【摘要】 针对当前工作流模型仿真方法的不足,提出了一种基于WF-net网的扩展WF-net的工作流模式模型,并对模型进行验证与仿真。首先讲述工作流网(WF-net),然后从时间和层次两方面对基于WF-net的工作流模型进行扩展研究,提出了扩展WF-net工作流模型,并对该模型进行仿真调度策略和冲突解决策略进行选择,给出了某产品开发过程的扩展WF-net工作流模型,设计了扩展WF-net工作流模型仿真流程。为了增强模型仿真的可信度和可视性,从Petri网到扩展WF-net工作流网算法和仿真流程,经过仿真可知该模型没有死变迁,是正确的工作流模式模型。更多还原

【Abstract】 To overcome the shortage of workflow model for the current simulation methods,we propose a network based on extended WF-net workflow model,the model validation and simulation.In this paper,the WF-net workflow is described.And then,the WF-net is extended both with the time and level.The simulating scheduling strategy and conflict resolution strategy are selected,and the expanded WF-net workflow model for the product development process is given.The extended WF-net model for simulation of the workflow process is designed.To enhance the credibility and visibility of the simulation model,the workflow net algorithm and simulation processes are extended from the Petri net to WF-net.Through simulation,it can be seen that changes in the model are not dead transition,and it is a right workflow model.更多还原
