En intégrant le cycle de vie d'un bien dans son processus de développement, l'éco-conception permet d'améliorer la performance environnementale de ce futur produit. La combinaison, dans cette thèse, des notions de la conception centrée utilisateur et de la pensée cycle de vie, permet de proposer une méthode pour l'intégration de la phase d'utilisation en éco-conception. La méthode repose sur la proposition de nouveaux modèles pour représenter l'utilisation adaptés aux spécificités de l'éco-conception. A partir du modèle de produit, un modèle de la phase d'utilisation, connectée aux phases de distribution et de fin de vie, permet d'associer l'utilisation du produit à son cycle de vie complet. Le modèle de contexte permet de positionner la performance environnementale du produit en utilisation par rapport à des paramètres associés à l'utilisateur et à l'environnement d'utilisation. L'évaluation environnementale du scénario d'utilisation regroupant tous ces modèles permet d'adapter les stratégies d'amélioration de la méthode à l'utilisation d'un produit en conception. Une application de la démarche à la re-conception d'un réfrigérateur pour la France et le Brésil permet d'illustrer le fonctionnement de la méthode. / By integrating product life cycle into the developement process, ecodesign enables the environnemental improvement of the product to be. The combination of user centred design proposition and life cycle thinking allows us to propose a method for use phase integration in ecodesign. This method is built on new models to represent product use that are compatible with ecodesign specificity. Based on the product model, the use phase model, which is connected to the distribution and end-of-life phases, facilitates the attachment of product use to the complete life cycle. Context model aims at possitionning the product use environmental performance according to influencing parameters related to the user and it environment. Environmental assessment is made based on the use scenario, a combination of the three previous models. This assessment enables to adapt the improvements strategies to the specificity of a product use phase. A case study has been perform to illustrate the capability of the new proposal to ecodesign a refrigerator for Brazil and for France.

A Gestão do Ciclo de Vida (LCM) pode ser entendida como uma abordagem para melhorar continuamente o desempenho em sustentabilidade da organização e de seus produtos e serviços por meio da incorporação do pensamento de ciclo de vida nas práticas de negócio. Entretanto, faltam instrumentos de gestão para auxiliar na sua operacionalização e implementação. Nesse sentido cabe destacar as possibilidades advindas da abordagem de Gestão por Processos de Negócio (BPM), que visa a reestruturação e otimização das atividades organizacionais. Este trabalho teve como objetivo identificar e analisar as relações entre essa duas abordagens, verificando as possibilidades de contribuições entre elas. Para isso foi conduzida uma revisão bibliográfica sistemática para identificar as definições e práticas de BPM e LCM, que foram utilizadas para a elaboração de definições de trabalho e para a análise das relações entre as práticas e os processos de negócio. Adicionalmente, foi realizado um estudo bibliométrico para identificar relações entre as duas áreas de pesquisa, a partir do qual é possível afirmar que não há referencial teórico compartilhado entre as duas áreas. Em contrapartida, os resultados da análise de publicações indicam que as práticas de BPM estão relacionadas com os processos de negócio e com o desempenho da organização, e que muitas práticas de LCM estão sendo aplicadas nos processos de negócio, havendo assim uma relação indireta entre as abordagens. Além disso, foram identificadas oportunidades de contribuição relacionados a teoria e prática dessas abordagens: BPM possui um conjunto de práticas para a gestão e melhoria dos processos com base no planejamento estratégico, enquanto LCM possui elementos e práticas que visam a sustentabilidade do ciclo de vida de produtos. / Life cycle management (LCM) is an approach for continuously improve the sustainability performance in organizations and its products through the incorporation of life cycle thinking in business practices. However, there are few management instruments to support this approach. Aiming to meet this demand, the purpose of this study is to analyze the relationship of LCM with Business Process Management, which aims at continuous improvement of organizational activities. A systematic literature review was conduct to identify BPM and LCM definitions and practices, which were used to define BPM and LCM and to analyze the relationship between practices and business process. Additionally, a bibliometric study was conducted to identify relationships between the two areas and its results shows that there are no conceptual framework shared between two. In constrast, the results indicate that BPM practices are related to business processes and organizational performance, and that many LCM practices are being applied into business processes, thus having an indiredt relationship between approaches. In addition, opportunities related to theory and practice are indentified: BPM has a set of practices for the management and improvement of process based on strategic planning, while LCM has elements and practices aimed at sustainability of the life cycle of products.

