Al, Yami H. M. A. "Decision making analysis for an integrated risk management framework of maritime container port infrastructure and transportation systems." Thesis, Liverpool John Moores University, 2017. http://researchonline.ljmu.ac.uk/6371/.
Full textAbstract:
This research proposes a risk management framework and develops generic risk-based decision-making, and risk-assessment models for dealing with potential Hazard Events (HEs) and risks associated with uncertainty for Operational Safety Performance (OSP) in container terminals and maritime ports. Three main sections are formulated in this study: Section 1: Risk Assessment, in the first phase, all HEs are identified through a literature review and human knowledge base and expertise. In the second phase, a Fuzzy Rule Base (FRB) is developed using the proportion method to assess the most significant HEs identified. The FRB leads to the development of a generic risk-based model incorporating the FRB and a Bayesian Network (BN) into a Fuzzy Rule Base Bayesian Network (FRBN) method using Hugin software to evaluate each HE individually and prioritise their specific risk estimations locally. The third phase demonstrated the FRBN method with a case study. The fourth phase concludes this section with a developed generic risk-based model incorporating FRBN and Evidential Reasoning to form an FRBER method using the Intelligence Decision System (IDS) software to evaluate all HEs aggregated collectively for their Risk Influence (RI) globally with a case study demonstration. In addition, a new sensitivity analysis method is developed to rank the HEs based on their True Risk Influence (TRI) considering their specific risk estimations locally and their RI globally. Section 2: Risk Models Simulations, the first phase explains the construction of the simulation model Bayesian Network Artificial Neural Networks (BNANNs), which is formed by applying Artificial Neural Networks (ANNs). In the second phase, the simulation model Evidential Reasoning Artificial Neural Networks (ERANNs) is constructed. The final phase in this section integrates the BNANNs and ERANNs that can predict the risk magnitude for HEs and provide a panoramic view on the risk inference in both perspectives, locally and globally. Section 3: Risk Control Options is the last link that finalises the risk management based methodology cycle in this study. The Analytical Hierarchal Process (AHP) method was used for determining the relative weights of all criteria identified in the first phase. The last phase develops a risk control options method by incorporating Fuzzy Logic (FL) and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to form an FTOPSIS method. The novelty of this research provides an effective risk management framework for OSP in container terminals and maritime ports. In addition, it provides an efficient safety prediction tool that can ease all the processes in the methods and techniques used with the risk management framework by applying the ANN concept to simulate the risk models.

Full textAbstract:
El trabajo de investigación desarrollado a continuación tiene como finalidad evidenciar que la implementación de los estándares y buenas prácticas recomendadas en la guía del PMBOK® 6ª edición, aplicando el enfoque del PMI, resulta útil para la implementación de obras marinas, como en el caso del Astillero Naval del Callao, generando un precedente en la bibliografía a consultar para el desarrollo de futuras obras de este tipo. A partir de la 6ª edición, el director de proyecto asume nuevos roles, y se convierte en el nexo entre la organización y el proyecto, para maximizar el aprovechamiento del beneficio que el proyecto genere para la organización. Este trabajo pretende ilustrar como en el caso de la dirección de proyectos de obras marinas se aplica este nuevo enfoque, identificando los beneficios que la organización desea obtener del proyecto y describiendo las características que el director de proyecto debe tener en cuenta para cumplir este nuevo rol.
En este trabajo se evidencia, entre otras cosas, la importancia de convocar y seleccionar proveedores especializados en obras acuáticas, así como contar con una supervisión especializada.
Este proyecto que se suma a la infraestructura portuaria del país, y su ejecución se convierte en referente para nuevos proyectos como el caso del Puerto San Martín o el Terminal Portuario Salaverry, los cuales se desarrollarán en los próximos años y requerirán no solamente de personal calificado, sino además de toda la información registrada de obras anteriores que puedan servir de base de lecciones aprendidas a futuro para una ejecución eficiente.The research work developed below has as purpose prove that the implementation of the standards and good practices recommended in the PMBOK® Guide 6th edition, applying the PMI approach, is useful for implementation of navy projects, as in the case of the Callao Shipyard Naval, generating a precedent in the bibliography to consult for the development of future projects of this type. Since the 6th edition, the project manager assumes new roles and becomes the nexus between the organization and the project, to maximize the use of the benefit that the project generates for the organization. This work aims to illustrate how this new approach is applied in the case of project management in navy projects, identifying the benefits than organization wishes to obtain from the project and describing the characteristics that the project manager must take into account in order to fulfill this new role. This paper demonstrates, among other things, the importance of calling and selecting specialized suppliers in waterworks, as well as having specialized supervision. This project that is added to the port infrastructure of the country, and its execution becomes a reference for new projects such as the case of Puerto San Martín or the Salaverry Port Terminal, which will be developed in the coming years and will require not only qualified personnel, but also all the registered information of previous works that can serve as a base of lessons learned in the future for an efficient execution.

As cidades brasileiras enfrentam graves problemas na construção e manutenção de suas infraestruturas, que comprometem a qualidade de vida da população. Geralmente, como é o caso das obras viárias e, mais particularmente, dos pavimentos, tratam-se de obras e serviços que necessitam de investimentos vultosos e que deveriam, portanto, ser corretamente dimensionadas, executadas e mantidas ao longo da vida em serviço. Este trabalho trata dos Sistemas de Gerência de Pavimentos Urbanos (SGPU), relatando experiência de implantação em uma cidade de médio porte (Anápolis-GO), apresentando todas as etapas e fases de implantação, as barreiras institucionais que tiveram de ser vencidas, o entrelaçamento entre as áreas técnica, jurídica, administrativa, ambiental e política, os resultados e benefícios obtidos com a implantação do SGPU e as principais funções e utilidades, que incluem não só a otimização do planejamento das atividades de manutenção e reabilitação dos pavimentos, mas, também, o auxílio à prefeitura municipal na busca de recursos junto ao Governo Federal ou a outros órgãos de financiamento. Os resultados obtidos com a implantação do SGPU-Anápolis foram positivos, podendo-se destacar o auxílio em processo licitatório para contratação de obras de manutenção preventiva, sendo que, anteriormente, as opções se restringiam tão somente aos tapa-buracos e recapeamentos sem dimensionamento estrutural, o estímulo ao desenvolvimento da área de pavimentação junto aos cursos de Engenharia Civil existentes na cidade, com contratação de estagiários para atuação em todas as etapas, incentivo à implantação de uma gerência de infraestrutura urbana, com a compatibilização de todos os setores que se utilizam do sistema viário (transporte público, água, esgoto, drenagem, iluminação pública, telefonia, gás, energia elétrica, meio-fio, sarjetas, calçadas etc.), preparação de equipe para utilização de uma base comum de dados georreferenciados para a gerência da infraestrutura urbana, inclusive com contratação de estagiários de arquitetura de cursos existentes na cidade e região, formação e aperfeiçoamento técnico dos gestores públicos e tomadores de decisão em geral e, finalmente, desenvolvimento de um exemplo de processo sinérgico envolvendo a universidade, a iniciativa privada e a administração pública.Brazilian cities face serious problems in the construction and maintenance of its infrastructure, which affect the quality of life. Generally, as in the case of road works and, more particularly, the pavements, these are works and services that require huge investments and should therefore be properly designed, built and maintained throughout the service life. This work deals with the Urban Pavements Management Systems, reporting deployment experience in a medium-sized city (Anapolis-GO), showing all the stages and phases of implementation, institutional barriers that had to be overcome, the entanglement between areas (technical, legal, administrative, environmental and political), the results and benefits obtained with the implementation and the main functions and utilities, which include not only the optimal planning of pavement maintenance and rehabilitation activities, but also aid to the municipal government in seeking funds from the federal government or other funding agencies. The results obtained three years after the implementation of SGPU-Anapolis are very positive, and it can be highlight the aid in the bidding process for preventive maintenance works, since the previous options were limited solely to patching and underdesigned overlays, stimulating the development of the paving area along the courses of Civil Engineering in the city, with hiring interns to work in all stages, encouraging the establishment of a management of urban infrastructures, with the compatibility of all sectors that use the roadway system (public transportation, water, sewage, drainage, street lighting, telephone, gas, electric, curbs, gutters, sidewalks etc.), preparation of staff for the use of a common set of georeferenced data for management of urban infrastructure, including hiring interns of architecture courses in the city and nearby town, training and technical improvement of public managers and decision makers in general, and finally, development of an example of synergistic process involving the university , the private sector and public administration.

