Abstract
Closing product life cycles without economic and environmental disadvantages is one of the important techniques to realize inverse manufacturing. Reuse of used products is one of the promising approaches to achieve these closed-loop life cycles. But it is difficult to secure a necessary amount of the used products, because when and how many products are disposed are entirely dependent on consumers' behaviors. To address this problem it is indispensable to deal with the flow of discarded products. In this paper we illustrate the life cycle simulation system assuming the model of consumer and discuss the strategy of facilitating reuse of used products considering the simulation result about the distribution of discarded product.
