The Purpose of this paper it to solve optimization problems for locating plant sites as a first step of investigation of social distribution problems, which are actually presented in some company. We construct a productivity-oriented method for an optimal plant site selection taking into considerations trade-off theory between production cost and outgoing transportation cost including production operation level. In future, we try to develop this model to a more general one suited to optimization problems of social hub such as central hub and local hub in a broad area and investigate a construction of optimal hub system as a social infra.