This thesis discusses the different components required to build and design a prototype for the Intelligent Parking Management (IPM) infrastructure. Different aspects of the hardware and software components used to build the prototype is also discussed in the thesis along with discussion of business and marketing strategies for the viability of the solution for commercial use. A prototype solution was built using hardware and software components. The prototype was tested for real-time parking meter availability information for both general web customers and smart device users such as PDA with wireless access and Smart Phone mobile devices using 3G technologies. The tests were conducted in a controlled environment with simulation data for real parking meters. The IPM prototype solution infrastructure built was able to provide real-time parking information. The information was accessible via the Internet through standard browsers and 3G enable Smart Phones. The integration between the hardware and software components and the IPM infrastructure design prototype was enabled through various technologies such as Microsoft .NET platform, Microsoft SQL Server 2000, Microsoft Mobile Internet toolkit, DTS, ASP.NET and ADO.NET. The thesis discusses these technologies and their interconnectivity within the IPM infrastructure.

Full textAbstract:
Concerning management of smoke following an accidental fire within a building it is desirable to be able to estimate, within some understood, acceptable magnitude of error, the volume of smoke resulting from the combustion process of a predefined design fire scenario. Traditionally a range of first principle-based and empirically derived correlations are used to estimate the mass flow of smoke at a height of interest within the fire plume and are based upon the understanding that the mass flow of smoke at that height is a function only of the gravitational vector within the fire system, that is to say, that induced by the pressure differential between the naturally occurring hot plume gases and the surrounding quiescent bulk fluid. The statement that the fire plume is surrounded by a quiescent bulk fluid is in itself a significant simplification and is a key assumption required to facilitate the relative simplicity of the Froude-based entrainment correlations. It is of course quite intuitive to imagine that in real accidental fire scenarios in the built environment and across an array modern infrastructure, rarely does a fire exist submerged in a passive, quiescent atmosphere. This disconnect between the natural mechanics of the buoyant fire mechanism and the surrounding fluid in which it exists was necessary when the problem of entrainment by the fire plume was first described in the mainstream engineering literature around the middle of the twentieth century. Some 25 years later as ideal entrainment mechanics were beginning to be discussed specifically for application by a field of engineering in its infancy, a few researchers in the field of fire safety engineering published data that suggested that the addition of a relatively weak cross flow to the fire plume could have a significant impact upon the rate of air entrained by the plume, and by extension, the resultant smoke mass flow rate. The data published appeared more as a brief comment on an observation made during testing. It would be easily missed, nuzzled away in the middle of a lengthy doctoral thesis. Said thesis however happens to be one of the primary pieces of work that may be cited in reference to the formulation of perhaps the best known form of the axis-symmetric fire plume entrainment correlation, that of the so-called Zukoski correlation. It is perhaps curious then that the mention of a 3-fold increase in entrainment measurements following “small disturbances” in the atmosphere during the experimental work has seemingly been ignored by researchers, probably never-learned by students, and apparently forgotten by an industry. In a fire situation smoke can limit way-finding ability, severely irritate critical soft tissue like the eyes, trachea and oesophagus, impair cognitive function, contribute to significant property damage, facilitate the transfer of heat and carcinogens to locations remote to the fire source and it is well understood that most deaths due to fire are caused by asphyxiation following smoke inhalation. Significant portions of project budgets may be spent on designing, validating, installing and maintaining smoke management systems including the use of active systems such as extraction and pressurisation, passive curtains/reservoirs and detection such aspirating, video and beam detectors. Turbulent atmospheres may arise in any manner of situations such as modern buildings with large open spaces (airports, museums), hotel foyers and those with atriums spanning many floors, hangars and storage facilities/warehouses. Strong winds are normal on offshore oil platforms, outside the window on most floors of super-tall buildings or quite simply, anywhere on a blustery day. In specific cases the extraction systems designed to remove smoke and even normal HVAC systems can cause substantial air flow over large areas. In fact, a simple compartment with an uneven distribution of ventilation points (windows/doorways) has been shown to result in a directional fire flow that results in a significantly tilted flame, essentially inducing a cross flow scenario using the natural fire alone. With the coming-of-age of computational fluid dynamics models which are now a standard tool in all commercial fire engineering design offices, and probably in every smoke modelling report, it might be argued that there is little need to revisit the hand calculations from the ground up. Accepting, however, that a cross flow may increase the rate of entrainment of a fire plume and that this challenges the fundamental principles that all previous entrainment correlation knowledge is based on, and demonstrating the outcome (in terms of plume mass flow rate) with the use of a computational model, is an entirely different thing to understanding why this happens. Smoke management is one of the core design criteria, or questions at least, in practically all fire engineering design projects. In the literature there appears to be; no work quantitatively investigating cross flow fire plume entrainment rates; no work qualitatively describing the behaviour of the flame / fire plume under the influence of a cross flow (with respect to entrainment); and certainly no work framing this paradigm in the theoretical or practical context of the impact upon modern smoke control systems. This work aims to venture into these areas in the hope of beginning to piece together the overarching story of entrainment in the cross flow fire plume. The fundamental paradigm here is the addition of cross flow inertia (a horizontal pressure differential) to the axis-symmetric case where buoyancy (a zero initial momentum, vertical pressure differential) is the sole driver of the fluid flow system. How these flows then interact in a mixed convection sequence is investigated and described in terms that are useful for practical consideration by fire safety engineers. It is hoped that the concepts postulated and the questions raised will inspire further investigation into this poorly understood, but fundamental fire safety problem.

Rail Control Solutions (RCS) is one division of Bombardier Transportation, aimed at optimising flow of trains. OPTIFLO is a new solution package within RCS, providing services and solutions to address challenges in modern railway infrastructures worldwide. Infrastructure Management (IM) Service is a significant sub-module under OPTIFLO, performing monitoring and diagnostic functionalities for each impacted system or component in railway signalling systems to continuously improve safety, reliability and availability. Requirement management is a significant stage while dealing with engineering problems. In this master thesis project, three modules in railway signalling scope are focused, including system level Infrastructure Management, sub-system level Maintenance and Diagnostic Centre (MDC) and sub-system level Remote Sensor Unit (RSU). For each part, requirement managements have been implemented, referring to CENELEC standards where necessary. The work starts with the draft Requirement Specification for IM and then identify the requirements related to diagnostics and performance in each sub-system. Both links between the requirements in different modules and links between the requirements and their test cases are built from the requirement management tool DOORS to realize verification and validation following the system engineering process. Finally, the standard documentations "System Requirement Specification" for each impacted module that are mostly concerned in the thesis have been released.Rail Control Solutions (RCS) är en del av Bombardier Transportation, som syftar till att optimera flödet av tåg.

