摘要
工作流管理是今年来发展最为迅速的计算机应用技术之一,被广泛应用于多个领域。Petri网,是对具有并发、同步、异步、冲突、资源共享以及不确定性等特点的离散事件系统进行建模的有效工具。针对工作流的性能评价问题设计和实现了随机Petri网仿真工具。介绍了工作流和随机Petri网的基本概念,然后具体介绍了仿真策略和冲突解决方法的关键仿真技术问题,最后结合具体实例对仿真工具的有效性和正确性进行验证。
Workflow management has become one of most rapidly developed technology in computer science and has been widely used in a lot of fields. Petri net is an effective model tool for discrete event system with the characteristics, such as concurrency, asynchronism, collision, resource sharing and so on. Aiming at the performance evaluation of workflow, designs and implements simulation Tool. Some of the basic concepts about workflow and stochastic Petri net are introduced. The key simulation techniques of simulation strategy and conflict resolution policy are then presented. An example was illuminated to show the validity and correctness of the simulation tool.
