Logistics Enterprise Business Process Optimization And Simulation Based On Object-Oriented Time PETRI Nets

With the rapid development of economy, more and more enterprises informatization construction, information technology introduction enterprise business flow changes。New process before implementation, needed to evaluate the process to implement the new process, the rationality, modeling and simulation can be very good solution to this problem, this paper puts forward a method for business process modeling method Petri Nets,using this method to analyz the modeling and simulation.This paper firstly review business process research situation at home and abroad , and puts forward the problems in information technology based on the research of the logistics business process optimization and simulation. Petri nets modeling simulation by reference to the relevant literatures, this paper puts forward a method based on object-oriented time Petri nets of modeling method, this method overcomes Petri nets modeling the complexity of the general shortcomings. Using object-oriented method, can put the content and methods of data processing in Petri nets model housed in a Petri nets for a single object, content and method of the internal model for other objects of the changes will not affect. Then the method established Petri nets model of logistics distribution, and the relevant theory of Petri net model is analyzed, the model is correct, usable.Using the proposed modeling method, this paper establishment Petri nets model based on the business process of logistics station. The stations are implementing enterprise informatization and designing business processes. Establishing Petri nets model of the station's business process, and the model analysis, it is proved the validity of the model, the usability. To cycle time as parameter, use ExSpect software simulation model. Through the analysis of the results, establishing the Petri nets optimization model for simulation software. According to the evaluation standard, comparing two simulation results verify the optimal degree of optimization model,which reflects the object-oriented Petri nets better for business process modeling.
