Collaborative Workflow Management Technology In Product Development, Research,

Workflow management in cooperative product development environment is the enabling technology, which is used by modern manufacturing enterprises to carry out the stratagem of distributed web-based manufacturing. Cooperative product development is the main characteristic of modern enterprises organizing production in the web-based manufacturing environment, which is in favor of shortening the product developing cycle, reducing the cost, improving the quality and finally succeeding in the market competition. By using the workflow management system, modern enterprises can manage and optimize business process efficiently and can realize the requirement of "sending correct participants the correct information at the correct time" in product development environment. The workflow management technology has gained popularity in enterprises and researching fields.Based on the analysis of the feature of cooperative product development and the function structure of workflow management system, the architecture of workflow management system in the cooperative product development environment is set up in this paper, which is the foundation for other parts of this paper. The distribution of workflow is the main characteristic of the workflow technology in the web-based environment.Based on the theories of Petri nets and object oriented technology, this paper imports factors of time and sets up model of Object Oriented Timed Petri Net. Workflow model of Object Oriented Timed Petri Net has many analyzing methods, which are used to analyze the nature of Petri nets, such as liveness.Workflow executing service is the kernel function of workflow management system, which is responsible for the runtime control of workflow management system. This paper mainly discusses the formalization description of Event-Condition-Action(ECA) rules and its application in workflow runtime control.According to the research on the architecture of the workflow management system and its relevant technology, the realization method and the application of the system are introduced in the end.
