Development of Flexible Manufacturing System using Virtual Manufacturing Paradigm Sung-Chung Kim* and Kyung-Hyun Choi School of mechanical engineering, Chungbuk National University, Cheongju, South Korea, School of mechanical engineering, Cheju National University, Cheju, South Korea ABSTRACT The importance of Virtual Manufacturing System is increasing in the area of developing new manufacturing processes, implementing automated workcells, designing plant facility layouts and workplace ergonomics. Virtual manufacturing system is a computer system that can generate the same information about manufacturing system structure, states, and behaviors as is observed in a real manufacturing. In this research, a virtual manufacturing system for flexible manufacturing cells (VFMC), (which is a useful tool for building Computer Integrated Manufacturing (CIM),) has been developed using object-oriented paradigm, and implemented with software QUEST/IGRIP. Three object models used in the system are the product model, the facility model, and the process model. The concrete behaviors of a flexible manufacturing cell are represented by the task-oriented description diagram, TID. An example simulation is executed to evaluate applicability of the developed models, and to prove the potential value of virtual manufacturing paradigm. Key Words : FMS, virtual manufacturing system, CIM, object-oriented paradigm, TID Recent trends in manufacturing systems, such as the need for customized products by small batches and for fast product renewal rates, have been demanding new paradigms in manufacturing. Therefore, the modern manufacturing systems are needed to be adaptable, and have the capability to reconfigure or self configure their own structure. Flexible Manufacturing Cells (FMCs) are generally recognized as the best productivity tool for small to medium batch manufacturing, and are also basic unit to construct a shop floor which is an important leve for developing computer
