Environmental issues have become an imperative for most modern companies. They are under pressure on making the product development process compliant with recent green directives. Product structure is recognized as a critical factor for reducing environmental impact in product end-of-life. However, most previous studies failed to leverage the latitude at the design stage due to the assumption of a fixed product structure. We propose a CAD-supported tool that allows automatic variation of 3D product structure by combination of parts, selection of assembly method, and re-arranging the assembly sequence. A GA-based optimization scheme is developed to produce a better product structure corresponding to lower assembly/disassembly costs, while fulfilling with given recycling and recovering constraints. The results implemented in a commercial CAD system demonstrate the practicality of this work in computer-aided green product design.
