Abstract:

Developing complex sociotechnical systems often involves integrating new technology into existing systems by applying systems engineering processes. This requires an understanding of the problem space and the possible impact of the new technology. Systems engineering uses modelling to explore the structural, functional, and operational elements of the problem and solution space (Hitchins 2008). Historically, systems engineering has however struggled with complex sociotechnical systems projects, as it cannot cope with the dynamic behaviour of complex sociotechnical systems. The hypothesis of this thesis is that addressing the contribution of humans performing work in a complex, constrained and dynamic environment using modelling will result in a better understanding in the analysis phase; it should also lead to improved requirements, designs, selection of technologies, and implementation strategies, enabling sociotechnical systems to cope with complex operating environments. A sociotechnical system consists of humans applying technology to perform work through processes within a social structure (organisation) aimed at achieving a defined objective (Bostrom & Heinen 1977, Walker et al. 2009). Work can become complex due to non-linear and dynamic interaction among the people themselves, among people and technology, as well as among people and the environment. Complexity may lead to “wicked and messy” problems, as many unintended or unpredicted consequences may be experienced. The new technology may also lead to new task possibilities that evolve user requirements (Carroll & Rosson 1992). Systems engineering, as developed in the 1950s, forms the basis of developing systems, including sociotechnical systems. Classic systems engineering processes assume that problems can be isolated and decomposed, making the development of complex sociotechnical systems difficult. One way to improve the success of systems engineering is to ensure that the problem to be solved is properly understood. Analysis of the problem and solution space involves capturing and modelling the knowledge and mental models of the stakeholders, to support understanding the system’s requirements. A good description of the problem situation through a model is the first step towards designing and developing a solution. The aim of this study is to develop and demonstrate a modelling methodology for complex sociotechnical systems, in support of the systems engineering process. The two approaches used in the modelling methodology are cognitive work analysis and system dynamics. Cognitive work analysis is a framework for analysing the way people perform work in an organisation, while taking the environmental constraints into consideration. The outputs of cognitive work analysis are constructs or models that capture the structure of the problem. Functions provided by different technological elements are linked to the functional requirements of the system, to achieve its purpose (Lintern 2012). However, cognitive work analysis is limited in investigating the dynamic effect of decisions and policies on the system (Cummings 2006). The dynamic behaviour of complex sociotechnical systems can be analysed using system dynamics, which uses the structure of the system in simulation. System dynamics analyse the effect of feedback and delays on operating the system, as a result of decisions based on policies (Sterman 2000). The design science research framework, which also supports the research design of this thesis, is used to implement the modelling and structure the methodology. Design science research aims at creating technology for a human purpose, unlike the natural sciences, which are geared towards attempting to understand and define reality (March & Smith 1995). The proposed methodology is demonstrated in a case study using modelling and analysis of the impact of a new collaboration technology on command and control systems. Command and control is a good example of a complex sociotechnical system, as humans use technology to assemble and analyse information for situation assessment in support of planning operations (Walker et al. 2009). These systems are also used to control the successful implementation of plans in constrained and variable operating environments. The modelling methodology is demonstrated by modelling and assessing the effect of a new command and control technology for border safeguarding operations, anti-poaching operations and community policing forums. The new technology to be implemented in these complex sociotechnical systems is called “Cmore”. It is a web-based collaboration system that uses smartphones to capture information and track users. Even though the three demonstrations constitute similar systems, the different contextual situations result in diverse behaviour and issues to be investigated. The demonstrations centre on the functions of situation awareness and decision support. The different output models for the command and control systems are used in system dynamics simulations to assess the effect of new technology on the operating and effectiveness of a system. The case studies demonstrated that the modelling methodology support learning about the implementation of a new technology in various complex sociotechnical systems. The developed models and constructs also supported developing evaluation templates during the planning of experiments through identifying key issues. The system dynamics simulations used parametric inputs to investigate the behaviour of the system. In most cases, the simulation outputs identified interesting and counter-intuitive behaviour for deeper assessment. The community policing forum case study also gathered qualitative empirical evidence on the system's behaviour, during a field experiment. The outcomes are compared with the models and simulation outputs to improve the system behavioural models. The learning and improved understanding of the complex sociotechnical system behaviour gained through the modelling methodology, demonstrated its utility.

Abstract:

In public spaces, we constantly interact with each other - whether we are aware of it or not. Most of these interactions are indirect and subtle, ranging from flâneurial people-watching, over negotiation of turns in urban traffic, to passive aggression. This is not only true for pedestrians, but equally so for bicyclists.Bicycling is an embodied and social practice. When designing for cycle-based experiences, interaction designers face many problems while conducting research: mobility is always on the move and therefore hard to capture; the fleeting moments of interaction are almost imperceptible to the eye; and verbal accounts of bicyclists cannot represent the experiential qualities of a ride properly.While there exists a history of ethnographic studies into bicyclists' behaviour, it proves to be difficult to enquire into these more subtle interactions. More conventional representations of experience, such as video, fail to capture many of the qualities inherent in taking a ride and being 'out there'. It would be naive to neglect these qualities in our research when designing for cycle-based interaction.This thesis builds on the work of ethnographers and designers engaged in bicycling research. It explores new ways of enquiry that help researchers find out what really happens on the saddle and beyond.

Abstract:

Much of the software in the world today was developed from the mid-1960s to the mid- 1970s.This legacy software deteriorates as it is modified to satisfy new organizational requirements. Currently, legacy system maintenance requires more time than new system development. Eventually, legacy systems must be replaced. Identifying their functionality is a critical part of the replacement effort. Recovering functions from source code is difficult because the domain knowledge used to develop the system is not routinely retained. The source code is frequently the only reliable source of functional information. This dissertation describes functional process information recovery from COBOL source code in the military logistics system domain. The methodology was developed as an information processing application. Conceptual and logical models to convert source code to functional design information were created to define the process. A supporting data structure was also developed. The process reverse engineering methodology was manually applied to a test case to demonstrate feasibility, practicality, and usefulness. Metrics for predicting the time required were developed and analyzed based on the results of the test case. The methodology was found to be effective in recovering functional process information from source code. A prototype program information database was developed and implemented to aid in data collection and manipulation; it also supported the process of preparing program structure models. Recommendations for further research include applying the methodology. to a larger test case to validate findings and extending it to include a comparable data reverse engineering procedure.

The thesis deals with non-adherence in connection with medication and the major problems that arise if a patient does not follow the medical advice. Non-adherence is a major problem today, both for society and for the individual. For society is is very costly to handle all medication errors and for the individual it can be about life or death. The purpose of this thesis is to develop an IT artifact with the purpose of improving adherence for patients taking medication daily. This is done by using a mobile application that uses Bluetooth for positioning the medicine. The artifact will serve as a support and aid by facilitating a patient that is taking medication. This research uses Design Science Research Methodology (DSRM). Contributing company in this work have been Knowit Luleå. The work resulted in an IT artifact, as well as six design principles, all based on the problem of non-adherence in order to contribute to improved adherence.

