brings these opposing forces to an equilibrium of market price. But how does this economic system factor in the risk of an event that neither party may ever consider and, yet, it may impact not only impact those involved, but has the potential to have catastrophic harm to others? The downside, the system does not consider “external factors”, i.e. a compromise to accommodate what consumers need. Economists often urge governments to adopt policies that "internalize" an externality, so that costs and benefits will affect mainly parties who choose to incur them. Such an intervention, however, often comes with many challenges and consequences. Even with the added urgency of growing risk to human safety, regulatory intervention takes time. Likewise, a self-regulating market would undoubtedly also take a significant amount of time to take the necessary actions to address such an externality, even if incentivized. While it continues to be all too easy to defer the blame and risk on consumer, like the industrial revolution, this industry must overcome its own safety challenges like the auto, transportation or energy industries before it. While, consumers must inevitably take some reasonable measures to protect their interests, clearly the accountability must reside elsewhere. There is a potentially increasingly significant influential subset of consumers in the IoT ecosystem, the Enterprise Buyer, specifically marketing and technology executives, who champion consumer needs within their organization’s broader products and services that incorporate IoT. In this thesis, we aim to investigate the following issue: What are the attitudes and potential role for Enterprise Buyers in influencing negative externalities, i.e. IoT security in the IoT market, specifically from the perspective of marketing and technology executives? We believe that this group is uniquely positioned to understand a consumer first mindset and how to articulate value in otherwise negatively perceived field of information security by examining context, business/technical challenges and opportunities and reveal awareness, attitude and accountability. The results of our survey show the majority of marketing and technology executives who responded believe information security awareness is increasingly an executive accountability and priority and Enterprise Buyers hold a highly influential position in their ability to influence the IoT market and its security development and maturation.Medan IoT- säkerhetsincidenter fortsätter att öka i frekvens, omfattning och svårighetsgrad, finns det fortfarande ett gap i hur problemet ska hanteras. Samtidigt som debatten fortsätter inom akademin, branschstandardorganen, myndigheter i regeringen och industrin fortsätter nya aktörer att snabbt komma in på marknaden med billigare, kraftfullare produkter med få incitament att ta itu med informationssäkerhetsfrågor. I en öppen marknadsekonomi skulle utbud och efterfrågan avgöra produkt och tjänster och tillhörande priser utan intervention. Tillverkare kan obehindrat driva innovation, konsumenterna driver urval och konkurrens ger dessa motstridiga krafter jämvikt genom marknadspriset. Men hur påverkar detta ekonomiska system risken för en händelse som ingen av parterna någonsin kan överväga och som ändå kan påverka inte bara de inblandade som berörs utan även har potential att få katastrofala skador på andra? Nersidan är att systemet inte beaktar "yttre faktorer", det vill säga gör en kompromiss för att leverera vad konsumenterna behöver. Ekonomer uppmanar ofta regeringar att anta policies som "internaliserar" något externt, så att kostnader och fördelar kommer att påverka främst parter som väljer att ådra sig dem. Ett sådant ingrepp kommer emellertid ofta med många utmaningar och konsekvenser. Trots att förhöjda hot mot människors säkerhet ökar angelägenheten tar uppdatering av regelverken tid. På samma sätt skulle en självreglerande marknad utan tvivel också ta väldigt mycket tid på sig för att vidta nödvändiga åtgärder för att hantera en sådan extern faktor, även om det fanns incitament för att göra det. Medan det fortsätter att vara alltför lätt att överlåta ansvaret och risken till konsumenten, såsom under den industriella revolutionen, måste denna industri övervinna sina egna säkerhetsutmaningar såsom bil-, transport- eller energibranschen gjort före den. Samtidigt som konsumenter oundvikligen behöver vidta rimliga åtgärder för att skydda sina intressen, måste yttersta ansvaret ligga någon annanstans. Det finns en potentiellt allt större inflytelserik delmängd av konsumenter i IoT-ekosystemet; företagsköpare, specifikt ledare inom marknadsföring och teknologi, som driver konsumentbehov inom sin organisations bredare produkter och tjänster som innehåller IoT. I denna avhandling strävar vi efter att undersöka följande problem: Vad är företagsköparnas attityder och möjliga roll för att påverka negativa externa effekter, det vill säga IoT-säkerhet på IoT-marknaden, särskilt ur marknadsförings- och teknikledarens perspektiv? Vi tror att denna grupp är unik positionerad för att förstå en konsumenternas första tankegång och hur man kan uttrycka värdet i ett annars negativt uppfattat område för informationssäkerhet genom att undersöka kontext, affärs- / tekniska utmaningar och möjligheter och avslöja medvetenhet, attityd och ansvar. Resultaten av vår undersökning visar de flesta marknadsförings- och teknikchefer som svarade tror att informationssäkerhet blir del av ledningens ansvar och prioriteringar och att företagsköpare har en mycket inflytelserik position i deras förmåga att påverka IoT- marknaden och dess säkerhetsutveckling och mognad.

