Logistics System Modeling Based On Four-color Petri Net

After researched overseas logistics theories and these correlative cooperativetechnique, this paper abstracted a whole business flow in the logistics system intothe stock flow, the funds flow, the ownership flow and the information flow,combined the theories knowledge of the Petri net at the same time, and puttedforward a new tool of modeling, four colors Petri nets for researching modernlogistics, to let these four flow to be in cooperation and to raise the work efficiencyof business flow.This paper built in the model about the logistics to bring forward a uniformgathering, distributing goods center in the industry district using four colors Petri net.In building the workflow model process about this logistics model, this paper set upthe conception model and accomplish parts of functions of logic model from theorganization model, the resources model, the process model and the informationmodels based on the technique about CSCW and workflow.In the process of building up the logistics system, this paper placed emphasis onresearching and describing the concept model and the logic model about theAuto-selecting system, the logic model about the basic organization unit of ordering,and the concept model about the logistics gathering and distributing the goods andsetting up the mold about the information model of each process. In addition, Thepaper set up the concept model about the machine managing resources.Finally, this paper discussed the bound, safety, consistency, live, etc in theAuto-selection system of the logic model about this uniform gathering, distributinggoods center.
