Abstract: In this paper, we use bierarchical and colored Petri nets to model physical distribution system of the Bao Steel Group, we also proposed a method based on COM technology to simulate the physical distribution system, which provides modular and bierarchical conception to design general simulation distinctly. The propesed method can also be used in other physical distribution systems and FMS.
