Abstract
Products affect the environment at many points in their life cycles Once a product moves from the drawing board into the production line its environmental attributes are largely fixed Many researchers have focused on developing intelligent systems to provide a variety of design and manufacturing information to help designers make environmentally conscious decisions However in the early design stage not all the information available is precise A large amount of information especially those that are based on designer experience is fuzzy in nature This paper presents an innovative method namely green fuzzy design analysis GFDA which involves simple and efficient procedures to evaluate product design alternatives based on environmental consideration using fuzzy logic The hierarchical structure of environmentally conscious design indices was constructed using the analytical hierarchy process AHP which include five aspects 1 energy 2 recycling 3 toxicity 4 cost and 5 material After weighting factors for the environmental attributes are determined the most desirable design alternative can be selected based on the fuzzy multiattribute decisionmaking FMADM technique The benefit of using such a technique is to effectively solve the design problem by capturing human expertise
