赋时着色Petri网在建模仿真中的应用

Application of Timed Colored Petri Nets in Modeling and Simulation

赋时着色 Petri 网(TCPN)在着色 Petri 网(CPN)基础上引入时间概念,更适于复杂系统建模仿真。其库所赋时实施规则同 CPN,变迁赋时实施规则将令牌移入变迁的输出库所。基于 TCPN 优先权服务排队系统,用 CPN的元语言实现优先权排队,由于时间引入,可真实模拟顾客到达时间和服务台服务时间。

Timed Colored Petri Nets (TCPN) is that the concept of time was added in Colored Petri Nets (CPN), and make TCPN is more suitable for the modeling and simulation of complex systems. The execution rule of TCPN is the same of CPN, the token is moved into transitional output library to shift timed execution rule. For TCPN model of the priority level service queuing system, the priority queuing was realized with CPN Meta-Language. Because of adding time, customer arrival time and service time was well simulated with TCPN.