Companies have begun to change many of their processes in order to meet environmental demands made by governments and consumers. Two points of major concern are: the way these goods are produced and the impacts they cause to the environment, society and economy. Based on the theories of Marketing, Consumer Behavior, Social Responsibility, Product Development and Analysis of Environmentally Product Life Cycle, it was possible to determine important issues for which a product is considered environmentally responsible. Understanding these concepts, a case study was made in the company Philips, in Brazil, and its line of products from Lighting Home. The objective of this study was to analyze and evaluate the concepts and practices, and to verify if the fluorescent lamps may or may not be considered green products / Os assuntos desenvolvimento sustentável e mudanças climáticas tornaram-se recorrentes no dia-a-dia de toda sociedade e não são mais exclusivos de cientistas e pesquisadores. As empresas passaram a modificar muitos de seus processos em função de exigências ambientais feitas por governos e consumidores. Dois pontos de grande preocupação são: a forma como os diversos bens de consumo são produzidos e os impactos ambientais que eles exercem no meio ambiente, na sociedade e na economia. Esta dissertação concentra atenções na importância do desenvolvimento de produtos e em seus ciclos de vida, levando em consideração os possíveis impactos provocados na natureza. Com base nas teorias do Marketing, Comportamento do Consumidor, Responsabilidade Social, Desenvolvimento de Produtos Ecologicamente Corretos e Análise de Ciclo de Vida de Produto, foi possível determinar aspectos importantes para que um produto seja considerado ambientalmente responsável. A partir da compreensão dos conceitos, estudou-se o caso da empresa Philips no Brasil e a sua linha de produtos de Iluminação Residencial e Decorativa a fim de analisar e avaliar os conceitos e as práticas, e se as lâmpadas fluorescentes podem ou não ser consideradas produtos verdes

Industrial companies that carry on innovation and operation must have well-organized and capable business systems and processes. Customer needs, market demands, global competition and technological changes drive the companies to be more adaptable, flexible and dynamic. By working in network structures as extended enterprises, the companies face new possibilities and new challenges. Design, manufacturing and delivery of high quality products to competitive prices to the customers are essential for industrial companies. Holistic view of the product life cycle from technology development, via product and business system development and realization, to business operation, is important for sustainable industrial companies. A company with engineering and manufacturing of products in a business context needs to have effective innovation of business system and process. Business innovation encompasses the area from business idea to business operation and includes customer demands and solutions. The main part of business innovation is development of the product platform including product and support structures. Product variants are created and realized by various configurations of products and production systems. The thesis is elucidating that business innovation can be carried out by working in a systematic and structured way and by utilizing engineering design theories and methods. The business models, based on a new theory with a new navigation tool for interactions, are describing which activities should be performed in business innovation with product platform development and product structuring. For companies in business with changes, innovations can create new markets and products. Well-managed and innovative companies have good possibilities to be competitive in a tough business environment. The creation of business innovation models has been carried out according to a hermeneutic research method. The research work followed the hermeneutic circle or spiral. The thesis introduces a new dimension to the design area, namely business innovation or engineering, corresponding to business design and development. Business innovation is also a new type of innovation, combining technological, product, process, market and organizational innovations in industrial companies. / QC 20100920