Full textAbstract:
Enterprise Resource Planning (ERP) systems are used to integrate all functions of an enterprise. They often evolve from a smaller monolithic object-oriented application, covering one functional area and organically grow over time in features and size until all functional areas are covered. Once they reach certain size, unrestricted dependencies among numerous classes increase complexity of the system and make it harder for development team to create new features and maintain code stability. This creates problems to further evolution of the ERP system and poses a risk to economic consequences for company developing it. ERP refactoring strategy, together with process of its creation, is presented in this thesis. It can be used with ERP systems, having architectural issues, with a purpose to improve quality of system’s architecture and thus prolong its lifecycle. The goal of modularizing monolithic system it pursued with intention to reduce complexity and make it easier to reason about the system. This architecture-level refactoring strategy is created for one specific medium-sized ERP system through iterative trial-and-error explorative approach. This thesis is carried out at the main development site for this ERP system by project team consisting of employees working on its development. The result shows the RefStratERP, an innovative refactoring strategy consisting of target architecture, refactoring process to reach it, refactoring principles and refactoring limitations. Contrary to initial expectation, arranging domain modules (modules containing business logic) in directed acyclic graph (DAG) is, in general, not feasible without sacrificing internal module cohesion of business logic. Accidental unidirectional dependency between two domain modules is at risk of becoming bidirectional under changing business requirements. On the other hand, non-domain modules (modules without business logic) could be completely separated from domain modules in a way that domain modules depend on non-domain modules. This comes from underlying nature of business domain and the fact that functional areas of an enterprise are interdependent.Enterprise Resource Planning-system (ERP) används för att integrera alla funktioner inom ett företag. Oftast utvecklas dem från en mindre monolitisk objektorienterad applikation som täcker ett funktionellt område och växer organiskt över tiden i funktioner och storlek tills alla funktionella områden är täckta. När dem når en viss storlek ökar komplexiteten i systemet vilket gör det svårare fär utvecklingsteamet att skapa nya funktioner och hålla kodstabilitet. Detta skapar problem för fortsatt utveckling av ERP-systemet och utgör en risk för ekonomiska konsekvenser för utvecklingsföretaget. ERP refactoringstrategin, tillsammans med processen med att skapa den, presenteras i denna avhandling. Den kan användas med ERP-system, med arkitektoniska problem, med syfte att förbättra kvaliteten hos systemets arkitektur och därigenom förlänga dess livscykel. Målet att modularisera monolitiska system strävas efter i syfte att minska komplexiteten och göra det lättare att resonera kring systemet. En refaktorstrategi på arkitektnivå skapas för ett specifikt medelstort ERP-system genom en iterativ och försök-och-mistag-explorativ metod. Projektet genomfördes på ERPs huvudutvecklingsplats av ett projektteam bestående av anställda inom ERP utveckling. Resultatet visar RefStratERP, en innovativ refaktorstrategi som består av målarkitektur, refactoringprocess för att nå det, refactoringprinciper och refactoringbegränsningar. I motsats till inledande förväntningar är det i allmänhet inte möjligt att ordna domänmoduler (moduler som innehåller affärslogik) i en riktad acyklisk graf (DAG) utan att påverka interna modulsammanhang (cohesion) i affärslogiken. Oavsiktlig enriktad beroende mellan två domänmoduler riskerar att bli dubbelriktad under förändrade affärsbehov. Å andra sidan kan icke-domänmoduler (moduler utan affärslogik) helt separeras från domänmoduler så att domänmoduler beror på icke-domänmoduler. Detta kommer från underliggande egenskaper av affärsområden och det faktum att verksamhetsområden inom ett företag är beroende av varandra.

Full textAbstract:
Companies are under constant pressure to adapt and improve their processes to staycompetitive. Since most of their processes are handled by software, it also needs toconstantly change. Those improvements and changes add up over time and increase thecomplexity of the system, which in turn prevents the company from further adaption.In order to change and improve existing business processes and their implementation withinsoftware, several stakeholders have to go through a long process. Current IT methodologies arenot suitable for such a dynamic environment. The analysis of this change process shows thatfour software characteristics are important to speed it up. They are: transparency, adaptability,testability and reparability. Transparency refers to the users capability to understand what thesystem is doing, where and why. Adaptability is a mainly technical characteristic that indicatesthe capability of the system to evolve or change. Testability allows automated testing andvalidation for correctness without requiring manual checks. The last characteristic is reparability,which describes the possibility to bring the system back into a consistent and correct state, evenif erroneous software was deployed.An architecture and software development patterns are evaluated to build an overall programmingmodel that provides the software characteristics. The overall architecture is basedon microservices, which facilitates decoupling and maintainability for the software as well asorganizations. Command Query Responsibility Segregation decouples read from write operationsand makes data changes explicit. With Event Sourcing, the system stores not only the currentstate, but all historic events. It provides a built-in audit trail and is able to reproduce differentscenarios for troubleshooting and testing.A demo process is defined and implemented within multiple prototypes. The design of theprototype is based on the programming model. It is built in Javascript and implements Microservices,CQRS and Event Sourcing. The prototypes show and validate how the programmingmodel provides the software characteristics. Software built with the programming model allowscompanies to iterate faster at scale. Since the programming model is suited for complex processes,the main limitation is that the validation is based on a demo process that is simpler and thebenefits are hard to quantify.ör att fortsatt vara konkurrenskraftiga är företag under konstant press att anpassa ochförbättra sina processer. Eftersom de flesta processer hanteras av programvara, behöveräven de ständigt förändras. Övertiden leder dessa förbättringar och förändringar till ökadsystemkomplexitet, vilket i sin tur hindrar företaget från ytterligare anpassningar. För attförändra och förbättra befintliga affärsprocesser och dess programvara, måste idag typiskt fleraaktörer vara en del av en lång och tidskrävande process. Nuvarande metoder är inte lämpade fören sådan dynamisk miljö. Detta arbete har fokuserat på fyra programvaruegenskaper som ärviktiga för att underlätta förändringsprocesser. Dessa fyra egenskaper är: öppenhet, anpassningsförmåga,testbarhet och reparerbarhet. Öppenhet, hänvisar till förmågan att förstå varför, var ochvad systemet gör. Anpassningsbarhet är huvudsakligen en teknisk egenskap som fokuserar påsystemets förmåga att utvecklas och förändras. Testbarhet strävar efter automatisk testning ochvalidering av korrekthet som kräver ingen eller lite manuell kontroll. Den sista egenskapen ärreparerbarhet, som beskriver möjligheten att återhämta systemet till ett konsekvent och korrekttillstånd, även om felaktig programvara har använts. En programmeringsmodell som rustarprogramvara med de ovan beskrivna programegenskaperna är utvecklad i detta examensarbete.Programmeringsmodellens arkitektur är baserad på diverse micro-tjänster, vilka ger brafrånkopplings- och underhållsförmåga för en programvara, samt användarorganisationerna.Command Query Responsibility Segregation (CQRS) frånkopplar läsoperationer från skrivoperationeroch gör ändringar i data explicita. Med Event Sourcing lagrar systemet inte endastdet nuvarande tillståndet, utan alla historiska händelser. Modellen förser användarna medett inbyggt revisionsspår och kan reproducera olika scenarion för felsökning och testning. Endemoprocess är definierad och implementerad i tre olika prototyper. Designen av prototypernaär baserad på den föreslagna programmeringsmodellen. Vilken är byggd i Javascript och implementerarmicro-tjänster, CQRS och Event Sourcing. Prototyperna visar och validerar hurprogrammeringsmodellen ger programvaran rätt egenskaper. Programvara byggd med dennaprogrammeringsmodell tillåter företag att iterera snabbare. De huvudsakliga begränsningarna iarbetet är att valideringen är baserad på en enklare demoprocess och att dess fördelar är svåraatt kvantifiera.

