This paper proposes an integration test-bed system for supply chain management, which forms the foundation for the construction of a valued manufacturing chain. The core system of the test-bed is a hierarchical simulation system to support production management in supply chain. The testbed possesses sub-components linked with the simulation system. These are: 1) an enterprise integration model which represents business and information process in supply chain, 2) the communication data interface between the simulation and the suppliers companies, 3) the decision support system based on statistical methods. This paper describes the details of the system architecture and system configuration. After the detail description, the authors discuss simulation integration methodologies through an application example.