Full textAbstract:
Over the last decade, advances in technology together with the increasing use of the Internet for everyday tasks, are causing profound changes in end-users, as well as in businesses and technology providers. The widespread adoption of high-speed and ubiquitous Internet access, is also changing the way users interact with Web applications and their expectations in terms of Quality-of-Service (QoS) and User eXperience (UX). Recently, Cloud computing has been rapidly adopted to host and manage Web applications, due to its inherent cost effectiveness and on-demand scaling of infrastructures. However, system administrators still need to make manual decisions about the parameters that affect the business results of their applications ie., setting QoS targets and defining metrics for scaling the number of servers during the day. Therefore, understanding the workload and user behavior ¿the demand, poses new challenges for capacity planning and scalability ¿the supply, and ultimately for the success of a Web site.
This thesis contributes to the current state-of-art of Web infrastructure management by providing: i) a methodology for predicting Web session revenue; ii) a methodology to determine high response time effect on sales; and iii) a policy for profit-aware resource management, that relates server capacity, to QoS, and sales. The approach leverages Machine Learning (ML) techniques on custom, real-life datasets from an Ecommerce retailer featuring popular Web applications. Where the experimentation shows how user behavior and server performance models can be built from offline information, to determine how demand and supply relations work as resources are consumed. Producing in this way, economical metrics that are consumed by profit-aware policies, that allow the self-configuration of cloud infrastructures to an optimal number of servers under a variety of conditions. While at the same time, the thesis, provides several insights applicable for improving Autonomic infrastructure management and the profitability of Ecommerce applications.Durante la última década, avances en tecnología junto al incremento de uso de Internet, están causando cambios en los usuarios finales, así como también a las empresas y proveedores de tecnología. La adopción masiva del acceso ubicuo a Internet de alta velocidad, crea cambios en la forma de interacción con las aplicaciones Web y en las expectativas de los usuarios en relación de calidad de servicio (QoS) y experiencia de usuario (UX) ofrecidas. Recientemente, el modelo de computación Cloud ha sido adoptado rápidamente para albergar y gestionar aplicaciones Web, debido a su inherente efectividad en costos y servidores bajo demanda. Sin embargo, los administradores de sistema aún tienen que tomar decisiones manuales con respecto a los parámetros de ejecución que afectan a los resultados de negocio p.ej. definir objetivos de QoS y métricas para escalar en número de servidores. Por estos motivos, entender la carga y el comportamiento de usuario (la demanda), pone nuevos desafíos a la planificación de capacidad y escalabilidad (el suministro), y finalmente el éxito de un sitio Web.Esta tesis contribuye al estado del arte actual en gestión de infraestructuras Web presentado: i) una metodología para predecir los beneficios de una sesión Web; ii) una metodología para determinar el efecto de tiempos de respuesta altos en las ventas; y iii) una política para la gestión de recursos basada en beneficios, al relacionar la capacidad de los servidores, QoS, y ventas. La propuesta se basa en aplicar técnicas Machine Learning (ML) a fuentes de datos de producción de un proveedor de Ecommerce, que ofrece aplicaciones Web populares. Donde los experimentos realizados muestran cómo modelos de comportamiento de usuario y de rendimiento de servidor pueden obtenerse de datos históricos; con el fin de determinar la relación entre la demanda y el suministro, según se utilizan los recursos. Produciendo así, métricas económicas que son luego aplicadas en políticas basadas en beneficios, para permitir la auto-configuración de infraestructuras Cloud a un número adecuado de servidores. Mientras que al mismo tiempo, la tesis provee información relevante para mejorar la gestión de infraestructuras Web de forma autónoma y aumentar los beneficios en aplicaciones de Ecommerce.

In urban planning and design, natural systems are a key element of explorations about how to design for sustainability. As part of these efforts, academics and practitioners have also begun to explore the ways in which the utilization of natural systems can and should change our approach to the design and function of urban areas and of infrastructure itself. As an entry point to explore the topic, this thesis focuses on stormwater management as one basic building block or fundamental component of multipurpose infrastructure development. An increasing number of cities will seek to implement green infrastructure approaches or stormwater best management practices (BMPs) in response to new regulation, desires to improve urban quality of life, and changes in attitudes about sustainability and climate change. However, a variety of urban conditions exist within and between cities, and it is therefore necessary to consider the range of possibilities for designing and implementing green infrastructure strategies in a range of built environments. At the same time, there is also the need to address other environmental, social, and cultural goals, such as creating assets from vacant land, improving the public realm, and creating connectivity through neighborhoods. This creates opportunities to develop multipurpose infrastructure projects that utilize natural systems to address multiple objectives. San Francisco, California; Lincoln, Nebraska; and Cleveland, Ohio represent three different types of urban conditions and serve as test locations to identify the factors that affect the development of multipurpose infrastructure. San Francisco has a dense urban environment, Lincoln expects continued horizontal growth through subdivisions, and Cleveland's decline in population has created a condition of vacancy throughout the city. These conditions present a range of constraints and opportunities and shape the planning, design, and implementation of multipurpose infrastructure based on stormwater management. As a result, they lead to three methods or approaches for planning and design of multipurpose infrastructure: the retrofitting city, the preemptive city, and the repurposing city. These three approaches highlight how stormwater management can serve as a basis to develop multipurpose infrastructure systems that function at a range of scales, serve multiples purposes and create additional value for communities.

Full textAbstract:
Infrastructure organisations are operating in an increasingly challenging business environment as a result of globalisation, privatisation and deregulation. Under such circumstances, asset managers need to manage their infrastructure assets effectively in order to contribute to the overall performance of their organisation. In an external business environment that is constantly changing, extant literature on strategic management advocates a resourced--�]based view (RBV) approach that focuses on factors internal to the organisation such as resources and capabilities to sustain organisation performance. The aim of this study is to explore the core capabilities needed in the management of infrastructure assets. Using a multiple case study research strategy focusing on transport infrastructure, this research firstly examines the goals of infrastructure asset management and their alignment with broader corporate goals of an infrastructure organisation. It then examines the strategic infrastructure asset management processes that are needed to achieve these goals. The core capabilities that can support the strategic infrastructure asset management processes are then identified. This research produced a number of findings. First, it provided empirical evidence that asset management goals are being pursued with the aim of supporting the broader business goals of infrastructure organisations. Second, through synthesising the key asset management processes deemed necessary to achieve the asset management goals, a strategic infrastructure asset management model is proposed. Third, it identified five core capabilities namely stakeholder connectivity, cross-functional, relational, technology absorptive and integrated information management capability as central to executing the strategic infrastructure asset management processes well. These findings culminate in the development of a capability model to improve the performance of infrastructure assets.

The following research builds on the existing project management success and critical success factor research by focusing on the social mechanisms used by project managers and project teams to achieve success. Through analysis of previous literature five criteria for success are determined and the critical success factor themes of personnel and communication emerge. Study One uses semi-structured interviews with ten current or former construction project managers to develop a conceptual model of six antecedents to the previously identified critical success factor themes. The unit of measure is the project and not the project manager which allowed for ten interviews to provide insights into twenty projects, the ten most successful and the ten least successful of the interviewees careers. Those interviews provided six constructs or antecedents that lead to effective communication and project personnel. The personnel constructs are; planning, choosing, and retaining. The communication constructs are frequency, understanding, and inclusivity. Study Two uses semi-structured interviews with twenty current or former construction project managers to determine the causal social mechanisms that lead from the antecedents to the critical success factor themes. Through recording, transcribing, coding, and analyzing the interviewee’s responses project managers and project teams use similar mechanisms to achieve the critical success factor themes. Knowing those mechanisms will benefit practicing project managers.

O presente trabalho tem por objetivo analisar como o ambiente institucional pode influenciar a realização dos investimentos em infraestrutura portuária, tomando como referência o Estado da Bahia. Foi utilizado como pano de fundo teórico a teoria institucional, a partir de uma leitura sobre as estruturas de governança utilizadas na provisão de serviços portuários. Foram analisados os aspectos regulatórios e identificadas as principais instituições e organizações que atuam no subsetor. Posteriormente, a partir de observação participante do autor, análise documental e entrevistas realizadas junto a atores relevantes envolvidos com o sistema portuário baiano, são apresentados os principais impactos do atual modelo de governança na implementação dos investimentos necessários ao desenvolvimento do subsetor. O que se pode perceber é que o modelo de governança hoje existente precisa de muitos ajustes. A omissão, a falta de iniciativa e o baixo desempenho por parte dos agentes responsáveis pela gestão do subsetor são apontados, pelos atores envolvidos, como os principais fatores do não atendimento às demandas inerentes ao melhor desempenho do subsetor portuário. Este conjunto de entrevistas e a análise teórica e documental apresentam não só um número significativo de entraves, mas também trazem à tona propostas para equacionar estes problemas, que merecem, no mínimo, uma discussão mais aprofundada.

Between 1999 and 2007, a series of infrastructure improvements were completed at the Port of Brunswick, Georgia, in order to increase cargo capacity at the port. This paper looks at the port for indications of economic development generated through this infrastructure investment. Infrastructure improvements impact Georgia's economy by making additional cargo throughput possible through the Port of Brunswick by enabling larger cargo vessels to access the port. Additional cargo traffic generates economic opportunity by creating jobs to handle, move, sell and produce this new cargo volume. This analysis investigates what the infrastructure improvements accomplished in terms of improved port operations, what measurable impact they have had on throughput at the port, and associates these changes with economic gains for the State of Georgia.
Primary research is used to determine exactly what infrastructure projects were undertaken and how each impacted the port in terms of operations, actual new business and potential growth. This data on increased cargo volumes, realized and potential, is translated into statewide economic impact through existing data on how port traffic affects economic indicators such as output, gross state product, income and employment.
The infrastructure improvements created measurable gains at the Port of Brunswick in terms of increased cargo volumes and new business contracts. The effect through the State of Georgia is much greater when economic multipliers are considered.