Abstract:

Every day large volumes of data are collected in the form of time series. Time series are collections of events or observations, predominantly numeric in nature, sequentially recorded on a regular or irregular time basis. Time series are becoming increasingly important in nearly every organisation and industry, including banking, finance, telecommunication, and transportation. Banking institutions, for instance, rely on the analysis of time series for forecasting economic indices, elaborating financial market models, and registering international trade operations. More and more time series are being used in this type of investigation and becoming a valuable resource in today�s organisations. This thesis investigates and proposes solutions to some current and important issues in time series data management (TSDM), using Design Science Research Methodology. The thesis presents new models for mapping time series data to relational databases which optimise the use of disk space, can handle different time granularities, status attributes, and facilitate time series data manipulation in a commercial Relational Database Management System (RDBMS). These new models provide a good solution for current time series database applications with RDBMS and are tested with a case study and prototype with financial time series information. Also included is a temporal data model for illustrating time series data lifetime behaviour based on a new set of time dimensions (confidentiality, definitiveness, validity, and maturity times) specially targeted to manage time series data which are introduced to correctly represent the different status of time series data in a timeline. The proposed temporal data model gives a clear and accurate picture of the time series data lifecycle. Formal definitions of these time series dimensions are also presented. In addition, a time series grouping mechanism in an extensible commercial relational database system is defined, illustrated, and justified. The extension consists of a new data type and its corresponding rich set of routines that support modelling and operating time series information within a higher level of abstraction. It extends the capability of the database server to organise and manipulate time series into groups. Thus, this thesis presents a new data type that is referred to as GroupTimeSeries, and its corresponding architecture and support functions and operations. Implementation options for the GroupTimeSeries data type in relational based technologies are also presented. Finally, a framework for TSDM with enough expressiveness of the main requirements of time series application and the management of that data is defined. The framework aims at providing initial domain know-how and requirements of time series data management, avoiding the impracticability of designing a TSDM system on paper from scratch. Many aspects of time series applications including the way time series data are organised at the conceptual level are addressed. The central abstraction for the proposed domain specific framework is the notions of business sections, group of time series, and time series itself. The framework integrates comprehensive specification regarding structural and functional aspects for time series data management. A formal framework specification using conceptual graphs is also explored.

Smart city is an approach to managing and coping with urban challenges in search for innovative solutions leading to better quality of life and sustainability in cities. Several initiatives have been undertaken, with a significant worldwide growth trend in the coming years. Such initiatives, however, may require non-trivial public investment, and failures resulting from them can have important consequences such as monetary loss, loss of reputation, reduced confidence and lack of public value. This research aims at setting a methodology in smart cities composed of a reference model and an assessment method from the Public Value perspective. These artifacts were evaluated based on the perception of 23 representatives of the Quadruple Helix (government, industry, university and citizens) and on the results of the applicability in practice, through an initial pilot evaluation, in the city of Nova Santa Rita. It follows Design Science as its epistemological paradigm and Design Science Research as its method, uniting theoretical and methodological rigor as well as practical utility for society. The results showed that the artifacts developed in this research can help in the design and assessment of smart cities in a gradual way, bringing together best practices considered intelligent and that allow for the expansion and/or generation of Public Value, consisting of a prescriptive scientific contribution. Among the contributions are the protocol, contingency and construction heuristics, which detail how these artifacts were rigorously designed and developed, under the Design Science paradigm, to solve the problem identified in this research. They are specific and useful knowledge, generated from this research, aimed at the practice and resolution of real problem, and can be used for future evolutions of the artifacts developed in the research and/or design of new artifacts, in different contexts and classes of problems.

Abstract:

The world is facing a food shortage as the world’s population increases and arable land decreases. Despite this, the food industry is wasteful, and 30% - 40% of all produced food is lost before reaching the end consumer. Emerging technologies aim to increase the amount of food that can be grown per m2 or allow the growing of food in climates or on lands previously impossible. Four main farming techniques utilising these emerging technologies are Controlled Environment Agriculture, Hydroponic Farming, Urban Farming and Vertical farming. When used together, these techniques form the basis for what can be called a Plant Factory. Despite the positive effects these technologies have on the production rate, few Plant Factories have managed to achieve profitability. By creating support for developing the post-harvesting system for a plant factory, this thesis aims to aid in the development of profitable plant factories. The thesis uses Design Research Methodology to achieve this aim in three parts. The first part identifies the underlying factors of the post-harvesting system affecting plant factory profitability. The second presents a set of support components that will aid the developers to improve key factors affecting profitability. The third part is a case study where the support components applicability at targeting the key factors are evaluated, and suggestions for further improvements and testing of the support is suggested. Further, using Design Research Methodology, the methods used to develop support in this thesis are presented to easily be replicated by other researchers to aid them in developing support for other industries and circumstances. The suitability of the developed support was tested using the principles of an initial DS-II. The developed support proved very useful for the investigated case, and with its conditions, the application evaluation was considered a partial success. Two key factors were successfully improved and indicated that the intended support is ready for a comprehensive DS-II. A third support component needs more work to provide the intended support fully. Therefore a second PS iteration is recommended before a comprehensive DS-II is done to increase its value.

Abstract:

Within undergraduate mathematics education, there are few validated instruments designed for large-scale usage. The Group Concept Inventory (GCI) was created as an instrument to evaluate student conceptions related to introductory group theory topics. The inventory was created in three phases: domain analysis, question creation, and field-testing. The domain analysis phase included using an expert consensus protocol to arrive at the topics to be assessed, analyzing curriculum, and reviewing literature. From this analysis, items were created, evaluated, and field-tested. First, 383 students answered open-ended versions of the question set. The questions were converted to multiple-choice format from these responses and disseminated to an additional 476 students over two rounds. Through follow-up interviews intended for validation, and test analysis processes, the questions were refined to best target conceptions and strengthen validity measures. The GCI consists of seventeen questions, each targeting a different concept in introductory group theory. The results from this study are broken into three papers. The first paper reports on the methodology for creating the GCI with the goal of providing a model for building valid concept inventories. The second paper provides replication results and critiques of previous studies by leveraging three GCI questions (on cyclic groups, subgroups, and isomorphism) that have been adapted from prior studies. The final paper introduces the GCI for use by instructors and mathematics departments with emphasis on how it can be leveraged to investigate their students' understanding of group theory concepts. Through careful creation and extensive field-testing, the GCI has been shown to be a meaningful instrument with powerful ability to explore student understanding around group theory concepts at the large-scale.

