Study Of Workflow Process Modeling Based On High-Level Petri Nets

Workflow technology is to achieve business process modeling, business process simulation analysis, business process optimization, business process management and integration, and eventually realize the automation of business processes of core technology. To-business approach to the use of workflow business process modeling and in-depth analysis can not only standardize business processes, business processes found unreasonable links, in turn, business process optimization of the reorganization, but also established its own business process model is a very important enterprise knowledge base and rule base, you can be the guiding enterprises to implement management information system computer model.Workflow technology for a more in-depth study, done by the main job is as follows:(1) System, introduced the basic concepts of Petri Nets, Petri Nets nature and commonly used analytical methods, the standardization of the workflow reference model, as well as architecture.(2) Described in detail based on the Petri Net Modeling Method, on how to set up workflow and based on this model is correct from the performance evaluation and modeling of two aspects of the workflow model of Petri Net analysis methods.(3) Enterprise business processes has become increasingly apparent that the complexity of the current characteristics and dynamic characteristics, the introduction of the level Petri Net Workflow Modeling Technology, and eventually use this technology to generate workflow Petri Net Models correctness verified.(4) Give the job flow time Petri Nets approximate performance analysis method, proposed the use of Workflow Petri Net model of the average job flow time performance analysis.(5) Finally to an enterprise logistics management system for example vividly describes how to use these methods on examples of workflow management system for modeling, analysis and evaluation, testing proved that the workflow system model can be a very good efficiency.