Проблема забезпечення надійності енергетичних
об’єктів являється однією із найважливіших проблем енергетики на даний час.
В енергетичних системах протягом року число аварій сягає значного значення,
а обсяг електричної енергії, яку недоотримав електроспоживач в їх результаті
може сягати декілька мільйонів одиниць. В енергетичних системах оцінка
надійності устаткування та установок, знаходження шляхів підвищення
надійності стають першочерговими задачами. [19]
З залученням нової енергетичної техніки проблема надійності стає однією
з самих важливих. Відомо, що при введенні нових енергетичних об'єктів,
виявляються та усуваються причини ненадійної роботи устаткування та
установок.
Можна виділити два основних шляхи, згідно яких можна забезпечити
надійність систем електропостачання [1]: створення електроенергетичних
систем із високим рівнем надійності з використанням різних видів
резервування та забезпечення надійності елементів вдосконаленням
конструкцій та матеріалів окремих елементів. А саме краще – поєднати ці два
напрямки.

Потужність, перспективи розвитку, призначення
електроустановки та інші чинники впливають на визначення ступені надійності
електропостачання. Здатність системи електропостачання та її елементів
виконувати поставлені завдання щодо забезпечення електричною енергією
підприємств, побутових споживачів, які не призводять до зриву плану
виробництва, знеструмлення цілих житлових кварталів міст та сіл, а також не
призводять до аварій у технологічних та електричних частинах промислових
підприємств – це все характеризує надійність електропостачання. Також вона
може бути охарактеризована збитками, завданими під час перерви
електроживлення, тривалістю ремонту, часом безвідмовної роботи та іншими
факторами. [13]
Електроустановки споживачів електричної енергії мають свої специфічні
особливості. До даних установок пред'являються певні вимоги: якість
електроенергії, надійність живлення, захист і резервування окремих елементів.
При проектуванні та експлуатації систем електропостачання промислових
підприємств потрібно правильно визначати електричні навантаження,
здійснювати вибір напруг живлення, вибирати потужність та число
трансформаторних підстанцій, системи компенсації реактивної потужності,
види захисту силових трансформаторів, способи регулювання напруг. Це
повинно вирішуватися із врахуванням зростання потужностей окремих
електроприймачів, вдосконалення технологічних процесів виробництва,
особливостями кожного підприємства, установки, цеху, підвищення
ефективності та якості їх роботи. Передача, розподіл і споживання електричної
енергії на промислових підприємствах повинні здійснюватися з високою
надійністю та економічністю. [1]Розглянуто причини відмов основних елементів у системах електропостачання. Для живлення окремих електроприймачів та РП вибрана радіальна схема. Розрахована повна розрахункова потужність цеху та підприємства. Прийнято напругу лінії живлення. Розраховано центр електричних навантажень та побудована картограма навантажень. Прийнято для встановлення кількість та потужність силових трансформаторів. Здійснено розташування ЦТП територією підприємства. Запропоновано схему зовнішнього електропостачання. Проведено вибір трансформаторів ГПП. Здійснено вибір січення кабелів мереж вище 1 кВ. Виконана перевірка за допустимим навантаженням з умов нагріву в нормальному режимі та з урахуванням допустимого навантаження у післяаварійному режимі. Здійснено розрахунок струмів КЗ в мережі вище 1000 В. Здійснено перевірку та вибір обладнання у мережі вище 1000 В. Запропоновано систему автоматизованого комерційного обліку електроенергії. Здійснено вибір захисних апаратів та січень ліній, що живлять РП та електроприймачів ремонтно-механічного цеху. Побудовано епюру відхилення напруги. Здійснено розрахунок струмів КЗ у мережі до 1000 В. Побудована карта селективності дії апаратів захисту.

Full textAbstract:
Personliga eldrivna fordon (EV) är ett nytt teknikområde som är på väg att uppnå stort momentum på flera av världens marknader. Eftersom branschen fortfarande ligger i sin linda finns det i nuläget inga tydliga strukturer, som gäller för alla marknader världen över, gällande relationerna mellan aktörer, vilket leder till osäkerheter när det kommer till att ta strategiska beslut. Uppdragsgivaren för denna studie är Hong Kong EV Power Ltd. (EV Power), en Hongkong-baserad leverantör av laddningsstationer för elbilar och relaterade tjänster, som har ambitionen att inträda marknaden på det kinesiska fastlandet inom den närmaste framtiden. Emellertid har EV Power ännu inte bestämt sig vilken stad de vill rikta in sig på i det första skedet. Denna avhandling ämnar formulera en modell som kan användas för att utvärdera och jämföra geografiska marknader med avseende på lämpligheten för ett marknadsinträde av en leverantör av laddningsstationer för elbilar. Dessutom kommer modellen testas på tre städer på kinas fastland (Peking, Shanghai och Shenzhen), med syfte att komma fram till vilken stad som är mest attraktiv för EV Power, samt att utvärdera modellens funktionsduglighet. Sist kommer resultaten från utvärderingen av de tre städerna att tjäna som utgångspunkten för en analys som ämnar ta fram framgångsfaktorer för ett marknadsinträde på kinas fastland. För att uppnå detta har fyra olika datainsamlingsmetoder använts: Först studerades teori, med syfte att få bakgrundskunskap likväl som att få förståelse för specifika faktorer som påverkar ett marknadsinträde som detta. För det andra observerades EV Powers nuvarande verksamhet i Hong Kong, i avsikt att förstå vad som har lett till den framgång som företaget upplevt på sin hemmamarknad. För det tredje intervjuades branschexperter för att få ett perspektiv på branschen som helhet. Sist samlades sekundär data kring de tre städerna in, för att kunna utvärdera de olika faktorerna som ingår i den framtagna modellen. Den slutgiltiga modellen består av fem faktorer som påverkar en stads attraktivitet för ett marknadsinträde av en leverantör av laddningsstationer för elbilar. De identifierade faktorerna är: ’Marknadens tillgänglighet’, ’Kortsiktig efterfrågan’, ’Förväntad marknadsandel’, ’Vinstmarginal’ och ’Långsiktig produktpotential’. Dessa faktorer är i sin tur indelade i subfaktorer som har sina egna uppsättningar av drivare. Efter att ha använt modellen för att utvärdera de tre städerna konstaterades det att Shanghai är den lämpligaste staden för ett marknadsinträde av EV Power, främst på grund av stadens dominans på marknaden för privatanvända elbilar och ett gynnsamt regelverk. Slutligen hittades tre framgångsfaktorer för ett sådant inträde: ’Fokusera på tjänster’, ’Bibehåll partner-relationer’ och ’Inträd tidigt’.Personal electric vehicles (EV) is an emerging technology that has gained much momentum in several markets during the past decade, and China is currently one of the markets where the growth in EV sales is the highest. Since the industry is still in its infancy, there are currently no clear structures regarding the relationships between different actors that apply to all markets globally, leading to great uncertainty in strategic decisions. The commissioner of this study is Hong Kong EV Power Ltd. (EV Power), a producer of EV supply equipment (EVSE) and related services in Hong Kong, which aspires to enter the Chinese mainland in the near future. However, EV Power has yet to decide which city they want to target first. This thesis aims to formulate a model that can be used to evaluate and compare geographic markets for a market entry by an EVSE company. Furthermore, the model is tested on three cities in Mainland China (Beijing, Shanghai and Shenzhen), in order to derive the most attractive city for EV Power and to evaluate the adequacy of the model. Lastly, with the results from the city evaluation, as a point of departure, success factors for an entry into Mainland China by the commissioning company will be summarized. In order to achieve this objective, four distinct data collection methods have been used: First, theory was studied, in order to gain background knowledge as well as to understand specific factors that impact a market entry decision such as this. Second, EV Power’s current business in Hong Kong was observed, with a view to achieve an understanding of what has led the company to experience success in its home market. Third, Interviews with industry experts were conducted, so as to get a perspective on the industry as a whole. Fourth and last, secondary data for the different cities was collected, for the sake of evaluating them according to the developed model. The final model consists of five main factors that encompass the elements that influence a cities level of attractiveness for entry by an EV charging station supplier. The identified factors are: ‘Market accessibility’, ‘Short-term demand’, ‘Expected market share’, ‘Profit margin’, and ‘Long-term product potential’. These factors are in turn divided into sub factors that have their own set of drivers. Using the model to evaluate the cities, it was found that Shanghai is the most suitable city for a market entry by EV Power, mainly due to its dominance in the market for private EVs and a favourable regulatory environment. Finally, three main success factors, for such a market entry, were found: ‘Focus on services’, ‘Maintain partner relationships’, and ‘Enter early’.