Closed-loop supply chains (CLSCs) that integrate the activities for reclaiming residual values in postconsumer products with the traditional forward supply chain activities are important from financial and environmental perspectives. This thesis develops models and analyses on three topics novel to the field of CLSC research with a goal of advancing knowledge about effective decision-makings in CLSCs. In the first part of the thesis, we study joint control of stochastic forward and stochastic reverse material flows in CLSCs. With an application to a CLSC where postconsumer products are collected for warranty service purposes, we demonstrate that the benefit of coordinating two production activities could be significant. We develop a model that can be used to obtain an effective inventory control policy for coordinating forward and reverse material flows. Through Monte Carlo simulation and global sensitivity analysis, we identify major influential factors that affect system's warranty cost savings performance. The results indicate that joint control of forward and reverse material flows greatly improves warranty cost savings performance as well as system's robustness to uncertainties. The second part of the thesis develops a differential game model for characterizing decentralized time-varying competitive decision-making in a CLSC. The differential game model is particularly useful for studying time-varying interactive decision-making in CLSCs that involve many stakeholders who pursue different objectives in forward and reverse production activities. We identify optimal prices and production strategies that evolve over time under fluctuating market demand. Also, the model provides a quantitative scheme that can be used to obtain an efficient apportionment of product recovery processes. The third part of the thesis describes the relationship among consumers' risk-aversion, product cannibalization of new products by remanufactured products, and growth of CLSCs through price optimization models. Whereas price is one of the most effective variables for managing market demand, previous CLSC research has mainly focused on operational problems without paying much attention on the interface between CLSCs and markets. We develop models that jointly determine optimal prices in forward and reverse channels considering consumers' willingness-to-pay (WTP) for remanufactured products, consumers' willingness-to-accept (WTA) for a buyback price, and consumers' risk aversion to uncertain quality perceptions. The results show that consumers' active participation in CLSC is an important factor for the viability and growth of a CLSC. Also, we show that companies can benefit from product remanufacturing although it may be accompanied by production cannibalization.

As the architecture and construction industry places an increased emphasis on sustainability, building researchers are seeking more comprehensive methods to evaluate and reduce a building's environmental impacts. Life Cycle Assessment (LCA) has emerged as one of the most capable tools to aid in this assessment. Presently there are no guiding principles for the use of LCA in the building industry. This thesis aims to provide guidelines to help architects utilize LCA methodology as part of the design process. This study reviews a number of previously-completed whole-building LCA case-studies to understand different LCA scenarios of use in the building industry. In addition, a set of North American and international LCA tools were evaluated for their utility in different scenarios. The state of research was assessed to find answers to some critical issues concerning LCA. Based on these analyses, a number of scenarios of use of LCA were identified and a set of guidelines was proposed to conduct LCA for buildings. It was concluded that the present use of LCA is limited due to limited tool capabilities, deficient databases and lack of a building-specific methodology. The study recognizes these limitations and recommends specific research opportunities for future researchers. However, it is concluded that approximate LCA results obtained from the tools available today can be useful in informing design-decisions, keeping in mind the lack of precision in the results.

Traditionally, environmental impacts of man made products have been determined by performing a life cycle assessment (LCA) on the product. As the name implies, LCA is usually covers the entire life of the product in a so-called "cradle-to-grave" assessment. In determining environmental impacts over the whole product life, LCA's are reasonably adequate. However, in providing detailed impacts on a particular phase of life, LCA's are lacking. Detailed assessments are important because very few stakeholders have influence over a product during all phases of life. Stakeholders need detailed impact assessments in their particular phase of life. More detailed assessments give stakeholders more information that can be used for better environmental management (EM) and more environmentally benign operations. In many LCA's, the manufacturing phase of life has been over-generalized and over-simplified because of its relatively small environmental impact, as compared to other phases of life. Nevertheless, certain stakeholders, such as manufacturing companies, need detailed impact information for the manufacturing phase of life so that they can create a more sustainable manufacturing process. Most traditional LCA's use a case-based approach, which was deemed to be inadequate. For these LCA's, the information provided for each case is often quite detailed and specific. However, this makes the assessment less flexible, limiting the quality of the assessment to the degree that the current scenario matches the existing cases. In order to make a more user-specific assessment, a model-based approach was used. To give the model flexibility, a parametric model was created based on mathematical equations that represent various parts of the manufacturing process. To give the model structure, an activity-based costing (ABC) approach was used. Using the ABC structure, the manufacturing process was broken down into activities, each of which was characterized by mathematical models. Large models would be difficult to construct and simulate by hand, so a model was built with the aid of a computer. The modeling language SysML (Systems Modeling Language) was used to create an object-oriented model of the manufacturing process, using the ABC structure. SysML defines overall properties and behaviors of the various elements in the model, while the plug-in tool ParaMagic was used to execute the model via a Mathematica Solver. The model computes carbon dioxide emissions, energy consumption, and waste mass generation for a particular manufacturing scenario. The goal of the model was to quantify environmental impact factors in order to aid manufacturing stakeholders in EM. The overall goal of the research was to determine whether an activity-based, object-oriented model was a valid approach, and whether the computer-aided tools adequately implemented this approach. Findings show that SysML is capable of modeling large and complex systems. However, due to some limitations of Paramagic, only some of SysML's capabilities were utilized. Nevertheless, Paramagic is capable of extracting information out of a manufacturing model built in SysML, and solving parametric relations in Mathematica in a timely manner. Timely solutions of complex models are critical for stakeholders keeping a competitive edge.

