In order to optimally manufacture large-scale componential product by large-scale component methodology, a system of Advanced Manufacturing (AM) and Advanced Manufacturing Simulation (AMS) in Open Grid Computing Environment (OGCE) was proposed. Based on the concept of dynamically changing the scale, simulations during the design & development of larger-scale component manufacturing products, of production line and process, of manufacturing enterprise modeling and performance, and of advanced manufacturing processes could be rapidly solved by the proposed system. The software architecture and framework of the system consist of such several basic components as Paralleled Virtual Machine (PVM)/HARNESS, DoD Defense Modeling & Simulation Office (DMSO) High Level Architecture (HLA)/Run Time Infrastructure (RTI), grid computing simulation, etc.. Then, the simulation model of the system was computed rapidly by the method of Zone Decomposition & Combination. At last, this proposed simulation system was compared with three popular simulation software systems.