Full textAbstract:
Syftet med den här studien har varit att presentera ett underlag till konstruktion av en bogvisirmodell som skall kunna gå att styras med en PLC-enhet och som kan användas i undervisningssyfte för PLC-programmering. Underlaget förankrades i verkligheten genom en fältstudie och en litteraturstudie. Fältstudien inspirerade utformandet av bogvisirmodellen och bidrog med värdefull insikt i hur bogvisir fungerar. Litteraturstudien har bestått av två delar där en del har fokuserat på att undersöka regelverk som berör konstruktion av bogvisir och den andra delen har studerat hur två katastrofer, som involverade bogöppningar, har påverkat reglerna som rör bogvisir i SOLAS-konventionen. Litteraturstudien resulterade i två sammanställningar. En sammanställning av de regler ifrån SOLAS-konventionen, Transportstyrelsen och DNV-GL som reglerar konstruktion av bogvisir och en sammanställning av hur två katastrofer som involverar bogöppningar har påverkat reglerna i SOLAS-konventionen. Materialet ifrån fältstudien och litteraturstudien har använts till att utveckla ett underlag för hur en bogvisirmodell som styrs av en PLC-enhet, och som skall gå att använda i undervisningssyfte, kan konstrueras.The purpose of this paper is to present design material that can be used to build a bow visor model which is controlled by a PLC unit and can be utilized as a tool when educating students in PLC programming. A field study and a literature study have been conducted to make the bow visor model realistic. The field study has inspired the design of the bow visor model and contributed valuable insight into the workings of a bow visor. The literature study consists of two parts where one part focused on studying regulations that regulates the design of a bow visor and the other part focused on studying how two disasters that involve bow doors have impacted the regulation in the SOLAS Convention. The literature study resulted in two compilations. One compilation consists of regulations from the SOLAS Convention, the Swedish Transportation Agency and DNV-GL regulating the design of bow visors and the other compilation consists of changes in the SOLAS Conventions regulations that are a direct result of two disasters that involve bow doors. The result of the field study and the literature study have been used to develop the design material for how a bow visor model, that is controlled by a PLC unit and can be used for educational purposes, can be built.