Le monde des entreprises a connu par le phénomène du Big Data un bouleversement extraordinaire. Véritable Big Bang technologique, le Big Data a ouvert des perspectives formidables en matière de développement par le biais du traitement et de l’analyse des données qu’il génère. Dans l’absolu, le potentiel que contient le Big Data est un élément majeur en matière de compétitivité mais il apparait cependant aujourd’hui que la maîtrise de ce potentiel est fortement compromise ou freinée par une somme de problématiques liées à l’ampleur du phénomène ; les méthodologies traditionnelles s’essoufflent et se montrent de moins en moins performantes. Cette recherche propose d’apporter une contribution susceptible de faciliter le passage entre une analyse classique et une analyse novatrice en environnement Big Data. En suivant la méthodologie de la Science du Design, nous proposons de créer un artefact, sous forme de guide méthodologique, composé d’un ensemble de solutions de machine learning empruntées aux Data Science, mis à disposition des entreprises pour aider à l’accès, à la compréhension, à l’utilisation et à l’analyse des données massives
.The world of corporations was revolutionized under the impact of the Big Data phenomenon. Truly a technological Big Bang, Big Data opened many doors towards research and development because of the analysis and treatment it requires. Big Data has always been recognized with a highly competitive potential, however today it appears that there is trouble in controlling this potential. The reason is a number of problems arising linked to size of the revolution; traditional methods are starting to be obsolete and are less effective. This research aims at proposing a contribution to making the transition easier between a classical analysis and innovative analysis. Following the methodology of the Science of Design, we propose creating an artifact that takes form in a methodological guide. It will be composed of a set of machine learning solutions that take root in data science. They will be made available to companies to help the access, the comprehension, and the usage of Big Data

Abstract:

The research reported and discussed in this thesis represents a novel approach to define custom gestures and to include gesture-based interaction in user interfaces of the software systems with the aim of help to solve the problems found in the related literature about the development of gesture-based user interfaces. The research is conducted according to Design Science methodology that is based on the design and investigation of artefacts in a context. In this thesis, the new artefact is the model-driven method to include gesture-based interaction in user interfaces. This methodology considers two cycles: the main cycle is an engineering cycle where we design a model-driven method to include interaction based on gestures. The second cycle is the research cycle, we define two research cycles: the first research cycle corresponds to the validation of the proposed method with an empirical evaluation and the second cycle corresponds to the technical action research to validate the method in an industrial context. Additionally, Design Science provides us the clues on how to conduct the research, be rigorous, and put in practice scientific rules. Besides Design Science has been a key issue for organising our research, we acknowledge the application of this framework since it has helps us to report clearly our findings. The thesis presents a theoretical framework introducing concepts related with the research performed, followed by a state of the art where we know about the related work in three areas: Human-computer Interaction, Model-driven paradigm in Human-Computer Interaction and Empirical Software Engineering. The design and implementation of gestUI is presented following the Model-driven Paradigm and the Model-View-Controller design pattern. Then, we performed two evaluations of gestUI: (i) an empirical evaluation based on ISO 25062-2006 to evaluate usability considering effectiveness, efficiency and satisfaction. Satisfaction is measured with perceived ease of use, perceived usefulness and intention of use, and (ii) a technical action research to evaluate user experience and usability. We use Model Evaluation Method, User Experience Questionnaire and Microsoft Reaction cards as guides to perform the aforementioned evaluations. The contributions of our thesis, limitations of the tool support and the approach are discussed and further work are presented.

L'objectiu és ajudar a resoldre els problemes trobats en la literatura relacionada al desenvolupament d'interfícies basades en gests d'usuaris. Aquest treball d'investigació ha sigut realitzat d'acord a la metodologia Ciència del Diseny, que està basada en el disseny i investigació d'artefactes en un context. En aquesta tesi, el nou artefacte és el mètode dirigit per models per incloure interacció basada en gests en interfícies d'usuari. Aquesta metodologia es considerada en dos cicles: el cicle principal, denominat cicle d'enginyeria, on es dissenya un mètode dirigit per models per incloure interacció basada en gestos. El segon cicle és el cicle de la investigació, on es defineixen dos cicles d'aquest tipus. El primer es correspon a la validació del mètode proposat amb una avaluació empírica i el segon cicle es correspon a un Technical Action Research per validar el mètode en un context industrial.

Abstract:

Den projektbaserade arbetsformen blir allt mer vanligt förekommande inom alla nivåer i samhället. Projekt kräver planering, bland annat tid- och resursplanering. Tid är en av de viktigaste beståndsdelarna i projekt, och tidsaspekten är av avgörande betydelse om projektet kommer att lyckas i sin helhet. Resurser är en annan viktig beståndsdel som också har en avgörande betydelse om projekt kommer att nå målen. Samtidigt som projektet som arbetssätt tilltar, tenderar projekten att växa i storlek. Statistiken gör gällande att stora projekt ofta misslyckas ett problem som inte har minskat, trots mångåriga erfarenheter från projekt. Även om utbudet av metoder, tekniker och programverktyg är tämligen omfattande idag, kvarstår problemet med misslyckade projekt, trots mer erfarenhet och fler verktyg. Det råder ett generellt problem med att projekttiden minskar, i kombination av att komplexiteten ökar i alla former av projekt. Omständigheter som medfört större krav på projektplanering, särskilt tid- och resursplanering. Det kan antas att det finns ett behov av datoriserade projektplaneringsprogram, och antagandet att det är svårt att tid- och resursplanera utan stöd av olika metoder, tekniker och datorverktyg.Studiens syfte är att undersöka hur projektplanering i allmänhet och tid- och resursplanering i synnerhet bedrivs idag, och hur de olika metoderna, teknikerna och programverktygen kan förbättra, och underlätta projektplaneringen.

