Abstract
GQFD-II (Green Quality Function Deployment II) is an innovative methodology for developing environmentally conscious products. However, GQFD-II has several shortcomings that make it difficult to use. GQFD-II depends on a detailed and time consuming LCA (Life Cycle Analysis) that requires designers to have a comprehensive understanding of environmental science. Further, product comparisons made using GQFD-II rely on a complex decision making algorithm that lacks a coherent quantitative basis. To address these shortcomings, GQFD-III has been developed. In this paper, a methodology for Life Cycle Impact Assessment is integrated into the Green House, and AHP (Analytical Hierarchy Process) is used for selecting the best product concept. Finally, the GQFD-III methodology has been illustrated using an example in which three coffee makers are compared in terms of quality, cost and environmental performance. Further research needs to be done for developing a DSS (Decision Support System) based on the GQFD-III methodology. This can help a design team to concurrently consider the quality, cost, and environmental aspects of products early in the design stages, thereby resulting in reduced product development times.