In the seventies of the twentieth century, there was an expansion in the production of electricity in Brazil. On April 26, 1973 the Itaipu Treaty was concluded between Brazil and Paraguay which enabled the construction of a hydroelectric plant in the border between the two countries: the Itaipu Binacional, which is governed by the Itaipu Treaty and its Annexes. The accounting of this entity presents singularities as Annex C of the Itaipu Treaty which sets the financial databases and the provision of services of Itaipu electricity and also how will the cost of electricity service will be comprised, although the depreciation of fixed assets has not been included, as a result the effect of the depreciation of the company facilities has not been presented in its financial statements, generating a communication issue, or better, the loss of accounting information quality between Itaipu Binacional and its stakeholders and this problem still affects the financial statements of ELETROBRAS (Centrais El??tricas Brasileiras S/A.) on grounds of Itaipu Binacional being constituted by ELETROBRAS and ANDE (Administraci??n Nacional de Eletricidad) with equal participation in the capital of Itaipu Binacional. This dissertation aims to analyze Itaipu Binacional accounting practices in the evaluation of its fixed assets, under the view of the Accounting Theory, and new Corporate Accounting standards as IFRS (International Financial Reporting Standards) and the new Public Accounting under IPSAS (International Public Sector Accounting Standards). To achieve these objectives a descriptive search has been conducted and a deductive method has been used as research and documentary analysis technique has been used as analysis of data. It has been observed a gap in accounting literature regarding binational ventures as Itaipu Binacional. The justifications of this study are its probable practical applicability in the Itaipu Treaty review and the possibility of Brazil joins other binational investments, governed by treaties in the area of electric power generation. In the financial statements for the financial year 2009 of Itaipu Binacional, fixed assets represented 88.22% of total assets, Itaipu accounting practices used in the valuation of fixed assets in relation to measurement, depreciation, maintenance and impairment, diverge from Accounting Theory, Corporate Accounting and Public Accounting, for nonuse of depreciation, the use of maintenance was mentioned, although its values were not presented and the impairment test was not applied in searched exercises which is briefly quoted in 2008. Another problem detected in this survey is the absence of forecast supervision by the Tribunal de Contas da Uni??o, contesting the Constitui????o Federal of the Rep??blica Federativa do Brasil and harming the accountability of Itaipu Binacional. It has been concluded that modifications are required in annex C of the Itaipu Treaty such as those that are occurring in Corporate Accounting and Public Accounting that converge to international standards.
Nos anos setenta do s??culo vinte, houve uma expans??o na produ????o de energia el??trica no Brasil. Em 26 de abril de 1973, foi celebrado o Tratado de Itaipu entre Brasil e Paraguai, o que possibilitou a constru????o de uma usina hidrel??trica na fronteira entre os dois pa??ses: a Itaipu Binacional, que ?? regida pelo Tratado de Itaipu e seus anexos. A contabilidade desta entidade apresenta singularidades como o Anexo C do Tratado de Itaipu que define as bases financeiras e de presta????o dos servi??os de eletricidade da Itaipu e tamb??m como ser?? composto o custo do servi??o de eletricidade, por??m neste custo n??o foi inclu??do a deprecia????o do Ativo Imobilizado, como consequ??ncia a empresa n??o apresenta em suas demonstra????es cont??beis o efeito da deprecia????o de suas instala????es, gerando um problema de comunica????o, ou melhor, a perda da qualidade da informa????o cont??bil entre a Itaipu Binacional e seus stakeholders e ainda este problema afeta as demonstra????es cont??beis da ELETROBRAS (Centrais El??tricas Brasileiras S/A.) em raz??o da Itaipu Binacional ser constitu??da pela ELETROBRAS e pela ANDE (Administraci??n Nacional de Eletricidad) com igual participa????o no capital da Itaipu Binacional. Esta disserta????o tem como objetivos analisar as pr??ticas cont??beis da Itaipu Binacional na avalia????o do seu Ativo Imobilizado, sob a ??tica da Teoria da Contabilidade e das novas normas da Contabilidade Societ??ria, conforme as IFRS (International Financial Reporting Standards) e da nova Contabilidade P??blica segundo as IPSAS (International Public Sector Accounting Standards). Para alcan??ar estes objetivos foi realizada uma pesquisa descritiva e utilizado como m??todo de pesquisa o dedutivo e para an??lise dos dados foi utilizada a t??cnica da an??lise documental. Foi observada uma lacuna na literatura cont??bil a respeito de empreendimentos binacionais como a Itaipu Binacional. As justificativas deste estudo s??o sua prov??vel aplicabilidade pr??tica em uma revis??o do Tratado de Itaipu e a possibilidade do Brasil participar de outros investimentos binacionais, regidos por tratados, na ??rea de gera????o de energia el??trica. Nas demonstra????es cont??beis do exerc??cio de 2009 da Itaipu Binacional o Ativo Imobilizado representa 88,22% do Ativo Total, as pr??ticas cont??beis de Itaipu utilizadas na avalia????o do Ativo Imobilizado em rela????o ?? mensura????o, deprecia????o, manuten????o e impairment divergem da Teoria da Contabilidade, Contabilidade Societ??ria e Contabilidade P??blica, quanto a n??o utiliza????o da deprecia????o, ?? mencionada a utiliza????o da manuten????o, por??m n??o s??o apresentados seus valores e nos exerc??cios pesquisados n??o foi aplicado o teste de impairment que ?? citado de maneira sucinta somente no exerc??cio de 2008. Outro problema detectado nesta pesquisa ?? a aus??ncia no Tratado de Itaipu da previs??o de fiscaliza????o pelo Tribunal de Contas da Uni??o, contrariando a Constitui????o Federal da Rep??blica Federativa do Brasil e prejudicando a accountability da Itaipu Binacional. Conclui-se assim que s??o necess??rias modifica????es no Anexo C do Tratado de Itaipu, como as que est??o ocorrendo na Contabilidade Societ??ria e Contabilidade P??blica que convergem para normas internacionais.

Previous issue date: 2005-09-06This exploratory study discusses on which are the criteria adopted, for the selection of suppliers in the Brazilian electrical sector, by companies with head offices in 16 Latin-American countries; and the existing relationship between those criteria and the answers obtained from Brazilian suppliers. First of all, we made a literary review relative to the research problem, and interviews with experts in the GTD (Generation, Transmission and Distribution of Electrical Energy) sector, where 32 variables were identified and used for the elaboration of the Survey Instrument in the Likert scale. Later, this instrument was applied to 191 respondents, being 86 of foreign companies and 105 Brazilian companies. Through the factorial analysis, the most important factors for the selection of the suppliers were identified, which are : Service and Relationship Capacity (Factor 1) ;Technical and Technological Aspects (Factor 2) ;Business Facilitators ( Factor 3); Quality and Warranty of the Products( Factor 4); Commitment and Reliability of the Products (Factor 5);Reputation of the Suppliers( Factor 6);Financial Aspects ( Factor 7). The above mentioned factors were identified as a function of four variables: 1. Origin of the Company's Corporate Capital; 2. Geographic Localization; 3. Annual Invoicing; and 4. Position of the Respondents of the surveyed companies. Through the discrimination analysis, it was noticed that the Service and Relationship Capacity factor was the one that showed the best concordance among the respondents, showing the importance in obtaining constant improvements in these items, between suppliers and purchasers. It was also noticed that the Price criterion, independently of the four mentioned variables, is considered important for all the respondents. This study offers to the purchase departments, the opportunities for the elaboration of new selection and evaluation instruments of suppliers.
O presente estudo explorat??rio discorre sobre quais s??o os crit??rios adotados na sele????o de fornecedores do setor el??trico brasileiro por empresas sediadas em 16 pa??ses latino-americanos e a rela????o existente com as respostas obtidas junto aos fornecedores brasileiros. Primeiramente realizou-se uma revis??o liter??ria sobre o problema de pesquisa e entrevistas com especialistas do setor de GTD (Gera????o, Transmiss??o e Distribui????o de Energia El??trica), onde foram identificadas 32 vari??veis utilizadas para a elabora????o do Instrumento de Pesquisa em escala de Likert. Posteriormente, este instrumento foi aplicado a 191 respondentes, sendo 86 de empresas do Exterior e 105 do Brasil. Atrav??s da an??lise fatorial, foram identificados os fatores de maior import??ncia para a sele????o de fornecedores: Capacidade de Atendimento e Relacionamento (Fator 1); Aspectos T??cnicos e Tecnol??gicos (Fator 2); Elementos Facilitadores do Neg??cio (Fator 3); Garantia e Qualidade dos Produtos (Fator 4); Comprometimento e Confiabilidade dos Produtos (Fator 5); Reputa????o dos Fornecedores (Fator 6); e Aspectos Financeiros (Fator 7), em fun????o de quatro vari??veis: 1. Origem do Capital da Empresa, 2. Localiza????o Geogr??fica, 3. Faturamento Anual e 4. Fun????o dos Respondentes das empresas pesquisadas. Foi identificado atrav??s da an??lise de discrimina????o, que o Fator Capacidade de Atendimento e Relacionamento, foi o que apresentou maior concord??ncia pelos respondentes, mostrando a import??ncia em se obter melhorias constantes nestes itens, entre fornecedores e compradores. Tamb??m foi identificado que o crit??rio Pre??o, independente das quatro vari??veis apontadas, ?? importante para todos os respondentes. Este estudo possibilita aos departamentos de compras, oportunidades para a elabora????o de novos instrumentos de sele????o e avalia????o de fornecedores.

