摘要
In this paper, a virtual factory is proposed in the form of a distributed simulation model which provides a tool for performance evaluation of large and complex manufacturing systems. The virtual factory is constructed on a computer network developed for computer-integrated manufacturing (CIM). The relationship between the structure of a distributed simulation system and the model of a manufacturing system is described, and then basic requirements for the virtual factory are presented. Several Time Bucket methods, called Single-Phased Bucket, Double-Phased Bucket and Modified Double-Phased Bucket, are proposed as a synchronization mechanism to construct a distributed manufacturing simulation system, and their characteristics and effectiveness are discussed from the viewpoint of modeling a manufacturing system.