Infrastructure such as transportation networks improves the condition of everyday lives by facilitating public services and systems necessary for economic activity and growth. However, constructing and maintaining transportation infrastructure poses safety hazards and risks to those working at the sharp end, leading to serious injuries and fatalities. Therefore, the identification of hazards and managing the risks they create is integral towards continually improving safety levels in Infrastructure Management. This work seeks to fully understand this problem and highlight past, present and future issues concerning safety in a comprehensive literature review. A decision support tool is proposed to improve the safety of transportation workers by facilitating hazard identification and management of associated control measures. This Tool facilitates the extraction of safety knowledge from real paper-based safety documents, capturing existing worker’s knowledge and experiences from industrial ‘corporate memory’. The Tool suggests the most appropriate control measures for new scenarios based on existing knowledge from previous work tasks. This is achieved by classifying work tasks using a new method based on unilateral UK legislation (Reporting of Injuries, Diseases and Dangerous Occurrences (1995) Regulations) and the innovative use of Artificial Intelligence method Case Based Reasoning. Case Based Reasoning (CBR) allows transparency in the Tool processes and has many benefits over other safety tools which may suffer from ‘black box’ stigmatism. The Tool is populated with knowledge extracted from a real transportation project and is hosted via the internet (www. Total-Safety.com). The end product of the Tool is the generation of bespoke method statements detailing appropriate control measures. These generated paper documents are shown to have financial and quality control benefits over traditional method statements. The Tool has undergone testing and analysis and is shown to be robust. Finally, the overall conclusions and opportunities for further research are presented and progress of the work against each of the five research objectives is assessed.

Three-tiered enterprise GIS architecture offers a robust, efficient, and secure mechanism as a potential revolution to disaster management systems. This paper addresses the severe limitations of existing disaster management systems and proposes an integrated management information system as an alternative. The value of such a 3-tiered enterprise GIS is its ability to function as reliable and efficient system during a disaster. Issues related to data storage, handling, timely distribution of processing power, efficient retrieval and dissemination of information, and data security against unauthorized access have to addressed using the state-of-the-art technology. Recent advancements in (1) standardized data specification, (2) middleware services, and (3) web-enabled distributed computing provide key resources to design and implement a tool of unprecedented flexibility and capacity for disaster management. This paper presents the critical details of such a system.

Building ML-based workflows in the real world is a trial-and-error, iterative process where an ML developer builds tens to hundreds of workflows before arriving at one that meets some task-specific acceptance criteria. This iterative process of workflow building is laborious for several reasons including the large variety of available ML models, the time required to train the workflow, difficulty keeping track of workflows built during the modeling process, and the time required for debugging trained workflows. In this thesis, we are primarily interested in two problems with the repetitive modeling process: first, how to manage ML-based workflows generated over multiple iterations of the modeling process, and second, how to efficiently debug or diagnose trained ML-based workflows. In this work, we study these questions from a systems perspective and propose novel software systems and techniques to address them. Specifically, our contributions are: 1. We propose MODELDB, a system to track provenance and performance of ML-based workflows. 2. We propose MISTIQUE, a system to store ML-based workflow intermediates in order to speed up model debugging tasks, and 3. We provide examples of new diagnostic techniques that can be designed using the data in MISTIQUE.

Full textAbstract:
Owners of infrastructure assets have responsibility for the management of a diverse portfolio of civil engineering assets. These assets make up the foundations of modern society and are arguably pivotal in the economic growth and wellbeing of a nation. It is of no surprise therefore, that asset management business practises have risen in popularity as the UK’s infrastructure asset base continues to grow and inevitably ages with time. In the context of water and waste water infrastructure assets, which communities rely upon for health, economy and environmental sustainability, it is widely acknowledged that these assets have historically suffered from underinvestment. Whilst funding shortfalls have been evidenced historically, through the inadequacy of infrastructure to meet the needs and challenges of the past, it is of great concern that infrastructure expenditure is reducing in real terms as a result of the global financial crisis. This is leading to a widening funding gap between the available and the required finances for infrastructure investment which is further compounded by natural phenomena and human behaviours, i.e., climate change, population growth and urbanisation. To further intensify the problem, asset planning and management in the water industry is considered a complex and challenging discipline because of high interdependencies and the vast quantity of assets themselves. In acknowledgement of this global position, this thesis seeks to address some of the key challenges faced by utility companies in the adoption of asset management best practice across water and waste water assets, namely: • Operational decision making - the efficient and effective specification of least-cost rehabilitation programmes from condition information that ensure behavioural alignment with an organisations strategic objectives. • Tactical decision making - achieving risk based asset level inspection prioritisation that considers serviceability performance, for two particularly challenging asset groups: i.) High value - low volume assets and ii). Low value - high volume buried infrastructure. • Strategic decision making - identifying optimal long-term investment plans and asset management policies for assets that have previously not benefited from such technological advancements. To improve upon operational decision making, the author capitalises on the availability of condition inspection information for buried sewerage infrastructure by applying advanced optimisation techniques to help form an environment where the decision makers is presented with an array of optimal rehabilitation solutions. The trade-off curve that is presented uniquely evaluates solutions for the benefits they offer in-terms of: condition improvement, cost and operational performance. A financially favourable comparison (up to 45% saving) is drawn between the optimisation results which are automatically generated by the model and those that have been developed manually by experienced engineers in a ‘real world’ case study. However, it could be argued that the greatest benefit arises from the trade curve of feasible solutions which are presented to the decision maker across a range of investment levels. In recognition that tactical and strategic decision making have been the focus of a substantial amount of research for commonly found infrastructure assets, i.e., public sewers and water mains, a focus has been placed on improving upon and adopting best practise across infrastructure assets which have not previously benefited from the technological developments across these decision making levels. Firstly, a methodology for translating standardised condition inspection information into more meaningful reliability scores, to support risk based planning and decision making, is presented for service reservoirs. A service reservoir can be regarded as high value- low volume infrastructure asset and would typically have its condition evaluated between 1 (poor) to 5 (good). A case study demonstrates how this new reliability scoring mechanism has been successfully applied during a typical structural condition survey. The output from this process is a fully document reliability assessment for each component of the service reservoir. The output can be aggregated to provide an overall reliability assessment for the structure and/or used to target specific remedial works to troublesome components. Secondly, two methodologies are presented which address the fact that high volume – low value infrastructure assets across both the water distribution and wastewater collection networks, are typically less well understood and often sub-optimally managed in comparison to more critical or higher value assets. 1. A methodology has been developed to help UK water companies overcome the recent legislative changes associated with Section105A of the Water Act; which has transferred ownership of the private sewer network to UK water companies. The new methodology which has been developed, has allowed one of the UK’s water and sewerage companies to initiate a proactive asset management programme with the aim of addressing the deteriorating condition of these assets whilst also tackling their associated serviceability performance. Initially, a number of GIS tools are used to provide an estimate of the likely extent of the transferred network before a well-established public sewer deterioration model is used to predict the condition and operational performance of these S105A assets over time. 2. A novel deterioration modelling framework is developed by coupling the latest geospatial technologies with statistical deterioration modelling techniques. The modelling framework is specifically applied to small diameter water distribution assets (25-50mm diameter), known as communication pipes, which connect individual properties to the water distribution mains. Reliability curves are developed from failure data provided by two UK based Water Companies that have captured specific communication pipe failure records since 2001. The deterioration modelling curves and supporting data are compared and contrasted to demonstrate the robustness of this modelling approach, which is shown to be capable of modelling failure rates to a high degree of accuracy. This was validated by comparing the predicted number of failures against three years of failure data not used during the model building process. The yearly failure counts were predicted to within +/-5% accuracy and the overall cumulative modelled failure count at the end of 2014 was predicted within 1%. To conclude, the successful deterioration modelling tools for communication pipes are explored further, via the development of a strategic whole life cost optimisation framework for these assets. The outputs from the previous geospatial mapping tool are used alongside the calibrated Weibull deterioration curves to drive a whole life cost and performance analysis. Against this improved understanding of whole life costs, an optimisation algorithm is used to evaluate the trade-off between whole life costs (totex) and the prevention of future asset failures (serviceability). The model successfully identifies optimised investment policies according to the decision maker’s priorities which is evidenced in a case study that shows outperformance against existing maintenance policies for these assets. Financial savings in the region of £8.5M, or the prevention of 1,320 asset failures, were shown to be possible over a 25 years planning horizon in the case study. For the avoidance of confusion, the term ‘integrated’ is considered from the perspective of the three decision making levels associated with the management of an asset, namely: strategic, tactical and operational decision making. Therefore, data quality improvements and the management of information transactions between decisional levels are inherently considered within all of the methodologies developed in this thesis.

