Realization of resource circulation systems is recently desired. Thus this research aims to investigate conditions required to realize sustainable circulation systems, by means of making a product circulation model and applying life cycle simulation. A feature of this research is that a resource circulation system is modeled as interaction between agents with behavioral preferences. These agents include users and product makers in this model. Each user individually purchases products and each product maker individually supplies products. These actions are carried out through a market. Then some simulation scenarios were set up. These scenarios differ in behavioral preferences of product makers. Next, life cycle simulation was carried out in each scenario. As a result, the sale amount of products and environmental load in whole product life cycle were output. By means of comparing these results, it was possible to show the rational product development plan of product makers.
