Abstract
From the viewpoint of long-term usage, modular product has been attracting attention. On this study, a virtual market simulation system for evaluating the sustainability was proposed. First, production system model that consists of platform and add-on modules is introduced. Then to realize long-term usage of modules, we focused on user's different sense in value, and we proposed trading in the market using the difference between the values of the individual user feels for the same module. Finally, we construct multi-agent simulator which consists of plural user agents with the different value concepts and modules producer agent. From the results of case study, feasibility of evaluating sustainability was showed.
