| Research Abstract |
In the manufacture of industrial products, utilization of reusable parts recovered from used products makes the environmental impact of manufacturing be reduced compared to utilization of brand new parts. It is important that the eco-efficiency incorporating the concept of efficiency should be enhanced rather than the absolute reduction of environmental impact for sustainable growth. In this study, industrial products consisting of reusable and brand new parts are assumed to be in the open-loop and closed-loop circulation system. Effect of physical life distribution of reusable parts on the eco-efficiency is investigated with the consideration of cost constraints, and the optimal physical life distribution maximizing the eco-efficiency is studied.