The study is not related to any particular development proposal but is rather a guide to future development and the identification of potential environmental hazards. Moreover, it could serve as a set of guidelines for land use planning and management at the urban scale anywhere in South Africa. The evaluation methods used are adapted from widely acceptable analysis techniques and include a combination of both the matrix and the overlay or "sieve" method which graphically analyses physical attributes. The study eminates from the Port Alfred Municipality's concern that demand for development could destroy the town's environmental quality and historical character which are seen as major tourist attractions. The report is divided into two sections, the first being to acquaint the reader with the area, it's constraints and potential. section 1 critically evaluates the existing physical, socio-economic and cultural environments of the town. The second part of the report (Section 2), combines the analysis of the physical and socio-economic environments into an Urban structure Plan and management proposals which provide a basis for the spatial management and control of future land use development proposals. The management proposals are based on the Integrated Environmental Management procedure advocated by the council for the Environment which is adapted to suit local conditions and includes the use of a three stage "proposal call" system which is seen to ensure an equitable balance between the demand for development, public participation and conservation of the town's biotic and abiotic environments. The "proposal call" system has been successfully employed in the United states of America for some years and was adopted by the cape Town city council in 1985 for disposing of council-owned land in a manner most acceptable to itself and the community. By combining both the principle of Integrated Environmental Management and the "proposal call" system Port Alfred should be assured of a future planning strategy which will both enhance development and promote environmental conservation thereby assuring the maintenance of environmental quality.

Full textAbstract:
Current models that assess infrastructure failure risk are â linear,â and therefore, only consider the direct influence attributed to each factor that defines risk. These models do not consider the undeniable relationships that exist among these parameters. In reality, factors that define risk are interdependent and influence each other in a â non-linearâ fashion through feedback effects. Current infrastructure failure risk assessment models are also static, and do not allow infrastructure managers and decision makers to evaluate the impacts over time, especially the long-term impact of risk mitigation actions. Factors that define infrastructure failure risk are in constant change.
In a strategic manner, this research proposes a new risk-based infrastructure management framework and supporting system, Risk-Based Dynamic Infrastructure Management System (RiskDIMS), which moves from linear to non-linear risk assessment by applying systems engineering methods and analogs developed to address non-linear complex problems. The approach suggests dynamically integrating principal factors that define infrastructure failure risk using a unique platform that leverages Geospatial Information System services and extensions in an unprecedented manner. RiskDIMS is expected to produce results that are often counterintuitive and unexpected, but aligned to our complex reality, suggesting that the combination of geospatial and temporal analyses is required for sustainable risk-based decision making. To better illustrate the value added of temporal analysis in risk assessment, this study also develops and implements a non-linear dynamic model to simulate the behavior over time of infrastructure failure risk associated with an existing network of levees in New Orleans due to diverse infrastructure management investments. Although, the framework and RiskDIMS are discussed here in the context of levees, the concept applies to other critical infrastructure assets and systems. This research aims to become the foundation for future risk analysis system implementation.Master of Science

De nos jours, de plus en plus d'organisations déploient des infrastructures matérielles telles que des clusters ou des grilles. Elles sont utilisées pour héberger des services internet communs tels que l'email, les réseaux sociaux ou le commerce électronique ou pour exécuter des applications scientifiques telles que les simulations nucléaires ou les prédictions météorologiques. La capacité de traitement et de stockage demandée pour répondre à la charge de travail de ces applications ne peut être fournie que par le biais de ces infrastructures matérielles. Ces infrastructures matérielles embarquent des systèmes d'exploitation, qui peuvent potentiellement coopérer dans le but de gérer au mieux les ressources disponibles. Ces systèmes gèrent alors l'allocation des ressources aux applications en fonction des besoins de ces dernières. Ces systèmes visent à garantir la qualité de service et en même temps à gérer de façon optimale les ressources dans le but de limiter les coûts, notamment l'énergie. La communauté scientifique s'est intéressée à la problématique de la gestion des ressources. De nombreuses approches ont été proposées et des solutions ont été mises en œuvre. En réalisant un état de l'art de ces approches, nous constatons que la plupart d'entre elles s'intéressent à la gestion des nœuds dans l'objectif de répartir les calculs d'une façon adéquate pour exploiter de manière optimale la charge processeur. La gestion globale de la mémoire dans de telles infrastructures n'a pas été suffisamment étudiée. En effet, la mémoire est souvent considérée comme une ressource avec une capacité théoriquement illimitée grâce aux mécanismes de swap, mais ces derniers ont des conséquences importantes sur les performances des applications et le coût de fonctionnement de l'infrastructure. Dans cette thèse, nous étudions la conception et l'implantation d'un service de gestion globale de la mémoire dans une infrastructure matérielle. Ce service de gestion de mémoire doit éviter le gaspillage de mémoire et ne doit pas pénaliser les performances des applications hébergées. Nous proposons un service de swap à distance permettant à une machine, plutôt que swapper sur son disque local, de swapper sur la mémoire distante d'une autre machine ayant de la mémoire disponible. Les pages distantes peuvent être déplacées dynamiquement afin d'équilibrer la charge entre les machines. Ceci permet de mutualiser la mémoire et d'économiser les ressources. Un prototype a été implémenté et évalué.

Information technology (IT) can be a key contributor for the successful implementation of business strategies. However, companies normally find it hard to synchronize their evolving business strategies with the capabilities in IT. This thesis analyzes the key contributors to the problems in synchronizing business strategy and Information Technology and suggests both management and technical frameworks for an agile IT infrastructure that can stay in sync with the evolving business strategy. Agility in IT infrastructure means the ability for the infrastructure to accommodate evolving needs and business strategies without significant re-architecture. There is no magic bullet that could induce agility into an IT infrastructure and its management. But, this thesis studies the best practices in management and technology which are being used by industry leaders successfully.

Full textAbstract:
Public Private Partnership (PPP) procurement has developed in many countries, as an
effective way for governments to allay their financial burden and/or improve the
efficiencies of public services. However, PPP has also experienced many ups and
downs in its applications. As a collaborative venture between public and private
sectors, the quality of the relationship between them has been shown to be a key
contributor to the success of a PPP project. However, no study has, as yet,
conceptualized and tested an integrative framework for modeling and addressing the
relational aspect in PPP projects. This study aims to fill this gap. Moreover, the
revamping of PPP in the above direction, would align with what is found to be a much
larger trend, in moving from traditional management to relationship approaches in
project management in general and on built infrastructure projects in particular. The
general purpose of this study is to make an original contribution to relationship
research in PPP, by addressing the importance of this intangible side of PPP, through
developing a strategic relationship management framework for parties engaged in PPP
projects.
Having examined relational research in joint ventures, alliancing and
inter-organisational collaboration, it is found that game theory, transaction cost
analysis and relational contracting have a direct bearing on inter-organisational
relationships in infrastructure projects. Consequently, they are adopted as the
theoretical foundations for this research. This study first investigates the ‘hard side’ of
PPP relationships, analyzing their variables based on semi-structured interviews with
PPP experts. Further, the ‘soft side’ of PPP relationships, is found to be influenced
mainly by inter-organisational trust and commitment. This is also investigated in this
research by intensive literature review of inter-organisational relationships. A
relational variables and indicators model for PPP projects is then developed.
Quantitative research data was collected from two questionnaire surveys, targeting
international experiences. The first survey was aimed to examine the intensifying
and/or moderating effects of various relational variables. The second survey was
designed to identify the Critical Success Factors of relationship management in PPP
context. Qualitative research data was consolidated from a case study and follow-up
structured interviews. Findings from surveys, case study and interviews were then
triangulated to develop a strategic framework for better relationship management for
infrastructure PPP projects.
The findings from this research make a specific contribution to relationship
management research; while the ‘hard’ and ‘soft’ sides provide lenses for both PPP
parties to examine their relationship with their respective partners. The proposed
strategic framework consists of a Relationship Management Scheme and Guidelines
to be implemented in different PPP phases, through addressing the sustainability of
the relationship. It provides an initial scheme or base approach for project parties to
manage the relationships proactively rather than reactively. Besides, this research also
helps to identify relevant relational components that can be incorporated or directly
used in criteria for pre-tender selection. Such screening and special attention to these
critical components can also help to develop more sustainable relationships and attain
better value for money through PPP procurement in practice.published_or_final_version