Abstract:

Volvo Construction Equipment is considering applying modular design to their organisation in order to constrain the growing intangible information and parts assortment within the company, and as well to enable a rearrangement of production, sales and logistics in the near future of organisational growth and industrial footprint. Hence the purpose of this thesis is to investigate the opportunities and threats of implementing modular design to Volvo Construction Equipment. The analysis is scoped on the generic aspects of modularity and the organisational weaknesses within Volvo CE towards implementing a new organisational structure, product design and production with modular design. Modularity enables the company to move towards decupling the constraints of tangible sales and provides an opportunity to offer Product Service Systems as a Total Solution for each individual customer. By implementing the authors common knowledge and education within engineering revolving tangible and intangible products and services alongside with innovation, together with informal interviews of stakeholders, the results of the thesis was reached. The analysis of the results was reached by implementing Design Research Methodology to the structure of the thesis, research method and interviews made. There is a distinct opportunity for Volvo CE to implement modular design since the informational flows, innovation, research and development is enhanced by a correct modular design. Although there is a distinct risk in changing a well-established product design, development process and organisational structure, the opportunities to create a product service system strategy and to re harvest and recycle value within the company with modularity outweigh the risk. Incomprehension of how to optimize a modular design may amplify the reasons why Volvo CE is considering revising their products and organisation with modularity, thus the authors recommend implementing a generic and specific education in modularity within Volvo CE to ensure a shared language of modularity and enhance traceability of the development within the company. In order to enhance the organisational velocity around development, the authors also recommend a new computer environment which enables the different disciplines of engineering and marketing to modularise the product, services and processes while keeping the comprehension of the subject close to hand. This enables the organisational structure to change and improve towards modular deployment and to further accelerate Volvo CE’s growth, market share and revenue.
Volvo Construction Equipment överväger att tillämpa en modulär design till sin organisation i syfte att begränsa den växande immateriella information och det växande sortiment av delar inom företaget som finns idag. Volvo ser även till möjligheterna med modulär design för att möjliggöra en omflyttning av produktion, försäljning och logistik inom den närmaste framtiden för organisatorisk tillväxt och för att minska det industriella fotavtrycket. Därav syftet med denna uppsats; att undersöka möjligheter och hot för att genomföra modulär design i Volvo Construction Equipment. Analysen är fokuserad på generiska aspekter på modularitet och organisatoriska svagheter inom Volvo CE mot att genomföra en ny organisationsstruktur, produktdesign och produktion med modulär design. Modularitet möjliggör för företaget att gå mot att minska begränsningen av materiell försäljning och ger en möjlighet att erbjuda system med Product och Service lösningar som en helhetslösning för varje enskild kund. Genom att implementera författarnas gemensamma kunskap och utbildning inom teknik roterande kring materiella och immateriella produkter samt tjänster tillsammans med innovation, och med informella intervjuer av intressenter, har resultaten i denna avhandling uppnåtts. Analysen av resultaten uppnåddes genom att implementera metodiken Design Research Methodology till strukturen, forskningsmetod och gjorda intervjuer i avhandlingen. Det finns en tydlig möjlighet för Volvo CE att genomföra modulär design eftersom de informativa flöden, innovation, forskning och utveckling förstärks av en korrekt modulär design. Även om det finns en klar risk i att ändra en väletablerad produkts design, utveckling process och organisations struktur, är möjligheterna i att skapa en produkt strategi med servicesystem och att återvinna återvinna värde i företaget med modularitet väl värt risken. Oförståelse för hur man optimerar en modulär design kan innebära ytterligare risker och förklarar varför Volvo CE överväger revidera sina produkter och organisation med en ny design, och då kanske en modulär struktur. Detta har lett till att författarna rekommenderar att genomföra en allmän och specifik utbildning i modularitet inom Volvo CE för att säkerställa ett gemensamt språk för modularitet och öka spårbarheten av utvecklingen inom företaget. För att öka den organisatoriska hastigheten kring utveckling, rekommenderar författarna också en ny datormiljö som gör att de olika disciplinerna i teknik och marknadsföring ligger närmre till hands för att modularisera produkter, tjänster och processer samtidigt som förståelsen av ämnet blir enklare att uppnå. Detta maximerar effektiviteten i den organisatoriska strukturen för att förändra och förbättra mot en modulär utbyggnad och att ytterligare påskynda Volvo CE : s tillväxt , marknadsandelar och intäkter

Statistical process variations have long been an important design issue. But until recently, process variations have been global process variations, i.e., transistor parameters may vary from die to die but are constant within a die. With transistor geometries shrinking below 65nm, however, a new kind of statistical variation, known as Local or Intra-die variation, has become important for logic and memory. Local variations are primarily the result of variations in the number of dopant atoms in the channel of CMOS transistors. To achieve ultra-low power, ICs are being designed for VDD by Rahul Rithe.

Abstract:

User Experience Engineering (UxE) incorporates subject areas like usability, HCI, interaction experience, interaction design, "human factors", ergonomics", cognitive psychology", behavioral psychology and psychometrics", systems engineering", [and] "computer science," (Hartson, 1998). It has been suggested that UxE will be the main success factor in organizations as we enter the "loyalty decade" of software development, where the repeat usage of a product by a single customer will be the metric of product success (Alghamdi, 2010; Law & van Schaik, 2010, p. 313; Nielsen, 2008; Van Schaik & Ling, 2011). What is relatively unknown in the current academic literature is whether existing UxE methodologies are effective or not when placed in a longitudinal research context (Law & van Schaik, 2010). There is room for the exploration of the effects of long-term UxE practices in a real-world case study scenario. The problem, addressed in this study, is that a lack of the application of UxE-related processes and practices with an industrial partner had resulted in customer dissatisfaction and a loss of market share. A three-year case study was performed during which 10 UxE-related metrics were gathered and analyzed to measure the improvements in the design of the customer's experience that long-term UxE practices could bring to a small corporate enterprise. The changes that occurred from the corporate and customer's point of view were analyzed as the customer's experience evolved throughout this long-term UxE study. Finally, an analysis of the problems and issues that arose in the implementation of UxE principles during the application of long-term UxE processes was performed. First-hand training between the research team and company employees proved essential to the success of this project. Although a long-term UxE process was difficult to implement within the existing development practices of the industrial partner, a dramatic increase in customer satisfaction and customer engagement with the company system was found. UxE processes led to increased sales rates and decreased development costs in the long-term. All 10 metrics gathered throughout this study showed measurable improvements after long-term UxE processes and practices were adopted by the industrial partner.

