Modular approach for Petri-net modeling of flexible manufacturingsystems adaptable to various task-flow requirement

摘要

A modular approach is presented for constructing Petri-net modelsfor a class of flexible manufacturing systems (FMSs) composed of atransportation vehicle and several functional groups of entities such asmachines and buffers. The resulting model preserves the geometriccharacteristics of the transportation subsystem as well as theflexibility of alternative routes for material flow in an FMS. Byseparating the machine-dependent part from the whole system, the finalmodel in a modular structure is adaptable to various task flowrequirements. In addition, the methodology can deal conveniently with areconfiguration of the transportation layout
