Applications Of Workflow Based On Petri Net

Workflow is an auto-executive flow which can fully or partly execute, according to the flow rule, it transfers or auto executes the information that the task and the task referenced among different executants. Workflow management system is a software system, which uses to define the flow and instance management, and also logically executes the flow instance that defined by the system in advance.Logistics management software is a new hotspot, and will develop fast in the future years. In technique parts, logistics management software becomes more and more mature, compensative and open. In product's characteristic, it becomes more specialization and its functions are more comprehensive. The old logistics management software is just simulating the business process, and not interacts well. Once the business changes, the old system could not meet the new requirements, because of the environment and other discommodious factors, update the old system will be fairly complex. The Workflow not only avoids the situation, but also standardizes the business work and properly deploys the workers and resources; accordingly, improve the work efficiency and competition.In the thesis firstly from the study discussion to understanding the Petri net and workflow technology relevant theory, secondly depth analysis of the logistics company's basic business processes, on the basis of Petri nets used for these processes to establish a mathematical model, thirdly from the technical designed workflow management system platform logistics ITMS.