Abstract:

No âmbito das organizações empresariais, é premente a necessidade constante de lançamento de novos produtos e serviços em função da redução do time to market, o que vem requerendo maior precisão nas decisões de portfólio de oportunidades de inovação. Em específico, as questões de portfólio vêm sendo tratadas primordialmente na gestão de produtos e projetos, o que acaba por ocorrer tardiamente no Processo de Desenvolvimento de Produtos (PDP), com preocupações concentradas na revisão ou gestão do portfólio de produtos e/ou projetos. Desta forma, há um descompasso entre a geração de oportunidades de inovações e o aproveitamento destas, como produtos e projetos, o que prejudica as organizações na identificação e valoração de suas inovações; na antecipação de oportunidades que venham a se tornar inovações; no equilíbrio das escolhas dentre vários critérios inclusive não financeiros; bem como, no direcionamento do portfólio a partir de uma estratégia harmônica. Visando instrumentalizar as organizações para suprir estas dificuldades, uma vez que elas carecem de métodos e técnicas que tratem o portfólio de forma mais ampla, o objetivo da pesquisa foi propor um Método de Referência na Geração do Portfólio de Oportunidades de Inovação (MERGE-OI), o que possibilitou que organizações empresariais brasileiras gerassem e selecionassem um portfólio de oportunidades de inovações de forma mais precisa, independente de seu porte e segmentação econômica. O MERGE-OI foi aplicado em cinco empresas representativas de três segmentos econômicos: alimentos e bebidas, construção civil e eletroeletrônico. A aplicação em campo permitiu validar a sua consistência e coerência. Quanto aos métodos, esta pesquisa é primordialmente observacional e de análise de conteúdo, sendo que, os mesmos foram empregados tanto como métodos quanto técnicas, o que consolidou o desenvolvimento da pesquisa em sete grandes etapas. Foram obtidos três grandes resultados advindos da pesquisa: o método de referência MERGE-OI (diagramas de atividades, entradas, saídas, documentos e arquitetura); a validação do MERGE-OI de acordo com critérios de redução de incerteza e utilidade, bem como, o portfólio de oportunidades de inovação das cinco empresas em que se aplicou o método em campo. De forma mais ampla, esta pesquisa trouxe à tona a importância da integração entre as disciplinas de gestão de inovação, gestão de produtos e gestão de projetos.
In the context of business organizations, there is an on-going need of products and services launch on a regular basis due to time to market shortening which has been taking better choices in portfolio decisions on innovation opportunities. In particular, the issues of portfolio has been considered primarily in product and project management, which usually occurs late in the product development process (PDP) focused on reviewing and managing the portfolio of products and projects. Therefore, there is a gap between the generation of innovation opportunities and its implementation as products or projects, which affects organizations in several aspects as identifying and valuing their innovations, detecting opportunities in earlier stages such that they can be turned into innovations, balancing choices among several criteria including non-financial as well as driving portfolio decisions from strategy. In order to overcome these difficulties, since there are a lack of methods and techniques that addresses the portfolio more broadly, this research goal was to propose a reference method for portfolio generation for innovation opportunities (MERGE-OI), which has enabled business organizations to create and select a portfolio of innovation opportunities with more assertiveness, whatever the size and market segmentation. The MERGE-OI was applied in five representatives enterprises on three economic sectors: food and beverage, construction and electronics. A field survey allowed the method to be validated in terms of consistency and coherence. Regarding the research method, this research is primarily observational and content analysis, an the same methods were employed as well as techniques, which consolidated the research development in seven major steps: each of with two main phases: pre-analysis and exploration, consolidating a research corpus based on documentary and research techniques. The three main results obtained were: the reference method MERGE-OI (activity diagrams, inputs, outputs, documents and architecture), the validation of MERGE-OI according to criteria such as usefulness and precision, as well as the portfolio of innovation opportunities in the five enterprises in which MERGE-OI was applied. More broadly, this research has highlighted the importance of integration among subjects such as innovation management, product management and project management.

This dissertation describes a methodology for solving convex constraint problems using analog circuits. It demonstrates how this methodology can be used to design circuits that solve function-fitting problems through iterated gradient descent. In particular, it shows how to build a small circuit that can model a nonlinearity by observation, and predistort to compensate for this nonlinearity. The system fits into a broader effort to investigate non-traditional approaches to circuit design. First, it breaks the traditional input-output abstraction barrier; all ports are bidirectional. Second, it uses a different methodology for proving system stability with local rather than global properties. Such stability arguments can be scaled to much more complex systems than traditional stability criteria.

We have implemented a segment of an RF transmitter signal chain in discrete components using bipolar transistors. We formulated both a broadband amplifier and mixer as mathematical programs (MP) and extracted Pareto-optimal (PO) [1-3] tradeoff surfaces. Abstracting these PO surfaces in place of the blocks at the system level, we have demonstrated a new hierarchical system design methodology. Furthermore, the optimization, simulation, and measured results are consistent at all levels of hierarchy.

The work for this thesis was performed at Honeywell in the Automation and Control Solutions (ACS) division. The project focuses on ACS's manufacturing strategy regarding its global supply chain design, primarily discussing the manufacturing growth opportunities available in emerging regions. Honeywell ACS's current methodology for the development of a long-term manufacturing strategy is based on growth and total cost reduction objectives. In order to comprehend the total cost of the manufacturing strategy, considerations such as inventory, logistics and duties, outsourcing and material sourcing are evaluated. The project also considers a factory's geographical location and ACS's year-by-year implementation plan. An outcome of this Honeywell project and the basis of this thesis is the development of a general supply chain design and optimization methodology that utilizes three analytical tools (Country Selection Framework, Total Cost Model and Implementation Plan Process) that are capable of validating the supply chain design of any company. The analytical tools can be used to verify key strategic supply chain decisions or to create a baseline manufacturing strategy. The following results can be determined using this supply chain design methodology: Determine an appropriate operating region for current or future business needs; Evaluate the feasibility of factory relocation projects by considering all relevant costs; Evaluate the cost implications of the supply chain structure by considering logistics, inventory and material sourcing costs; Understand the impact of outsourcing on the manufacturing strategy; Recommend a year-by-year implementation plan in the case of multiple projects and limited capital resources.

Para garantir que uma pesquisa seja reconhecida como sólida e potencialmente relevante, tanto pelo campo acadêmico quanto pela sociedade em geral, ela deve demonstrar que foi desenvolvida com rigor e que é passível de debate e verificação. É neste âmbito que um método de pesquisa robusto se torna imprescindível para o sucesso na condução de um estudo. Este estudo busca contribuir para a comunidade de Engenharia de Produção argumentando pela necessidade de adotar-se um método de pesquisa centrado na evolução de uma “Ciência do Projeto” (Design Science), evidenciando seu sentido e suas formas de operacionalização. Para desenvolvimento deste estudo utilizou-se uma abordagem metodológica teórico-conceitual fundamentada em ampla revisão da literatura. A partir da revisão da literatura, foi possível verificar que os conceitos da proposta metodológica associada à pesquisa em Design Science, são pertinentes e aplicáveis à Engenharia de Produção. O trabalho apresenta um histórico conceitual a respeito da Design Science e da Design Science Research, a importância da definição das Classes de Problemas e dos Artefatos gerados no âmbito da pesquisa, e os principais passos para operacionalizar a Design Science Research. Para aprofundar o entendimento da pauta em questão, o trabalho também propõe comparações e análises sobre a Design Science e a sua relação com as ciências tradicionais. Ao final, o estudo busca apresentar alguns cuidados para a utilização e validação da Design Science Research.
To ensure that research is recognized as potentially relevant and solid, by both academic field and society in general, it must demonstrate that it was developed with rigor and is liable to debate and verification. It is in this context that a robust research method becomes essential to successfully conduct a study. This study seeks to contribute with the Production Engineering community debating the need to adopt a method of research focused on the evolution of Design Science, showing its meaning and its ways of operation. For this study was used an approach based on theoretical and conceptual extensive literature review. From the literature review, was possible to assert that the concepts associated with the proposed methodological research on Design Science are relevant and applicable to Production Engineering. This dissertation presents a conceptual history about the Design Science and Design Science Research, the importance of defining the Classes of Problems and Artifacts generated from a research, and key steps to operationalize the Design Science Research. To deepen the understanding of the staff concerned, this study also proposes comparisons and analyzes on the Design Science and its relationship with the traditional sciences. Finally, the study discusses some attenttion points for the use and validation of Design Science Research.

