Abstract
In recent manufacturing technologies, it is very important to satisfy environmental and economical requirements simultaneously. As an answer to the situation, the authors have proposed a new product efficiency index named "total performance index (TPI)" and a procedure of analysis based on the proposed index. The analysis named "total performance analysis (TPA)" is a powerful tool in determining design strategies of "green products". At the same time, manufacturing processes for those green products should be also environmentally benign. In this paper, the authors try to apply the TPA to a series of manufacturing processes. Through the effort, a procedure to evaluate manufacturing processes and to obtain suggestions for process improvement is shown. By using the procedure, designers will become able to determine which process combination is really "eco-efficient".
