Extending the DEVS formalism toward Geometrical Kinematic Modeling and Simulation for Virtual Manufacturing Environment

가상제조환경을 위한 형상기구학 모델링 및 시뮬레이션으로의 DEVS 확장

Proposed in this paper is a modeling and simulation methodology for a virtual manufacturing environment. Based on DEVS formalism[Zeigler 76], the proposed model, so called GKDEVS, is designed to descript the geometrical knematic structure as well as event-driven and continuous state dynamics. In terms of abstract simulation algorithm[Zeigler 84], the simulation method of GKDEVS is proposed for combined discrete-continuous simulation. Using the GKDEVS, and FMS model consisting of a turing machine, a 3-axis machine and a RGV-mounted robot is constructed and simulated.