Abstract:

Formal methods have been proposed as a means of expediting the creation of reliable software. The use of formal methods allows for clear and unequivocal specification of a system's design, and makes possible a form of prototyping that allows for formal validation against system requirements. However, the adoption of formal methods by industry has so far been slow. It is proposed that one of the obstacles to the adoption of formal methods is the difficulty of bridging the gap between a formally-specified system and a working implementation. If this gap is too wide, the advantages of formal specification will be lost in the transition to implementation. The methodology described in this thesis attempts to close this gap by demonstrating how a system may be described using LOTOS (Language Of Temporally-Ordered Specifications) and validated against requirements using two techniques: composition with agent scenarios and temporal logic model checking. The methodology then allows for the derivation of a model in the ROOM (Real-Time Object-Oriented Modelling) notation, which may be automatically converted to an implementation in the C++ programming language. The methodology is illustrated with two small case studies. The first is the GPRS Tunnelling Protocol, used for transmitting protocol data units within the network of the General Packet Radio Service. The second study concerns authentication of users of the POP3 Internet mail protocol and demonstrates inheritance in LOTOS. Together, these case studies illustrate the salient points of the design methodology.

Full text

Abstract:

View John Huân Vũ's thesis presentation at http://youtu.be/y3bzNmkTr-c. In 2001, the ACM and IEEE Computing Curriculum stated that it was necessary to address "the need to develop implementation models that are international in scope and could be practiced in universities around the world." With increasing connectivity through the internet, the move towards a global economy and growing use of technology places software internationalization as a more important concern for developers. However, there has been a "clear shortage in terms of numbers of trained persons applying for entry-level positions" in this area. Eric Brechner, Director of Microsoft Development Training, suggested five new courses to add to the computer science curriculum due to the growing "gap between what college graduates in any field are taught and what they need to know to work in industry." He concludes that "globalization and accessibility should be part of any course of introductory programming," stating: A course on globalization and accessibility is long overdue on college campuses. It is embarrassing to take graduates from a college with a diverse student population and have to teach them how to write software for a diverse set of customers. This should be part of introductory software development. Anything less is insulting to students, their family, and the peoples of the world. There is very little research into how the subject of software internationalization should be taught to meet the major requirements of the industry. The research question of the thesis is thus, "Is there a framework for software internationalization that has been validated against industry requirements?" The answer is no. The framework "would promote communication between academia and industry ... that could serve as a common reference point in discussions." Since no such framework for software internationalization currently exists, one will be developed here. The contribution of this thesis includes a provisional framework to prepare graduates to internationalize software and a validation of the framework against industry requirements. The requirement of this framework is to provide a portable and standardized set of requirements for computer science and software engineering programs to teach future graduates.

Full text

Abstract:

For companies that develop and operate IT applications that process the personal data of customers and employees, a major problem is protecting these data and preventing privacy breaches. Failure to adequately address this problem can result in considerable damage to the company's reputation and finances, as well as negative effects for customers or employees (data subjects). To address this problem, we propose a methodology that systematically considers privacy issues by using a step-by-step privacy impact assessment (PIA). Existing PIA approaches cannot be applied easily because they are improperly structured or imprecise and lengthy. We argue that companies that employ our PIA can achieve "privacy-by-design", which is widely heralded by data protection authorities. In fact, the German Federal Office for Information Security (BSI) ratified the approach we present in this article for the technical field of RFID and published it as a guideline in November 2011. The contribution of the artefacts we created is twofold: First, we provide a formal problem representation structure for the analysis of privacy requirements. Second, we reduce the complexity of the privacy regulation landscape for practitioners who need to make privacy management decisions for their IT applications.

Full text

Abstract:

This thesis analyses the potential of the Deleuzian philosophical concept of 'expressionism' in accounting for and driving architectural design and research. An expansive literature considering the import of Deleuze in architecture is characterised by his simultaneous use in both poles of debates concerning Critical architecture at the centre of mainstream practice and as foundational source for minoritorian approaches to both design and research. Identifying this contemporary vacillation as a reiteration of traditional reductions of design to products or processes, and seeking development of an alternative trajectory, I propose the architectural project as an 'embodied' epistemological and ontological third term of an expressionist account of architectural design‐research. A series of critical encounters between philosophy and architecture exploring the accounts and practices of Robin Evans, Rem Koolhaas, Peter Eisenman and both professional and pedagogic design‐research undertaken by the author, articulate six key principles of a non‐representational, expressionist methodology for design and research in architecture. First 'expressionism' insists on a substantive distinction between nominal and real denying any essentialist component to architectural products or production. An encounter with Evans shows how architectural bodies both produce and are constituted by 'projective relations' external to architect, drawing and discipline. Koolhaas and Eisenman's divergent positions then demonstrate how projective distinctions are always embodied in two actual forms which select content and express an exterior. Fifth, a design for a non-human 'client' makes explicit the parallel and serial nature of processes of selection and projection. Sixth, community‐engaged design‐research demonstrates that active speculation towards positive change (outside of self and social habit) is a mechanism for the serial production of simultaneously ethical and aesthetical affective relationships. Extending and sharing the production of capabilities and powers of expression beyond the architect and architecture demonstrates the overarching principle of expressionism ‐ affirmative speculation is correlative with the creation of ethical joy.