Full textAbstract:
Infrastructure is presenting significant national and global challenges. Whilst often seen as performing well, infrastructure tends to do so against only limited terms of reference and short-term objectives. Given that the world is facing a new infrastructure bill of ~£40T, improving the benefits delivered by existing infrastructure is vital (Dobbs et al., 2013). This thesis investigates strategic intent and the management of infrastructure systems; how factors such as organisational structure and business practice affect outcomes and the ways in which those systems — not projects — are managed. To date, performance has largely been approached from the perspective of project investment and/or delivery, or the assessment of latent failures arising from specific shocks or disruptive events (e.g. natural disaster, infrastructure failures, climate change). By contrast, the delivery of system-level services and outcomes across the infrastructure system has been rarely examined. This is where infrastructure forms an enduring system of services, assets, projects, and networks each at different stages of their lifecycle, and affecting one another as they develop, then age. Yet system performance, which also includes societal, organisational, administrative and technical factors, is arguably the level relevant to, and the reality of, day-to-day public infrastructure management. This research firstly investigated industry perceptions in order to test and confirm the problem: the nub of which was the inability to fully deliver appropriate and relevant infrastructure outcomes over the long term. Three detailed studies then explored the reasons for this problem through different lenses; thereby providing an evidence-base for a range of issues that are shared by the wider infrastructure industry. In confirming its hypothesis that “the strategic intent and the day-to-day management of infrastructure systems are often misaligned, with negative consequences for achieving the desired long-term infrastructure system outcomes”, this research has increased our understanding of the ways in which that misalignment occurs, and the consequences that result. It found those consequences were material, and frequently not visible within the sub-system accountable for the delivery of those outcomes. That public infrastructure exists, not in its own right, but to be of benefit to society, is a central theme drawn from the definition of infrastructure itself. This research shows that it is not enough to be focused on technical outcomes. Infrastructure needs to move beyond how society interacts with an asset, to the outcomes that reflect the needs, beliefs, and choices of society as well as its ability to respond to change (aptitude). Although the research has confirmed its hypothesis and three supporting propositions, the research does not purport to offer ‘the solution’. Single solutions do not exist to address the challenges facing a complex adaptive system such as infrastructure. But the research does offer several system-oriented sense-making models at both the detailed and system-level. This includes the probing methodology by way of a diagnostic roadmap. These models aim to assist practitioners in managing the transition of projects, assets, and services into a wider infrastructure system, their potential, and in (re)orienting the organisation to the dynamic nature of the system and its societal imperative.

Full textAbstract:
Physical infrastructure assets are important components of our society and our
economy. They are usually designed to last for many years, are expected to be
heavily used during their lifetime, carry considerable load, and are exposed to the
natural environment. They are also normally major structures, and therefore present
a heavy investment, requiring constant management over their life cycle to ensure
that they perform as required by their owners and users.
Given a complex and varied infrastructure life cycle, constraints on available
resources, and continuing requirements for effectiveness and efficiency, good
management of infrastructure is important. While there is often no one best
management approach, the choice of options is improved by better identification and
analysis of the issues, by the ability to prioritise objectives, and by a scientific
approach to the analysis process. The abilities to better understand the effect of
inputs in the infrastructure life cycle on results, to minimise uncertainty, and to
better evaluate the effect of decisions in a complex environment, are important in
allocating scarce resources and making sound decisions.
Through the development of an infrastructure management modelling and analysis
methodology, this thesis provides a process that assists the infrastructure manager in
the analysis, prioritisation and decision making process. This is achieved through
the use of practical, relatively simple tools, integrated in a modular flexible
framework that aims to provide an understanding of the interactions and issues in the
infrastructure management process.
The methodology uses a combination of flowcharting and analysis techniques. It
first charts the infrastructure management process and its underlying infrastructure
life cycle through the time interaction diagram, a graphical flowcharting
methodology that is an extension of methodologies for modelling data flows in
information systems. This process divides the infrastructure management process
over time into self contained modules that are based on a particular set of activities,
the information flows between which are defined by the interfaces and relationships
between them.
The modular approach also permits more detailed analysis, or aggregation, as the
case may be. It also forms the basis of ext~nding the infrastructure modelling and
analysis process to infrastructure networks, through using individual infrastructure
assets and their related projects as the basis of the network analysis process.
It is recognised that the infrastructure manager is required to meet, and balance, a
number of different objectives, and therefore a number of high level outcome goals
for the infrastructure management process have been developed, based on common
purpose or measurement scales. These goals form the basis of classifYing the larger
set of multiple objectives for analysis purposes. A two stage approach that
rationalises then weights objectives, using a paired comparison process, ensures that
the objectives required to be met are both kept to the minimum number required and
are fairly weighted. Qualitative variables are incorporated into the weighting and
scoring process, utility functions being proposed where there is risk, or a trade-off
situation applies.
Variability is considered important in the infrastructure life cycle, the approach used
being based on analytical principles but incorporating randomness in variables where
required. The modular design of the process permits alternative processes to be used
within particular modules, if this is considered a more appropriate way of analysis,
provided boundary conditions and requirements for linkages to other modules, are
met.
Development and use of the methodology has highlighted a number of infrastructure
life cycle issues, including data and information aspects, and consequences of
change over the life cycle, as well as variability and the other matters discussed
above. It has also highlighted the requirement to use judgment where required, and
for organisations that own and manage infrastructure to retain intellectual knowledge
regarding that infrastructure.
It is considered that the methodology discussed in this thesis, which to the author's
knowledge has not been developed elsewhere, may be used for the analysis of
alternatives, planning, prioritisation of a number of projects, and identification of the
principal issues in the infrastructure life cycle.

Full textAbstract:
One of the vital processes for the maintenance of infrastructure is the collection of information about the inventory and current state of the infrastructure. Such activities are mostly done manually by the inspector in the field. However, Unmanned Aerial Vehicles (UAV) offer the possibilities to improving the accuracy, precision, and efficiency of those tasks. The present dissertation focusses on the evaluation of the requirements and possibilities for the incorporation of UAV in the assessment of port infrastructure, with an emphasis on pavement infrastructure. The first step to reach the goal of the research was the elaboration of an extensive literature review where the leading practices and trends for the use of Unmanned Aerial Systems (UAS) were identified. Based on the literature review, it was possible to propose a roadmap for the implementation of the UAS in the assessment of port infrastructure. The roadmap was implemented in a case study for the Norvik port in Stockholm while the restrictions and information allowed. This research produced several key findings. First, it was possible to recognize the lack of precise definitions in the pavement assessment, the faults in the current manual collection of pavement distresses and the voids in an investigation regarding the recognition of pavement defects different than cracking as some of the critical problems in the area. Additionally, the current applications like bridge and structural inspection, and available technologies like LiDAR or visual sensors were identified along with its improvement opportunities and restrictions. The key steps for the implementation of a UAS for assessing infrastructure were formulated as the identification of the needs and critical parameters, the selection of the UAS components, mainly the UAV and sensor, and the postprocessing of the data. The main conclusion drawn from the research is that it is possible to use UAS to assess the state of the infrastructure. However, not all UAS are suitable for all situations or necessities. The selection of the UA, according to the needs and limitations of the project, plays a vital role regarding the viability of implementation of a UAS for monitoring port infrastructure. The sufficiency of a UAS is closely related on its capability to acquire the information of the selected structures, with the required quality, and overcome the limitations, challenges, and restrictions of the site of application. As a way forward, the most important element to address is the implementation of Machine Learning (ML) techniques and Artificial Intelligence (AI) to extract the relevant features of the data automatically.

The global financial crisis, which was unique in its magnitude and after effects, has generated significant interest in Public Private Partnership (PPP). Lack of investments and deteriorated infrastructure challenges economic competitiveness of countries in global market and forced governments to look innovative ways to fund the projects. PPP is a successful model in many developed economies. Availability of funding, efficiency, timely completion and regular maintenance in PPPs are main attraction for governments. While misallocated and mismanaged federal funds, inefficiency and trust deficit are key concerns when government build & finance infrastructure projects. This study explores pros and cons of PPP in challenging economic environment, evaluate key success factors and provide review of few case studies.