Previous issue date: 2010-05-24This study has aimed to evaluate the reasons that have lead to the disclosure of information by Brazilian electric power companies. For this purpose, we have used the studies of Verrecchia (2001), Dye (2001), Healy and Papely (2001), and Core (2001) to form the basis of the theoretical framework. Thus, we developed seven hypotheses related to the level of disclosure and business characteristics of such companies and four control variables, as follows: (i) hypotheses: profitability, debt, size, stock control, securities issued, size of the audit company and opportunity growth and (ii) control variables: the identity of the controlling shareholder, corporate governance, ADR, and shares on BOVESPA. This research can be classified as descriptive-explanatory, since it is a description of the evolution of the level of disclosure of companies and seeks to find explanations for the motives of these levels of disclosure. The sample used was 25 publicly traded companies in the electricity sector in the period from 2003 to 2007. Regression was used with panel data for the empirical test. The result was that level of disclosure of companies surveyed suffer little evolution over the years studied in connection with the reasons that explain the level of disclosure, only variables related to size and shares listed on BOVESPA proved positive relationship.

Full textAbstract:
European Union has set a target to install nearly 200 million smart metersspread over Europe before 2020, this leads into a vast increase of sensitiveinformation flow for Distribution System Operators (DSO’s), simultaneously thisleads to raised cyber security threats. The in and outgoing information of the DSOneeds to be processed and stored by different Information technology (IT)- andOperational Technology (OT)-systems depending on the information. High demandsare therefore required of the enterprise cyber security to be able to protect theenterprise IT- and OT-systems. Sensitive customer information and a variety ofservices and functionality is examples that could be fatal to a DSO if compromised.For instance, if someone with bad intentions has the possibility to tinker with yourelectricity, while you’re away on holiday. If they succeed with the attack and shuttingdown the house electricity, your food stored in your fridge and freezer would mostlikely to be rotted, additionally damage from defrost water leaking could cause severedamaging on walls and floors. In this thesis, a detailed reference model of theadvanced metering architecture (AMI) has been produced to support enterprisesinvolved in the process of implementing smart meter architecture and to adapt to newrequirements regarding cyber security. This has been conduct using foreseeti's toolsecuriCAD, foreseeti is a proactive cyber security company using architecturemanagement. SecuriCAD is a modeling tool that can conduct cyber security analysis,where the user can see how long time it would take for a professional penetrationtester to penetrate the systems in the model depending of the set up and defenseattributes of the architecture. By varying defense mechanisms of the systems, fourscenarios have been defined and used to formulate recommendations based oncalculations of the advanced meter architecture. Recommendation in brief: Use smalland distinct network zones with strict communication rules between them. Do diligentsecurity arrangements for the system administrator PC. The usage of IntrusionProtection System (IPS) in the right fashion can delay the attacker with a percentageof 46% or greater.Europeiska Unionen har satt upp ett mål att installera nära 200miljoner smarta elmätare innan år 2020, spritt utöver Europa, implementeringen ledertill en rejäl ökning av känsliga dataflöden för El-distributörer och intresset av cyberattacker ökar. Både ingående och utgående information behöver processas och lagraspå olika IT- och OT-system beroende på informationen. Höga krav gällande ITsäkerhet ställs för att skydda till exempel känslig kundinformation samt en mängdvarierande tjänster och funktioner som är implementerade i systemen. Typer avattacker är till exempel om någon lyckats få kontroll over eltillgängligheten och skullestänga av elektriciteten till hushåll vilket skulle till exempel leda till allvarligafuktskador till följd av läckage från frysen. I den här uppsatsen så har en tillräckligtdetaljerad referens modell för smart elmätar arkitektur tagits fram för att möjliggörasäkerhetsanalyser och för att underlätta för företag i en potentiell implementation avsmart elmätare arkitektur. Ett verktyg som heter securiCAD som är utvecklat avforeseeti har använts för att modellera arkitekturen. securiCAD är ett modelleringsverktyg som använder sig av avancerade beräknings algoritmer för beräkna hur långtid det skulle ta för en professionell penetrationstestare att lyckats penetrera de olikasystem med olika sorters attacker beroende på försvarsmekanismer och hurarkitekturen är uppbyggd. Genom att variera systemens försvar och processer så harfyra scenarion definierats. Med hjälp av resultaten av de fyra scenarierna så harrekommendationer tagits fram. Rekommendationer i korthet: Använd små ochdistinkta nätverkszoner med tydliga regler som till exempel vilka system som fårkommunicera med varandra och vilket håll som kommunikationen är tillåten.Noggranna säkerhetsåtgärder hos systemadministratörens dator. Användningen avIPS: er, genom att placera och använda IPS: er på rätt sätt så kan man fördröjaattacker med mer än 46% enligt jämförelser mellan de olika scenarier.