Antidotes to this sedentary culture are required from both a prevention and treatment perspectives yet engaging adolescents in PA, one side of the energy balance equation, remains a challenge. 'Gaming culture' among youths might be an alternative approach and it is with this in mind that this research-through-design project explored how design practice and behaviour change theories can be combined to create, develop and refine game(s) to promote PA among adolescents aged 11-12. The iterative design process, supported by user-centred enquiries, used 'making' as the main method of enquiry and led to a contribution to knowledge. Design and knowledge in this research were interwoven: designing was the driver yet it is only through testing this design in context that understanding and knowledge could be verified, hence informing the next design development stage. A variety of design research techniques were used to explore, research, and understand situations and users, as well as to develop, review and evaluate prototypes. Various stakeholders such as design colleagues, friends, a family of users as well as 48 future end-users took part in this research. The iterations resulted in 'Boost Up!' which comprised a series of games utilising PA as a game currency. 'Boost Up!' explored how a 'blending experience' combining awareness and rewards via a gaming framework might promote repeated play to motivate an increase in PA behaviour. A final mixed-method study was used to evaluate the engagement of participants with 'Boost Up!' as well as its efficacy for promoting PA behaviour. Through testing the different versions of 'Boost Up!', a range of factors were identified for engaging adolescents (e.g. appropriation, instant feedback), which might be useful to those wanting to promote PA among this population, or even to monitor them. Furthermore, a new way to capture and report findings obtained when using a research-through-design methodology, using an Annotated Design History tehnique, was created. This approach may be of use to future design researchers. As a conclusion, the processes and techniques used in this research demonstrate the potential of using research-through-design methodology for health interventions.

Abstract:

There is a need for a systematic methodology that allows security architects to specialize standard security models (such as the NIST models) for use in e-commerce systems. This methodology must enable security architects to provide proper security measures for legitimate users and prescribe proper countermeasures against malicious users at system design time. In this thesis, we address this problem by providing a systematic methodology for deriving countermeasures design models for e-commerce systems based on the NIST security services model. We introduce and illustrate a new term, malicious user requirements, which denotes the features which if present enable malicious security attacks to succeed. Our methodology targets security by satisfying legitimate user requirements and blocking malicious user requirements at system design time. Furthermore, we evaluate our methodology by means of a case study. In particular, we derive four security countermeasures design models; namely authentication, authorization, access control enforcement, and transaction privacy models. (Abstract shortened by UMI.)

Abstract:

Statistical research can be more difficult to plan than other kinds of projects, since the research must adapt as knowledge is gained. This dissertation establishes a formal language and methodology for designing experimental research strategies with limited resources. It is a mathematically rigorous extension of a sequential and adaptive form of statistical research called response surface methodology. It uses sponsor-given information, conditions, and resource constraints to decompose an overall project into individual stages. At each stage, a "parent" decision-maker determines what design of experimentation to do for its stage of research, and adapts to the feedback from that research's potential "children", each of whom deal with a different possible state of knowledge resulting from the experimentation of the "parent". The research of this dissertation extends the real-world rigor of the statistical field of design of experiments to develop an deterministic, adaptive algorithm that produces deterministically generated, reproducible, testable, defendable, adaptive, resource-constrained multi-stage experimental schedules without having to spend physical resource.

Abstract:

Modern product design projects are often challenged by their interdisciplinary nature, increasing product complexity and time pressure. The challenge for product designers is to recall all relevant design aspects that are potentially applicable and important for the product to be designed at the right time. The negligence of certain design aspects may result in increased development costs and in inferior products. A recommended way to handle complexity in the design process is to work systematically, with checklists and guidelines offering a possibility to support product designers in this task. However, design guidelines that provide a comprehensive and generically content that support product designers holistically in their design projects are not readily available. Moreover, in-depth evaluations of the role, use, usefulness and usability of design guidelines are quite rare in the current literature. Therefore, the research study presented in this thesis sought to accomplish two tasks: the generation of a comprehensive set of generic and practically aimed product design guidelines in a paper-copy format that holistically supports product designers in their often complex design projects; and the evaluation of these generated design guidelines with the purpose of determining their role, use, usefulness and usability for product designers. A comprehensive and generically applicable set of product design guidelines in a ready-to-use paper-copy format that holistically provides in-depth information for the product design aspects that need to be considered during a design process was generated. Besides, a research study, using questionnaires and interviews, with product design students and professional product designers in New Zealand was carried out with the purpose of determining the role, use, usefulness and usability of the generated design guidelines for designers. As a consequence, valuable insights into the role of the guidelines as practitioners� design tool for professional designers and noteworthy findings about the role of the guidelines as educational tool for novice designers were obtained. The findings suggested that the use of guidelines as a tool in the design process is generally not very prevalent due to the designers� lack of knowledge about the benefits, location and accessibility of useful product design guidelines. Furthermore, it has been found that the designers used the generated guidelines sporadically and driven by their interest or demand in the design aspects applicable to their projects. In terms of the guidelines� usefulness it has been identified that the guidelines evaluated were generically applicable to different projects and provided a specific in-depth content. The guidelines have also been found to be quite useful as educational, planning, management and evaluation tool for novice and professional designers. However, in terms of the guidelines� usability, several problems were determined that made the generated guidelines too inefficient to be beneficial for the participants, especially for the professional designers. Accordingly, it has been concluded that a change of the guidelines� format into a digital interactive format, is likely to solve most of the identified problems and provide a useful and usable tool for product designers respectively.

Abstract:

This dissertation presents a case study of collaborative research through design with Floracaching, a gamified mobile application for citizen science biodiversity data collection. One contribution of this study is the articulation of collaborative research through design (CRtD), an approach that blends cooperative design approaches with the research through design methodology (RtD). Collaborative research through design is thus defined as an iterative process of cooperative design, where the collaborative vision of an ideal state is embedded in a design. Applying collaborative research through design with Floracaching illustrates how a number of cooperative techniques—especially contextual inquiry, prototyping, and focus groups—may be applied in a research through design setting. Four suggestions for collaborative research through design (recruit from a range of relevant backgrounds; take flexibility as a goal; enable independence and agency; and, choose techniques that support agreement or consensus) are offered to help others who wish to experiment with this new approach. Applying collaborative research through design to Floracaching yielded a new prototype of the application, accompanied by design annotations in the form of framing constructs for designing to support mobile, place-based citizen science activities. The prototype and framing constructs, which may inform other designers of similar citizen science technologies, are a second contribution of this research.

In recent years, many of the Department of Defense's major acquisition programs have experienced significant budget overruns and schedule delays. Closer examination of these programs reveals that in many cases, technologies were selected for these programs that did not meet expectations to enable the overall weapons system to achieve its intended goals. A methodology is proposed to extend systems analysis techniques to individual technologies to utilize a rational basis for technology selection. An example of this methodology is shown based on selecting technologies for the US Army's Active Protection System. The example demonstrates that use of this methodology can provide decision makers with a clear understanding of the effects choosing particular technologies.