Full textAbstract:
This research studies procuring complex performance (PCP) in the case of public infrastructure projects. Focus of the research is on the interface between public clients and private sector contractors. Purpose of this research is to find out what are the main challenges of different project delivery methods according to literature (RQ1) and what are the practical challenges of public procurement (RQ2). As an end result, research provides recommendations on how to improve public procurement in a way which benefits the whole industry based on both literature and data collected. The results from this research are applicable to the local infrastructure sector in Oulu, where the research was conducted, and with limitations to other regions and public organizations in Finland. The research method used for this research was an embedded multiple-case study with multiple units of analysis. Two public organizations located in Oulu area that are procuring infrastructure projects were chosen as case organizations. The observation of the field was done by interviewing members of local organizations involved in infrastructure construction. In order to draw conclusions about public procurement, both public and private sector representatives were interviewed. In addition to interviews, a thorough literature review was conducted in order to compare results from interviews to the current literature. Public organizations in Finland have constantly been downsized by the government and this trend seems to continue in the future. This means more and more work is done by the private sector consultants and contractors. Contractors, however, prefer a strong client organization and therefore public clients perhaps should try to procure and supervise projects themselves instead of using consultants, thus also maintaining their procurement expertise and skills. Improving public procurement would also require changes in the current political process. The next year’s investment plans and budgets should be decided and revealed earlier in order to provide adequate time for designing and tendering. Public clients should also start making the most out of the possibilities the legislation allows and increasingly use innovative project delivery methods in their procurement. This would enable innovation activity needed to develop the whole industry. Currently a majority of the projects are delivered using traditional project delivery methods like design-bid-build (DBB)Tämä tutkimus tarkastelee monimutkaisten tuotteiden ja palveluiden hankintaa julkisten infrahankkeiden tapauksessa. Tutkimus keskittyy erityisesti julkisten tilaajien ja yksityisten urakoitsijoiden väliseen rajapintaan. Tarkoituksena on saada selville mitä haasteita eri projektin toteutusmuotoihin liittyy kirjallisuuden perusteella (RQ1) ja mitä käytännön haasteita julkiseen hankintatoimeen liittyy (RQ2). Lopputulemana tutkimus esittää parannusehdotuksia julkiseen hankintatoimeen perustuen sekä kirjallisuuteen että empiiriseen tutkimukseen. Esitetyt parannusehdotukset ovat käyttökelpoisia paikallisen infrasektorin lisäksi myös tietyin rajoituksin muualla Suomessa toimiviin julkisiin organisaatioihin. Tutkimusmenetelmänä työssä käytettiin monitapaustutkimusta. Kaksi Oulussa sijaitsevaa julkista organisaatiota, jotka hankkivat infrahankkeita, valittiin case organisaatioiksi. Tiedonkeruu tutkimusta varten tapahtui haastattelemalla paikallisten, infrasektoriin kuuluvien, organisaatioiden jäseniä. Johtopäätösten tekemiseksi haastateltaviin kuului sekä julkisten että yksityisten organisaatioiden edustajia. Haastatteluiden lisäksi perusteellinen kirjallisuuskatsaus tehtiin, jotta haastatteluiden tuloksia kyettiin vertaamaan nykykirjallisuuteen. Julkisia organisaatioita on Suomessa jatkuvasti pienennetty ja sama kehitys näyttää jatkuvan myös tulevaisuudessa. Tämä tarkoittaa töiden siirtymistä yhä enemmän konsulttien ja urakoitsijoiden harteille. Urakoitsijat kuitenkin suosivat vahvaa tilaajaorganisaatiota ja siitä syystä julkisten tilaajien tulisi ehkä pyrkiä säilyttämään vahva tilaajaorganisaatio hankkimalla ja valvomalla hankkeita itse konsulttien sijaan näin myös säilyttäen oman hankintaosaamisensa. Julkisen hankinnan kehittäminen vaatisi muutoksia myös nykyiseen poliittiseen prosessiin. Seuraavan vuoden investointisuunnitelmista ja budjeteista tulisi tehdä päätöksiä aiemmin, jotta riittävästi aikaa jäisi hankkeiden suunnitteluttamiseen ja kilpailuttamiseen. Julkisien tilaajien tulisi myös alkaa hyödyntämään paremmin hankintalainsäädännön suomia mahdollisuuksia käyttämällä yhtä enemmän innovatiivisia projektien toteutusmuotoja. Tämä mahdollistaisi innovaatiotoimintaa, joka on edellytys koko alan kehitykselle. Nykyään suurin osa projekteista toteutetaan käyttäen perinteisiä projektin toteutusmuotoja kuten kokonaishintaurakkaa

Full textAbstract:
Considering 91 countries with seaports, this study conducted an empirical inquiry into the broader economic contribution of seaborne trade, from a port infrastructure quality and logistics performance perspective. Investment in quality improvement of port infrastructure and its contribution to economy are often questioned by politicians, investors and general public. A structural equation model (SEM) is used to provide empirical evidence of significant economic impacts of port infrastructure quality and logistics performance. Furthermore, analysis of a multi-group SEM is performed by dividing countries into developed and developing economy groups. The results reveal that it is vital for developing countries to continuously improve the quality of port infrastructure as it contributes to better logistics performance, leading to higher seaborne trade, yielding higher economic growth. However, this association weakens as the developing countries become richer.

Thesis (MBA)--Stellenbosch University, 2001.ENGLISH ABSTRACT: Strategic management and planning is essential to local government. It provides the framework against which the quality of life of the community and economic development are supported by local government. The strategic plan is the framework used to determine whether local government supports the National Government's objectives in respect of the Reconstruction and Development Program and complies with the requirements of the legislation in respect of local government. The purpose of the research is a critical evaluation of the Port Elizabeth Municipality (PEM) strategic planning process. The aim is firstly to determine whether the PEM Strategic Plan is in compliance with the requirements of the Integrated Development Plan as prescribed by legislation, and secondly to determine whether both the PEM strategic planning process and the integrated development planning process are in compliance with the academic literature requirements of the conventional strategic planning process. The evaluation results in the formulation of conclusions and recommendations in respect of deficiencies that affect the success or failure of the PEM Strategic Plan. The research demonstrates that the determination of meaningful strategies in order to satisfy a specific objective is critical for the successful implementation of the PEM Strategic Plan. The deficiencies that were identified during the implementation phase of the PEM Strategic Plan, confirm the necessity of having in place an appropriate organisational structure and culture that supports the strategies. The research also indicates the necessity of having frequent and thorough communication of implementation results, human resource management and the buy-in and acceptance of the strategic process by motivated staff in order to promote the achievement of the vision and the mission statement of PEM.

Dit verskaf die raamwerk waarvolgens die lewensgehalte van die gemeenskap verhoog en ekonomiese ontwikkeling deur die plaaslike owerheidsektor bevorder word. Die strategiese plan dien as die metingsraamwerk waarvolgens bepaal word of plaaslike owerhede die doelwitte van die nasionale regering se Heropbou en Ontwikkelingsprogram ondersteun en aan die vereistes van die wetgewing, wat daarop van toepassing is, voldoen. Die doel van die navorsing is 'n kritiese evaluasie van die Port Elizabeth Munisipaliteit (PEM) strategiese beplanningsproses. Eerstens word bepaal of die PEM Strategiese Plan voldoen aan die vereistes van die Geintegreerde Ontwikkelingsplan soos wat deur die " wetgewing voorgeskryf word, en tweedens of beide die PEM strategiese beplanningsproses en die geintegreerde ontwikkelingsbeplanningsprosesse voldoen aan die akademiese vereistes verbonde aan die konvensionele strategiese beplanningsproses. Die evaluasie lei tot die maak van gevolgtrekkings en aanbevelings ten opsigte van die leemtes en probleme wat die sukses of mislukking van die PEM Strategiese Plan beinvloed. Die navorsing toon dat die bepaling van verstaanbare strategiee, ten einde 'n spesifieke doelwit te bereik, van uiterste belang is vir die suksesvolle implementering van die PEM Strategiese Plan. Die probleme wat tydens die implementering van die PEM Strategiese Plan gei'dentifiseer is, bevestig die noodsaaklikheid van die daarstelling van 'n toepaslike organisasiestruktuur en -kultuur wat die geformuleerde strategiee behoorlik kan ondersteun. Die navorsing dui ook aan die noodsaaklikheid van gereelde en behoorlike kommunikasie van implementeringsresultate, menslike hulpbronbestuur en die inkoop van gemotiveerde personeel tot die strategiese proses ten einde die suksesvolle bereiking van die visie en die missiestelling van PEM te bevorder.

