Abstract: Petri net,a visual and mathematical object,can be used for dynamic behavior analysis.Several salient features are chosen from the multitude of existing extensions of Petri nets,and a new concept of aging tokens is introduced.The result framework provides for flexible and transparent graphical modeling with excellent representational power that is suited for system maintenance model.Finally,accordingly its rationality and advantage are proved by an example.

Key words: repair process, process modeling, Petri net, Stochastic Petri Nets with Aging Token(SPNAT)

摘要: Petri网是严格定义的数学对象,直观、形象,且可用于动态的行为分析。通过引进退化令牌对随机Petri网进行理论扩展,提出了一种基于退化令牌的随机Petri网(SPNAT)的维修过程建模与仿真方法。最后通过实例验证了该建模方法的有效性和优越性。
