Abstract
This paper deals with a new agent system that promotes reuse and recycle processes by retrieving product and market information, presenting information for lifecycle option, and supplying contract procedure. With respect to some kinds of electrical products and cars, particular recycle systems have been built by government in Japan. However, regarding other products, users' activity for reuse and recycle is a necessary factor to increase recovery rate. In this paper, a new agent-based information system that supports the users' reuse and recycle activities with interaction among user, product and market is proposed. The system includes an interface agent that changes the behavior to adapt to user property. Each agent behavior is defined and whole agent interaction is shown. And the realization of this system is discussed with a case study using a developed prototype system.
