The problem addressed in this research was to develop an approach for the simultaneous green design of products and associated manufacturing processes including demanufacturing concerns. We propose a generic approach called Integrated Environmentally Conscious Design and Manufacturing (IECDM) which can be applied to address problems in the ECDM domain. IECDM incorporates environmental considerations into the engineering design process, thereby increasing a product's total life-cycle value (including its end-of-life value) as experienced by the customer, manufacturer, and society, while simultaneously reducing impacts on the environment caused by that product and its manufacturing processes. IECDM is a novel integration of Quality Function Deployment (QFD), Life-Cycle Assessment (LCA), Multiple Criteria Decision-Making (MCDM), and Cost-Benefit Assessment (CBA). The focus is on process, based on modification of the traditional QFD methodology to incorporate environmental issues and green product-design decisions through the life cycle design activities of synthesis, analysis, and evaluation.

This dissertation presents a QFD-based IECDM approach, a mathematical CBA model, and an IDDS (Integrated Design Decision-Support) framework with a design-flow-chart application for incorporating environmental criteria into product and process eco-design. The IECDM problem is defined as: given the customer and environmental requirements, develop an integrated approach for green product design that results in maximization of the product's total life-cycle value (TLCV). Initially. through investigation in the field of ECDM, we specified a clear ECDM domain within Industrial Ecology. Then. we proposed various state-of-the-art techniques that were used to implement ECDM in the literature. After we defined the IECDM problem. we developed an integrated approach that led to a generic QFD-IECDM methodology for dealing with problems in the ECDM domain. Finally, for implementing the proposed methodology, we developed a tentative IODS framework to encourage long-term development followed by an example.