Thesis (MBA)--Stellenbosch University, 2014.Namibian ports are state-owned and have fallen behind in terms of port reform The ports are increasingly pressurised by port users and even more so by shipping lines for infrastructure investment and technological advancement without any guarantee of return on investments. Increased competition amongst ports as well as a shift in the balance of power to port users, demands of Namibia to review its port governance and ownership structure to ensure that the country remains responsive to the changing global marketplace contribute to these pressures. This study deals with the complexities associated with port reform and port competition. The paper presents a synthesis of literature on port governance models and port reform. In addition, this paper also presents an analysis of the port choice decisions made by port users and reviewed port reform case studies of two African ports. Drawing from the lessons in case studies, it is clear that various options of port reform have emerged over the years, each with its own strengths and weaknesses. The study further shows similarities in the objectives of port users when choosing a port but applying different strategies to achieve their objectives.

The incidence and consequences of adolescent substance abuse for the health and well-being of adolescents, their significant others and society at large, have become an increasing concern. The early onset of substance use further enhances the potential for addiction, thus emphasizing the need for early identification and intervention. The literature and practice observations suggest that parental management, which includes parenting practices such as parental monitoring, clear rules about substance use and the modelling of protective, constructive behaviours, protects adolescents from the onset of substance use and interrupts the adolescent’s progression to substance abuse. This qualitative study aimed to explore and describe parental management of adolescent substance abuse in the Nelson Mandela Metropole. An exploratory- descriptive and contextual research design was employed in this study. Furthermore, non-probability purposive sampling, in conjunction with snowball sampling techniques, was employed to recruit parents who have or continue to manage their adolescents (between the ages of 13-18 years) substance abuse and the associated impact that it has of on the family in the past year. Semi-structured individual interviews were conducted with ten parents, and data collection ceased upon reaching data saturation. The generated data was analysed using thematic data analysis. The trustworthiness of the research process and the findings was enriched by engaging in a variety of data verification strategies. The following main themes emerged from the data analysis process: Participants’ perspective of adolescent substance use in their community; Participants’ experiences of their own child’s substance use; Impact of substance use on the family system; Participants’ perspective of their role in managing adolescent substance use; and, Participants’ support needs in relation to adolescent substance use. The findings contribute to a greater understanding of what parents require to effectively prevent and/or manage substance abuse by their adolescent children. The findings furthermore recommend preventive interventions at both primary and secondary level.

Full textAbstract:
Due to scarce financial resources, over-stretched budgets, pressures for service delivery and the dynamic nature of local government, asset management plays a key strategic role in enhancing local municipal functionality and efficiency. Asset management is the management of physical assets, infrastructure, and immoveable assets. It is an evolving discipline that is enhanced by the understanding of asset conditions and performance. It improves decision-making within local government. Every year, local government announces millions of Rands’ worth of assets that are unaccounted for and that go missing in annual reports. It was the purpose of this study to assess the asset management function at the Nelson Mandela Bay Municipality (NMBM). The aim is to improve the management of moveable assets by investigating the following variables: strategic management of assets, knowledge management, governance, leadership, the impact of corruption and skills management. The approach to the study is a qualitative research paradigm with a case study methodology and an interview as a research instrument. The sample chosen comprised people from the top level of municipal management down to municipal asset controllers. The two forms of data that were collected in the study were primary data and secondary data. Primary data was collected from municipal workers and collated together for analysis purposes. Secondary data was gathered from library sources such as journals, books, conference papers, government acts, municipal policies and local newspapers. This data informed the interview questions. The interview strategy was chosen as the best way to conduct the empirical part of this research and was guided by an interview guide. The study found that there are operational defects in the way asset management is organised. This makes the function seem unimportant. The results also indicated a lack of staff members and skills shortages; such as management and computer skills. Indications are that theft, negligence, corruption and carelessness negatively impact the management of assets. Recommendations include the filling of vacant posts, tightening of internal controls, providing the necessary training and improving the asset management. The study makes a contribution to the current body of knowledge.

Interoperability between Geographic Information System (GIS) of different
infrastructure companies is still a problem to be handled. Infrastructure companies
deal with many operations as a part of their daily routine such as a regular
maintenance, or sometimes they deal with unexpected situations such as a
malfunction due to natural event, like a flood or an earthquake. These situations
may affect all companies and affected infrastructure companies response to these
effects. Responses may result in consequences and in order to model these
consequences on GIS, GISs are able to share information, which brings the
interoperability problem into the scene.
The present research, aims at finding an answer to interoperability problem between
GISs of different companies by considering contextual information. During the
study, the geographical features are handled as the major concern and
interoperability problem is examined by targeting them. The model constructed in
this research is based on the ontology and because the meaning of the terms in the

Wireless infrastructure networks provide high-speed wireless connectivity over a small geographical area. The rapid proliferation of such networks makes their management not only more important but also more difficult. Denser network deployments lead to increased wireless contention and greater opportunities for RF interference, thereby decreasing performance. In the past, wireless site surveys and simplified wireless propagation models have been used to design and configure wireless systems. However, these techniques have been largely unsuccessful due to the dynamic nature of the wireless medium. More recently, there has been work on dynamically configurable systems that can adapt to changes in the surrounding environment. These systems improve on previous approaches but are still not adequate as their solutions make unrealistic assumptions about the operating environment. Nevertheless, even with these simplified models, the network design and configuration problems are inherently complex and require tradeoffs among competing requirements.
In this thesis, we study a self-management system that can adjust system parameters dynamically. We present a system that does not impose any restrictions on the operating environment, is incrementally deployable, and also backwards compatible. In doing so, we propose, (i) framework for modeling system performance based on utility functions, (ii) novel approach to measuring the utility of a given set of configuration parameters, and (iii) optimization techniques for generating and refining system configurations to maximize utility. Although our utility-function framework is able to capture a variety of optimization metrics, in this study, we focus specifically on maximizing network throughput and minimizing inter-cell interference. Moreover, although many different techniques can be used for optimizing system performance, we focus only on transmit-power control and channel assignment. We evaluate our proposed architecture in simulation and show that our solution is not only feasible, but also provides significant improvements over existing approaches.

Full textAbstract:
Infrastructure organizations use diversified information systems to exchange data (transaction). Presently, data exchange in the area of infrastructure management is accomplished in a manual and ad hoc basis. The growing trend is to transform these manual data exchanges to a computer-to-computer based transactions. The core research questions include:
What transactions are candidates to formalize?—this question is dealt with identifying and selecting a potential transaction for IT improvement—Asset Inventory and Condition Assessment Reporting/Tangible Capital Asset (AI&CAR/TCA) Reporting.
Why formalize transactions?”—this question is dealt with developing and applying an Infrastructure Management—Process Maturity Model to assess the degree to which work processes and communications are formalized in infrastructure management. The results indicate that the work processes and communications are currently performed on an ad hoc basis.
How to formalize and manage transactions?— this question is dealt with developing and applying an ontology-supported Transaction Formalism Protocol (TFP), which is composed of two parts: ontology and protocol. Two ontologies, the Transaction Domain Ontology and Tangible Capital Asset ontology, were developed to represent transaction domain knowledge and Tangible Capital Asset knowledge respectively to support the design, management, and implementation of transactions in infrastructure management. Moreover, an eight-step procedure—the TFP was developed from two perspectives: The TFP Specification modeled each step of the protocol as a function for which inputs, controls, mechanisms, tools/techniques, and outputs were defined, whereas the TFP Tool includes a set of forms and guidance developed for specific steps of the protocol.
The proposed TFP was applied to develop transaction specification for the AI&CAR/TCA Reporting, which was managed and implemented through developing the Infrastructure Transaction Management Portal and Asset Information Integrator System repectively.
The evaluation results indicate that both the ontologies are consistent, concise, complete, correct, and clear. Similarly, the protocol was found to be feasible, usable, useful, and generic. The major contributions include the development of two ontologies and protocol, whereas the medium contributions are: IT use survey, development of the IM-PMM, portal, and asset integrator information system. The minor contribution; however, includes the development of the transaction specification for the AI&CAR/TCA Reporting.Applied Science, Faculty of