As the green movement begins to sweep through the construction industry, decision-makers are beginning to include a sustainable aspect to their purchase decisions. Selecting a product solely based on its sustainability, however, is not enough to drive product selection in the construction industry. Cost still dominates the selection of building products. The level of sustainability of a product and its cost are not interconnected as market prices do not reflect the cost of environmental impacts, such as the cost of global warming or fossil fuel depletion. Having two distinct aspects to consider adds complexity in the product selection process. Typically, it constrains decision-makers to perform a trade-off analysis that does not necessarily guarantee the most environmentally preferable purchase decision. This study proposes a life-cycle management (LCM) system that reinforces the choices made by decision-makers by providing a scientific justification for those decisions. The proposed system analyses the environmental and economic performance of building product through life-cycle analysis and purchase price analysis. It operates on tools publicly available in the market and state-of-the-art analysis, assessment, and interpretation methods. The LCM system combines two distinct product attributes into a single performance score that can be easily interpreted. It allows decision-makers to compare product scores and ultimately make the most environmentally responsible and financially viable selection. A comprehensive approach is used to refine and test the LCM system using case studies comprised of an environmental and economic performance evaluation of flooring products. The contribution of this research includes the consideration of a holistic approach to product selection based on environmental and cost performance. Pre-construction estimators and construction managers could improve their estimating and product selection practices using the proposed system. Material suppliers can also benefit from this approach, as they can use it to enhance their pricing strategies, marketing plans, and overall product competitiveness.

Sediment control devices (SCDs) are critical to reducing the contamination of waterways from adjacent construction sites. Perimeter sediment controls retard the flow of surface runoff water originating on site and subsequently reduce solid, nutrient, and metal concentrations suspended in the flowing water. Silt fence is a commonly used SCD comprised of geotextile filter fabric, steel or wood support posts, and wire mesh reinforcement. The Georgia Department of Transportation (GDOT) uses an extensive amount of silt fence every year, and because of high degradation of geotextile in the field, the silt fence installations are rarely recycled. This research measures the performance of five SCDs (two types of silt fence, mulch berm, compost sock, and straw bales) at suspended solid, turbidity, nutrient, and metal reduction. A life cycle analysis (LCA) is performed to identify environmental impacts associated with material production, assembly, installation, use on site, and disposal. An impact analysis is performed according to for each SCD. Results of the impact analysis are compared to determine the SCD with lowest overall environmental impact. Results of the SCD performance study show that silt fence installations performed the best at reducing suspended solids and turbidity, mulch was best at reducing nutrients, and compost was the best at reducing metal concentrations. The life cycle impact analysis indicates that a mulch berm is the SCD with the lowest overall environmental impact. The impact analysis included global warming potential, acidification, eutrophication, and aquatic toxicity.
