Book Description
Low-carbon design is a sustainable method, which coordinates the carbon footprint, cost and performance of each stage in product lifecycle from the design source to satisfying low-carbon demand. It is also a significant technology to reduce the carbon emission before manufacturing. To effectively and efficiently reduce the carbon emission, a low carbon-oriented design method is studied in product lifecycle.

Book Description
This dissertation contributes to the sustainability literature by incorporating a systematic analysis to provide guidelines to sustainable design. During the design phase, there is a great potential to manage the environmental impacts of the whole product life cycle. However, decision making in the design phase is usually complicated. Therefore, a holistic system analysis with the consideration of relevant factors in the whole product life cycle is needed. In this dissertation, a life-cycle thinking framework is applied to solve the supply chain network design problem and the product durability design problem. In Chapter 2, an integrated supply chain network design problem is studied. We built optimization models to minimize the carbon emission and/or the cost of a three-tiers supply chain network. The carbon emissions associated with major supply chain activities, including transportation, warehouse construction, and warehouse operations, are characterized and included into the optimization models. The decisions in the models include transportation mode, shipping frequency, warehouse locations, warehouse capacity, and warehouse-retail store assignment. We transformed the problems into second-order conic programs to reduce the computation time. Several model variations, including multi-objective program and bi-level optimization model, are also studied to understand the trade-offs between cost and carbon emissions and provide sustainable guideline for supply chain design in real-world scenarios. In Chapter 3, the product durability design problem is analyzed. We constructed a mathematical model to understand whether Design for Durability strategy is always good for the environment or not. In the study, the energy consumption during the manufacturing phase, the use phase, and the remanufacturing phase is considered. The bass diffusion model is adapted and modified in the study to enable the construction of the relationship between new manufactured products and refurbished products. Analytical results confirm the common beliefs that a more durable product consumes less energy in the special case with no repeat purchases. A numerical analysis for the general setting identifies the main factors of the optimal product life when we want to minimize the average energy per item per unit time. We also provide exploitation on the various trade-offs of increasing durability to better understand optimal product durability design. In Chapter 4, we discussed a promising future direction on incorporating Life-Cycle Assessment (LCA) uncertainty into decision making processes. LCA uncertainty has gathered great importance in recent years. Researchers have argued that, without incorporate the uncertainty analysis, the decision made based on a single and deterministic LCA result may be unreliable. Quantitative uncertainty analysis is needed to incorporate the uncertainty level into decision making processes. However, due to the time and cost constraints, it is not always feasible to conduct a complete LCA study with uncertainty analysis. It becomes a challenge to quantify the uncertainty level of a LCA study when only limited secondary data is available. We proposed a future work direction that could remedy the drawbacks of current methodologies.

Book Description
Environmental Carbon Footprints: Industrial Case Studies provides a wide range of industrial case-studies, beginning with textiles, energy systems and bio-fuels. Each footprint is associated with background information, scientific consensus and the reason behind its invention, methodological framework, assessment checklist, calculation tool/technique, applications, challenges and limitations. More importantly, applications of each indicator/framework in various industrial sectors and their associated challenges are presented. As case studies are the most flexible of all research designs, this book allows researchers to retain the holistic characteristics of real-life events while investigating empirical events. Includes case studies from various industries, such as textiles, energy systems and conventional and bio-fuels Provides the calculation tool/technique, applications, challenges and limitations for determining carbon footprints on an industry by industry basis Presents the background information, scientific consensus and reason behind each case study

Book Description
Interest in accounting for environmental impacts of products, processes, and systems during the design phase is increasing. Numerous studies have undertaken investigations for reducing environmental impacts across the product life cycle. Efforts have also been launched to quantify such impacts more accurately. Life cycle energy consumption and carbon footprint are among the most frequently adopted and investigated environmental performance metrics. As efforts continue to incorporate environmental sustainability into product design, struggles persist in concurrent consideration of environmental impacts resulting from the manufacturing processes and supply chain network design. Thus, the objective of this research is to present a framework for reducing product cradle-to-gate energy consumption and carbon footprint through simultaneous consideration of manufacturing processes and supply chain activities. The framework developed in this thesis relies on unit process modeling, and is demonstrated for production of a bicycle pedal. It is shown that simultaneous consideration of manufacturing and supply chain processes can impact decision-making and improve product environmental sustainability at the design stage. The work presented contributes to the state of the science in sustainable design and manufacturing research. In addition, a point of departure is established for the research community to move current efforts forward for concurrent consideration of multiple stages of the product life cycle in pursuit of environmental, economic, and social sustainability.

Book Description
It is quite an onerous task to edit the proceedings of a two week long institute with learned contributors from many parts of the world. All the same, the editorial team has found the process of refereeing and reviewing the contributions worthwhile and completing the volume has proven to be a satisfying task. In setting up the institute we had considered models and methods taken from a number of different disciplines. As a result the whole institute - preparing for it, attending it and editing the proceedings - proved to be an intense learning experience for us. Here I speak on behalf of the committee and the editorial team. By the time the institute took place, the papers were delivered and the delegates exchanged their views, the structure of the topics covered and their relative positioning appeared in a different light. In editing the volume I felt compelled to introduce a new structure in grouping the papers. The contents of this volume are organised in eight main sections set out below: 1 . Abstracts. 2. Review Paper. 3. Models with Multiple Criteria and Single or Multiple Decision Makers. 4. Use of Optimisation Models as Decision Support Tools. 5. Role of Information Systems in Decision Making: Database and Model Management Issues. 6. Methods of Artificial Intelligence in Decision Making: Intelligent Knowledge Based Systems. 7. Representation of Uncertainty in Mathematical Models and Knowledge Based Systems. 8. Mathematical Basis for Constructing Models and Model Validation.

Book Description
Environmental Life Cycle Assessment (ELCA) that was developed about three decades ago demands a broadening of its scope to include lifecycle costing and social aspects of life cycle assessment as well, drawing on the three-pillar or ‘triple bottom line’ model of sustainability, which is the result of the development of the Life Cycle Sustainability Assessment (LCSA). LCSA refers to the evaluation of all environmental, social and economic negative impacts and benefits in decision-making processes towards more sustainable products throughout their life cycle. Combination of environmental and social life cycle assessments along with life cycle costing leads to life cycle sustainability assessment (LCSA). This book highlights various aspects of life cycle sustainability assessment (LCSA).