The general objective of this study was to identify the factors that influence the decision to participate with foreign direct investment (FDI) in emerging markets in the generation of electric power. To achieve the objective proposed, first, it was identified, systematized and integrated theories, treatments and theoretical approaches on the field of economics, strategy and internationalization of enterprises that influence the strategic decision to participate with foreign direct investment (FDI) in developing countries in electric power industry, as well it was identified in the literature the main factors that determine the strategic choice to participate with foreign direct investment (FDI) in emerging markets. Based on this systematization and integration, a framework was developed incorporating new elements, which in the specific case of the electric power industry in emerging countries were not previously addressed in FDI strategies. In this work it was also identified relationships between the concepts, dimensions, subdimensions, and the variables to be tested in later studies. This study also identified and described the main features of FDI in the electric power industry in emerging countries, with two important contributions: it was observed that the investment in new technologies took place in developed countries and there was the migration of mature technologies to developing countries (compatible with product life cycle theory of Vernon) and that some studies attribute low returns to foreign investors in regulated sectors, while others highlight the high profits in international investments in regulated industries, such as the energy sector. Finally, a new concept of developing country was proposed, through the inclusion of human (human assets) and technological factors (degree of industrialization and innovation capacity) in addition to the economic factors currently used (income and economic vulnerability). It is recommended that further research be undertaken, for example, with respect to the impact of the various technologies for generation of electric power on the decision to enter emerging countries by FDI, consolidation of the data bases of the various institutions responsible for gathering information on FDI, research into the varying perceptions presented by specialists and companies in relation to the FDI strategy of companies. It is also possible to replicate this study in other segments and industries.
A presente tese tem como objetivo geral identificar os fatores que influenciam a escolha de participar no mercado de países emergentes por meio de investimento externo direto (IED) na geração de energia elétrica. Para atingir o objetivo proposto, primeiramente, foram identificadas, sistematizadas e integradas teorias, tratamentos teóricos e abordagens do campo da economia, estratégia e internacionalização de empresas que influenciam a decisão estratégica de investimento externo direto na geração de energia elétrica em países emergentes, bem como foram identificados na literatura os principais fatores considerados intervenientes ou determinantes para a escolha estratégica de realizar investimentos externos diretos em países emergentes. Com base nesta sistematização e integração, foi elaborado um framework incorporando novos elementos, que em se tratar do setor específico de energia elétrica e o contexto específico de países emergentes incorpora novos elementos, não previamente contemplados de maneira explícita em se tratar de IED. Ao longo do trabalho também foram identificadas relações entre os conceitos, as dimensões, as subdimensões e as variáveis, a serem testadas posteriormente. O presente estudo também identificou e descreveu as principais características do IED no setor de elétrico e no segmento de geração em países emergentes, com duas contribuições relevantes: há o investimento em novas tecnologias nos países desenvolvidos e a migração de tecnologias maduras para os países em desenvolvimento (compatível com a teoria do ciclo de vida do produto de Vernon) e alguns estudos atribuem baixos retornos aos investidores estrangeiros em setores regulados, enquanto outros destacam os altos ganhos nos investimentos internacionais em indústrias reguladas, como o setor de energia. Por fim, foi proposta a formação de um novo conceito de países emergentes, por meio da inserção de fatores humanos (ativos humanos) e tecnológicos (ao exemplo do grau de industrialização e da capacidade de inovação), aos fatores econômicos (renda e vulnerabilidade econômica) atualmente utilizados. A título de sugestão, considera-se pertinente a continuação da investigação iniciada nesta tese, por meio da realização de pesquisas sobre os impactos das tecnologias de geração de energia elétrica na decisão de realizar IED em países emergentes, realização de cruzamento de bancos de dados das diversas instituições atuantes no cadastramento de IED, realização de pesquisa sobre as diferenças de percepções apresentadas por especialistas e empresas com relação à estratégia de IED das empresas. Também é possível reaplicar o estudo em outros segmentos e setores.

Full textAbstract:
The dissertation uses the lens of electricity provision to examine processes of state formation in Somaliland, an unrecognized, self-declared independent state in the northwest of the former Somali Republic. The dissertation focuses on Hargeisa, the capital city at the heart of Somaliland's state-building project. After the collapse of the Somali state in 1991, private companies arose from the ruins of Hargeisa and turned the lights back on, navigating a fragmented post-war landscape by mobilizing local connections and transnational ties. However, being dependent on the political settlement that engendered the peace necessary for business, emerging private power providers were tied into a state-building project. The dissertation analyses the resulting tensions at the heart of this project, by examining the struggle to define the role, extents and limits of an emerging state in an interconnected world. Based on interviews in Somaliland and a survey of news media and grey literature, the dissertation has three aims. First, it provides a view into how social order and service provision persist after the collapse of the state. Secondly, it investigates how patterns of provision emerging in the absence of the state shape subsequent processes of state formation. Finally, it discusses how patterns of provision affect the interaction of state-building and market-making. In order to fulfil these aims, the dissertation examines how people invest in the project of building a state, both materially and discursively. The chapters present a narrative history of the electricity sector, explaining the attempts of both private companies and the government to claim sovereignty over the market and shape statehood in their own interests. The struggles shaping Somaliland's economic order reveal the contemporary significance of transnational connections, interconnected systems of capital flows, and the rise of corporate business actors. At the same time, they underline the abiding power of social structure, local identities, and historical memory.

Full textAbstract:
O presente estudo teve como objetivos elaborar o mapeamento descritivo da cultura organizacional (valores, práticas e heróis) de uma empresa de energia localizada no estado do Rio de Janeiro, identificar as principais dimensões da cultura organizacional, a possibilidade de clusters culturais e, testar empiricamente até que ponto diferenças estatisticamente mensuráveis podem ser influenciadas por diferenças de valores, práticas e heróis, bem como por fatores como, a posição hierárquica de seus membros, o fato de serem funcionários terceirizados ou não, senioridade e o nível educacional. A pesquisa foi baseada no trabalho de Hofstede et al. (1990) e Hilal (2002 e 2006) sobre as dimensões da cultura organizacional e existência de clusters culturais dentro da organização. A pesquisa possuiu duas fases. A primeira fase foi composta de cinco entrevistas qualitativas exploratórias com altos executivos da companhia que serviram para ajustar o conteúdo dos questionários da segunda fase. A segunda fase consistiu em uma survey de papel e caneta aplicada em 1.628 (um mil seiscentos e vinte e oito) funcionários operacionais para coletar informações sobre valores, práticas e heróis. Os resultados da pesquisa mostram a existência de dois clusters de cultura, ou seja, nem todos os valores e práticas são compartilhados pelos funcionários da organização. As duas principais causas constatadas para esse fenômeno estão vinculadas à capilaridade das ações do plano de transformação iniciado em 2004 pela alta-gerência e, a alta taxa de utilização de mão de obra terceirizada. Adicionalmente, o presente estudo também demonstrou existir uma diferença substancial nas percepções de cultura organizacional sob a ótica gerencial (entrevistas qualitativas), na maioria das vezes relacionadas ao comportamento desejado, quando confrontada com os valores e práticas em uso (resultados da pesquisa quantitativa).This study had the objective of elaborating the descriptive mapping of theorganizational culture (values, practices and heroes) of a distributor company of electric energy located in the state of Rio de Janeiro, also identifying the main organizational culture dimensions, the possibility of cultural clusters and empirically test how statistically measurable differences can be influenced by diferences perceived in values, practices and heroes, as well as factors as the hierarchical position of its members, the fact that the employees be outsourced or not, seniority and educational level. The research was based on the work of Hofstede et al. (1990) and Hilal (2002 and 2006) on the cultural dimensions of organizational culture and on the existence of clusters inside the organization. The research had two stages. The first stage involved five qualitative exploratory interviews with high company executives, which were used to adjust the contents of the survey of the second stage. The second stage consisted of a paper and pencil survey applied to 1.628 (one thousand six hundred and twenty eight) operational employees to collect information about values, practices and heroes. The results of the research show the existence of two cultural clusters, in other words, not all the practices, values, and heroes are shared by all the employees of the company. The two main causes that explain this phenomenon are related to the capillarity of the actions of the transformation plan initiated in 2004 by the highmanagement and, the high rate of outsourced labor. Additionally, the present study also indicate the existence of a substantial difference in the way the organizational culture of the company is perceived by management (qualitative interviews), mostly related to desired behaviors, and the perspective of non-managerial employees, mostly reflected in the practical values in use (quantitative research / survey).

