摘　　要：着色Petri网作为一种高级Petri网,由于引入了时间,颜色集,层次结构等概念,使之更适合对大型复杂系统的仿真模拟与性能分析。CPN Tools支持各种随机概率分布,可以在模拟过程中提取各种数据,生成各种不同的性能分析结果,并支持连续模拟,分析,从而可以对现实系统进行更加精确的仿真。利用CPN Tools模拟过程中为CPN模型定义各种数据采集器,可以得到更加准确的性能分析报告。本文通过一个对快餐店进行仿真以及性能分析的简单的例子说明了着色Petri网的特性与CPN Tools的仿真与性能分析方法。As an advanced Petri net, the colored Petri Net is well suited for modeling and analyzing large and complex systems for importing some concepts such as time information, color sets, hierarchical models etc. CPN Tools include support for generating random numbers from different distributions, for collecting data during simulation, for generating different kinds of performance - related out- put, and for running multiple simulation replications. We can make a precise simulation of real world phenomena using CPN, and have an accurate performance analysis by defining some monitors in CPN Tools. To illustrate the CPN and the usability of CPN Tools, we give a simple example of simulation based performance analysis by analyzing a noshery.
