The military community has considerable experience in the areas of procuring and managing large systems. These systems are often expected to perform their intended function over a period of several years and as a result, they will require an extensive support structure consisting of personnel, equipment and spare assets. For this reason, Logistics Management has always been an important field within the military and is gaining recognition within private industry as well. The evolutionary process which starts with the identification of a need and continues through design, production and retirement is known as a product's life cycle. Studies have shown that the decisions which are made initially, during the design of the product, will determine 80% of the total system costs. Several efforts have been initiated to improve the product design process and emphasize the life cycle approach. These include; Concurrent Engineering, Logistics Support Analysis (LSA) and Quality Function Deployment (QFD). These efforts necessitate an overhaul of the decision-making methods used in the product design process. Consequently, within the military community and private industry, the time-honored sequential-hierarchical-decision approach to design is being replaced with concurrent decision-making. The sequential process of the hierarchical method can lead to suboptimal designs which significantly increase manufacturing and follow-on support costs. / Ph. D.

Wind power is one of the fastest growing energy sources, which have advantages in terms of delivering clean, cheap and fast energy. Many actors and organizations have realized this potential, which has lead to exponential growth of the wind power over recent couple of years. Despite promising future of clean and green energy through wind there are still areas to be improved to tackle main hinders for further development on a larger scale. The larger scale development of wind power has up-to-date been reached in only few countries such asDenmarkandGermany. The most potential can be found through offshore wind turbines due to, among other, lesser height and noise restrictions than inland wind turbines as well as better wind resources. This thesis is mainly characterized by the mixed-method method, which is in its turn characterized by mixing different research methods such as induction, deduction and abduction as they might be suitable to apply during the different stages of the research process. In this thesis the system approach will be considered to model the scope of this study’s context. As this thesis was constructed as a theoretical study the systematic literature review was used as the main source for data collection. The synthesis of the reviewed articles was initially performed in a broad manner to show overall picture of research related to the scope of this thesis. In the following step, the adopted LCM tool was used to extract study specific data from the reviewed and additional articles. This enabled to link some of the current problems, in wind power area, and ‘unfulfilled’ stakeholder requirements.    This thesis aim was to identify important stakeholders and to address their respective requirements within the scope of supportability engineering applied in the wind power context, particularly stakeholder requirements that have not been considered by previous research. The purpose of it was to compare different requirements with current issues in the wind power sector. Conducted systematic literature review showed significant and costly (development) issues related to the supportability engineering such as reliability, availability, maintainability, accessibility problems etc. This was fully in line with the stakeholders’ requirements, which in several cases demanded higher dependability i.e. availability performance and its influencing factors.  The thesis also included definition of supportability engineering framework, through comparing several widely accepted and standardized theoretical concepts. This comparison enabled definition of more focused approach with requirements on the ‘supported system’ and to lesser extent the ‘support system’. These requirements are usually mixed within the different theoretical concepts.  The main findings from this study are that application of supportability engineering framework would lead to earlier identification of important stakeholders and their requirements. Considering these requirements, for instance availability and maintainability of the wind turbines, at earlier stages of the life cycle through better design and improved supportability infrastructure could potentially decrease amount of current problems in the wind energy sector in particular for the offshore part. Another result was that different stakeholders and their requirements were identified. Thesis contribution overall was a new ‘refined approach’ to deal with supportability issues through supportability engineering framework, whose main focus is the ‘supported system’.

Syfte:Syftet med studien är att undersöka vilka faktorer som påverkar projektering av en järnvägsanläggning ur ett livscykelperspektiv. Målet är att tydliggöra vad Trafikverket behöver ta hänsyn till vid projektering av en järnvägsanläggning för att kunna uppnå de krav som ställs på järnvägsanläggningen samt öka förutsägbarheten för livscykelkostnaden. Frågeställningar:Hur kan projektering av järnvägsanläggningar förbättras ur ett livscykelperspektiv? Vilka faktorer behöver Trafikverket ta hänsyn till vid projekteringsfasen för att säkerställa tillförlitliga och kostnadseffektiva järnvägsanläggningar? Hur kan en arbetsmetodik formas för att främja en kostnadseffektiv järnvägsanläggning? Metod:Följande studie är baserad på en kvalitativ fallstudie. Metoden är baserad på semistrukturerade intervjuer och dokumentationsmetodik för att erhålla empiriska data. Litteraturstudien och det teoretiska ramverket är baserade på expertgranskade tidskrifter, vetenskapliga artiklar och böcker som täcker studieområdena. Slutsats:Studien har visat att projektering av järnvägsanläggningar ur ett livscykelperspektiv kan förbättras genom att ta fram konkreta underlag för att stödja de besluts som ska tas. Beslutsunderlag för järnvägsanläggningen bör baseras på olika analyser för att kunna värdera vilket alternativ som ger den mest kostnadseffektiva anläggningen samtidigt som det återspeglar de efterfrågade målen och kraven. Analyser ska inte enbart baseras på tekniska konstruktion utan även driften samt underhållet behöver beaktas eftersom de har en stor inverkan på utfallet av kapaciteten, prestandan och kostnader över hela anläggningens livscykel. Vidare har studien visat vikten av att ha tillförlitliga system som kan ge information om anläggningen och även all data som krävs för att utföra analyser. / Purpose:The purpose of the study is to investigate which factors affect life-cycle planning of a railway infrastructure.