Abstract:

This thesis consists of five chapters: 1.The Mechanical View, 2.Social Machines, 3.The FCC Auction Machine, 4.Self-Interested Knaves, and 5.Self-Interested but Sympathetic. In the first three chapters, I advance a methodological account of current design and engineering in economics and political science, which I call methodological mechanicism. It is not ontological or literal; it relies on a technological metaphor by describing market and state institutions as machines, and the human mind as consisting of a number of mechanisms. I introduce the Mechanical view on scientific theories as distinct from the Syntactic and the Semantic views. The electromagnetic theories from the nineteenth century are used to illustrate this view as well as the use of minimal and maximal analogies in model-building in normal and revolutionary science. The Mechanical view is extended to the social sciences, particularly to mechanism design theory and institutional design, using the International Monetary Fund, the NHS internal markets and the FCC auction as examples. Their blueprints are evaluated using criteria such as shielding and power for calculating joint effects as well as libertarian, dirigiste, egalitarian and inegalitarian properties; and the holistic and piecemeal engineering they adopt. Experimental parameter variation is introduced as a method complementing design. Any design assumes a particular moral psychology, so in chapters four and five I argue that the moral psychology of universal self-interest from Bernard Mandeville, and the related ideas on design and engineering, should be chosen over the moral psychology of self-interest, sympathy and sentiments of humanity from David Hume. Hume finds no solution for knavery in politics and civil society. He accepts egalitarianism as useful and consistent with utilitarian principles; however he rejects it because of some difficulties with its implementation. I show how those difficulties may be overcome, and I explain why his objections are unbalanced and not sufficiently justified.

Abstract:

HARDWARE TESTING is commonly used to check whether faults exist in a digital system. Much research has been devoted to the development of advanced hardware testing techniques and methods to support design for testability (DFT). However, most existing DFT methods deal only with testability issues at low abstraction levels, while new modelling and design techniques have been developed for design at high abstraction levels due to the increasing complexity of digital systems. The main objective of this thesis is to address test problems faced by the designer at the system level. Considering the testability issues at early design stages can reduce the test problems at lower abstraction levels and lead to the reduction of the total test cost. The objective is achieved by developing several new methods to help the designers to analyze the testability and improve it as well as to perform test scheduling and test access mechanism design. The developed methods have been integrated into a systematic methodology for the testing of system-on-chip. The methodology consists of several efficient techniques to support test scheduling, test access mechanism design, test set selection, test parallelization and test resource placement. An optimization strategy has also been developed which minimizes test application time and test access mechanism cost, while considering constraints on tests, power consumption and test resources. Several novel approaches to analyzing the testability of a system at behavioral level and register-transfer level have also been developed. Based on the analysis results, difficult-to-test parts of a design are identified and modified by transformations to improve testability of the whole system. Extensive experiments, based on benchmark examples and industrial designs, have been carried out to demonstrate the usefulness and efficiency of the proposed methodology and techniques. The experimental results show clearly the advantages of considering testability in the early design stages at the system level.

Abstract:

This thesis is concerned with the design and implementation stages of the development lifecycle of a class of systems known as hard real-time systems. Many of the existing methodologies are appropriate for meeting the functional requirements of this class of systems. However, it is proposed that these methodologies are not entirely appropriate for meeting the non-functional requirement of deadlines for work within these real-time systems. After discussing the concept of real-time systems and their characteristic requirements, this thesis proposes the use of a general transaction model of execution for the implementation of the system. Whereas traditional methodologies consider the system from the flow of data or control in the system, we consider the system from the viewpoint of the role of each shared data entity. A control dependency is implied between otherwise independent processes that make use of a shared data entity; our viewpoint is known as the data dependency viewpoint. This implied control dependency between independent processes, necessary to preserve the consistency of the entity in the face of concurrent access, is ignored during the design stages of other methodologies. In considering the role of each data entity, it is possible to generate other viewpoints, such as the dataflow through the processes, automatically. This however, is not considered in the work. This thesis describes a staged methodology for taking the requirements specification for a system and generating a design and implementation for that system. The methodology is intended to be more than a set of vague guidelines for implementation; a more rigid approach to the design and implementation stages is sought. The methodology begins by decomposing the system into more manageable units of processing. These units are known as tasks with a very low degree of coupling and high degree of cohesion. Following the system decomposition, the data dependency viewpoint is constructed; a descriptive notation and CASE tool support this viewpoint. From this viewpoint, implementation issues such as generating control flow; task and data allocation and hard real-time scheduling concerns, are addressed. A complete runtime environment to support the transaction model is described. This environment is hierarchical and can be adapted to many distributed implementations. Finally, the stages of the methodology are applied to a large example, a Ship Control System. Starting with a specification of the requirements, the methodology is applied to generate a design and implementation of the system.

Abstract:

A wide range of modeling and simulation packages have been applied to evaluate computer systems, telecommunication networks, and diverse environments in industry. The objective in utilizing simulation is to assess system designs prior to actual implementation. The approaches used to perform modeling range from programming with a specific simulation description language (the most common) to automation, using an icon-driven user interface. Flexibility, maintainability and acceptability are the main criteria used to make a choice. The objectives of the modeling and simulation environment are to automatically construct simulation models for the systems being designed, and to efficiently define the system performance measures. To meet these objectives, an environment called Performance Object-oriented modeling and Simulation Environment (POSE) has been created. In order to profile the knowledge involved in POSE, a knowledge representation scheme, System Entity Structure (SES) is adopted for efficient representation. POSE is organized into several layers such that the procedures of modeling can be set up in a hierarchical manner with the support of hierarchical model-based management. At the stage of defining system requirements, the structure of the Experimental Frame is applied to handle the system's traffic generation, performance data collection and computation. A methodology called Integrated performance Specification (IPS) is designed to facilitate model generation of the frame structure. At the system modeling level, elementary models are organized via combining the properties of a queuing model and the structure of Discrete EVent System Specification (DEVS) formalism. An overall system model is then constructed based upon the elementary models by applying the SM-Algo algorithm. Finally, the system models are integrated with the proper experimental frames in distributed and centralized execution modes to create integrated simulation models. An algorithm called MI-Algo assists the integration procedure. A window-based graphical front-end offers a simple and straightforward user interface to enhance the efficiency of POSE.

Abstract:

Distributed intelligence systems are starting to gain dominance in the field of large-scale complex systems. These systems are characterized by nonlinear behavior patterns that are only predicted through simulation-based engineering. In addition, the autonomy, intelligence, and reconfiguration capabilities required by certain systems introduce obstacles adding another layer of complexity. However, there exists no standard process for the design of such systems. This research presents a design methodology focusing on distributed control architectures while concurrently considering the systems design process. The methodology has two major components. First, it introduces a hybrid design process, based on the infusion of the control architecture and conceptual system design processes. The second component is the development of control architectures metamodel, placing a distinction between control configuration and control methods. This enables a standard representation of a wide spectrum of control architectures frameworks.
