A new circular production system for reusing general-purpose parts within a region as common parts for various products is proposed. The components of industrial products are classified into two types: general-purpose and specialized parts, of which the general parts are designed to be reused among multiple types of products and combined with the specialized parts manufactured using resources in the region. This paper evaluates the environmental and economic performance of the regional circular production system and clarifies the conditions for this system to be established as a sustainable business. A hybrid simulation system of life cycle simulation and agent-based simulation is developed for the evaluation focusing on the business activities in the circular production in a region. As a result of a case study, it was found that the regional circular production can be profitable even after five years by appropriately managing the sales price and the lifetime of the products.