Research questions:How can railway infrastructure planning phase be improved based on a life-cycle perspective? What factors do the Swedish Transport Administration need to take into account during the planning phase to ensure reliable and cost-effective railway infrastructure? How can a working methodology be designed to promote a cost-effective railway infrastructure? Method:The following study is based on a qualitative case study. The literature study and the theoretical framework are based on peer-reviewed journals, scientific articles and books that covers the areas of the study. The empirical data collection is based on semi-structured interviews and reports from different administrative authority. Conclusion:This study has shown that planning of railway infrastructure from a life-cycle perspective can be improved by concrete evidence to support the decisions to be taken. The decisions basis for the railway infrastructure should be based on various analysis in order to evaluate the most cost-effective option while reflecting the desired goals and requirements. However, analysis should not only be based on the technical design. It should also consider operation and maintenance, since they have a major impact on the outcome of capacity, performance and cost throughout the life-cycle of railway infrastructure. Furthermore, the study has demonstrated the importance of having reliable systems that can provide information about the railway infrastructure and all data required for carrying out analysis.

A cadeia de suprimentos abrange todas as atividades relacionadas com o fluxo e a transformação de produtos desde a matéria-prima na etapa de extração, até chegar ao consumidor final. Envolve, ainda, os fluxos de informações e transformações para cima e para baixo da cadeia de suprimentos. A pesquisa apresenta como objetivo geral avaliar a gestão da cadeia de suprimentos ambiental em uma indústria alimentícia e, como objetivos específicos: desenvolver e aplicar uma metodologia própria para selecionar artigos de relevância científica na área da cadeia de suprimentos sustentável; desenvolver e aplicar uma metodologia específica para conhecer os métodos de avaliação da gestão da cadeia de suprimentos sustentável em periódicos de alto fator de impacto; e, mediante um estudo de caso, desenvolver uma metodologia de pesquisa estruturada, para que se possa avaliar a gestão da cadeia de suprimentos ambiental em uma indústria do ramo alimentício, localizada no estado de Santa Catarina. Com relação à metodologia de pesquisa, foi realizada uma revisão da literatura de forma estruturada em doze passos principais, além do estudo de caso que ocorreu mediante a aplicação de uma metodologia composta por sete constructos, a saber: estágio da gestão ambiental, seleção de fornecedores, colaboração com fornecedores, avaliação de fornecedores, seleção de cientes, colaboração com os clientes e avaliação de clientes. No que se refere aos resultados da pesquisa, o estudo possibilitou testar e aprimorar a metodologia de pesquisa própria, bem como permitiu apresentar um panorama da situação da empresa estudada, onde foi diagnosticado que, em relação ao constructo denominado estágio da gestão ambiental, a empresa apresentou média satisfatória, isso se deve a questões legais e procedimentos internos praticados pela empresa. No entanto, no que se refere aos constructos ‘seleção de fornecedores, colaboração com os fornecedores, avaliação de fornecedores, seleção de clientes, colaboração com os clientes, avaliação de clientes’, a empresa apresentou média insatisfatória. Percebe-se que a empresa realiza ações ambientais, objetivando não sofrer as sanções cabíveis, mas se preocupando de fato, com a sustentabilidade ambiental da cadeia de suprimentos. / The supply chain covers all activities related to the flow and transformation of products from the raw material in the extraction stage, to the final consumer. It also involves downstream and upstream information and transformation flows in the supply chain. The objective of this study is to evaluate the management of the environmental supply chain in the food industry and, as specific objectives: to develop and apply a specific methodology to select articles of scientific relevance in the field of sustainable supply chain; to develop and apply a specific methodology to know the methods of evaluation of sustainable supply chain management in high impact factor journals; and, through a case study, to develop a structured research methodology to evaluate the management of environmental supply chain in the food industry located in the state of Santa Catarina. With regard to the research methodology, a literature review was carried out in a structured form in twelve main steps, in addition to the case study, which occurred through the application of a methodology composed of seven constructs, namely: environmental management stage, supplier selection, supplier collaboration, supplier assessment, customer selection, customer collaboration, and customer assessment. With regard to the research results, the study made it possible to test and improve a specific research methodology, as well as to present an overview of the situation of the company studied, where it was diagnosed that, in relation to the construct denominated environmental management stage, the company presented a satisfactory average, which is due to legal issues and internal procedures it possesses. However, with respect to the constructs selection of suppliers, collaboration with suppliers, supplier evaluation, client selection, collaboration with customers, and customer evaluation, the company presented an unsatisfactory average. One may notice that the company performs environmental actions, aiming not to suffer the applicable sanctions, but actually due to a true concern with the environmental sustainability of the supply chain.
