ライフサイクル・シミュレーションによる物質循環の費用/便益分析

抄録

This paper describes a method of cost-benefit analysis of recycling and/or reusing by life-cycle simulation of products. This method uses colored petri nets to model : the streams of objects (i.e., products, subassemblies, parts, materials, and so on) throughout the life cycles of products ; the streams of money among companies concemed with the life cycles ; and the control of the streams. The simulation using the model reveals whether the objects are recycled and/or reused without being stockpiled and whether each company concemed with the life cycles obtains a profit. The life-cycle simulation for a copier drum composed of three materials is presented as a validation example.
