摘　　要：Petri网具有优势,比如同步、并发、冲突等特点,因此可用来对复杂系统进行建模。但是在复杂的系统建模过程中,设计者会常遇到子系统的合成问题,本文介绍了一种共享P-型子网的合成。本文以楼宇门禁系统为例,分析了门禁系统的各种情况及该情景下的Petri-网模型,最后根据各个Petri子网的特点,采用了共享P-型合成方法,合成为一个系统的整体建模图。The superiority of the petri-net is obvious, such as synchronization、concurrency and conflicts. It is suitable to model those complex information systems. But designers often have trouble synthesizing in some sub-systems. This article tells a method to synthesize the shared P-type subnet.An entrance guard system is used for illustration. In this case, some cases of this system are analyzed and modeled with Petri-net. According to features of subnets, we synthesized them to an integer system with the shared ...
