Distributed simulation model for computer integrated manufacturing

Abstract

In this paper, we firstly discuss the necessity of a sirnulation tool which can handle a large and complex manufacturing system under CIM environment, and then consider problems itlcurred by developing such a large system model. A distributed simulation model developed on a distributed computer system is then shown to be a promising method to cope with the problems. Lastly, a time bucket method with time warp mechanism is proposed for the synchronization of the distributed simulation and its computational features are investigated by modeling a virtual factory on six workstations connected by the ethernet.

A modelling formalism for distributed manufacturing simulator

“…The integration of manufacturing system now in progress made it crucial to operate the system efficiently as a whole. Distributed simulation system is one of the most important concepts to support the effective operation for a large-scaled manufacturing system (Fujii, 1992(Fujii, , 1994(Fujii, , 1996. In the previous works, we have proposed i) simulation engine architecture and ii) synchronisation mechanism, in distributed environment.…”