After China becomes the manufacturing plant of the world ,its competitive advantage on cheap production cost attracts a lot of foreign enterprises to invest. Under this huge competition pressure, the manufacturing capacity which Taiwan originally regards as a pride, especially ODM manufacturer, there is very great possibility that will be annexed by the mainland. Under this kind of competition, the BIPA（Brand International Promotion Association） is established in 1989. In addition, the government assist the Taiwan enterprises, to create international brand on a large scale，especially in electrical and computer industries. Even under the pressure, we have created another world in international marker. To watch the relationship between the brand extension and the subjective brand equity, this research adopts only the view of the subjective brand equity, including two main variables: the brand awareness and the brand image, In the questionnaire issued actually, dividing into the high outcome of the brand extension，Acer，and the low outcome of the brand extension，D-Link. Acer is 170 pieces of questionnaire issued ,and D-Link is151 pieces of questionnaire issued. The research shows ,the first, it has significance between the brand image and the brand extension, it does not have significance between brand awareness and the brand extension. The second during the process of influencing brands to extend, the interaction between the brand awareness and the brand image is not significant. The third, the outcomes of the brand extension are more, and the subjective brand equity effects more, and vice versa.

Since 1986, Vietnam government adopted innovation policy and modified the national development routes. Opening FDI was one of the main polices. The Government was actively attracting foreign companies and hoped Vietnam’s economy can be developed by investing of foreign capital and technology. National construction and mechanical/ electrical industry have set foot on the Vietnamese market for years. In this research, we study and analyze the method of Analytic Hierarchy Process (AHP), to discuss the factors that effect to the outward FDI of Taiwan enterprises and their successes. Based on many research results, we set up a structure among successful factors of Taiwan enterprises, who outward FDI in Vietnam’s construction and mechanical/ electrical industry, and got 3 main configurations, 17 major factors. Investment in the construction and mechanical/ electrical industry in Taiwan investment in Vietnam, the reasons linked to the investment management problems encountered in Vietnam, then division of the key factors in the practice, and finally Based on the results of the construction and mechanical/ electrical industry investment in Vietnam, some ideas, and provide advice to management scholars reference.

Xia, Jianhong. "Understanding Internet infrastructure and securing enterprise networks." 2007. https://scholarworks.umass.edu/dissertations/AAI3254943.
Full textAbstract:
The success of the Internet has brought out extraordinary benefits to our society. Current Internet infrastructure has become much more complicated than that in the early 90's when it was first deployed for commercial use. Due to limitations in the initial design of the Internet, security issues are not well addressed. Thus, the Internet has been confronted with many security problems such as worm attacks and Internet infrastructure vulnerabilities. To address these problems, this dissertation focuses on developing various strategies for securing enterprise networks and Internet infrastructure. The Internet consists of thousands of distinct regions of administrative domains, each of which possesses a set of Autonomous Systems (ASes). With the rapid growth of the Internet in both scale and complexity, understanding its infrastructure is critical to ensure the reliable and efficient operation of the Internet. This has led to the first part of our work. The connectivity of the Internet does not imply the reachability from one network to another. Routing policies among Internet Service Providers (ISPs) play an important role, which are determined by commercial relationships among them. Although such information is desirable for Internet related research, not all ISPs are willing to publish it. It becomes necessary to infer AS relationships from other public resources to understand the network reachability. Our first part of work evaluates existing algorithms on inferring AS relationships and proposes an improved algorithm that achieves a better accuracy on the inference results. Maintaining network reachability is far from enough for enterprise networks since malicious attacks may deplete network resources and degrade network performances. The second part of our work is to develop strategies for securing enterprise networks against worm attacks. We propose an algorithm on worm detection and quarantine using sequential hypothesis testing. Both analytical and experimental results show that our algorithm can protect enterprise networks effectively from generic worm attacks. In addition to worm attacks, there are malicious attacks exploiting the vulnerabilities in the Internet infrastructure, which may result in more severe damages by impacting the networks on a large-scale. We address two security issues along this line. One issue is the persistent forwarding loops that may be exploited to launch flooding attacks. The other is the design flaws in router architecture that may be exploited to impact the functionality of routers and routing protocols. Regarding the vulnerability of persistent forwarding loops, we perform an extensive measurement in the Internet to understand its scope, i.e., the number of network addresses that has experienced persistent forwarding loops and the number of addresses that will be impacted indirectly by the loops. We also characterize the properties of persistent forwarding loops in terms of length and location. By emphasizing their potential damage, we also investigate the possible causes of persistent forwarding loops. Regarding the design flaws in router architecture, we analyze the impact of control path congestion on the behavior of Border Gateway Protocol (BGP). Our results show that attacks exploiting this vulnerability can reset BGP sessions within 10 minutes, which may lead to global routing instability in the Internet. In addition, we discuss feasible solutions to mitigate such problems and provide suggestions in practice to secure the Internet infrastructure. The major contributions of this dissertation include the analysis on potential vulnerabilities in the Internet infrastructure and the development of worm detection and quarantine algorithms to secure enterprise networks. We assess the Internet infrastructure vulnerability by both analytical and experimental studies, and highlight that misconfigurations and design flaws in routers may cause serious security problems in the Internet.
