"Reuse" is an important life cycle option for constructing close-loop product life cycles, since it can preserve values of parts and modules. In order to clarify issues of reuse, this paper proposes an indicator "marginal reuse rate, " which is defined as a rate of overlapped area of sales curve and disposal curve against total sales amount of a product. The rate indicates theoretical upper limit of reusability. After formalizing the marginal reuse rate, this paper analyzes some product life cycles using the rate. These analyses clarified that increase of collection rate and extension of sales period are effective for increasing the rate in case of rapid product life cycles, and multi-generation design and life cycle management are effective in long-life product life cycles.
