针对现有时序逻辑在对复杂不确定时间信息描述和推理方面的局限性,构造了直觉模糊时间Petri网模型(IFTPN)及其推理方法.该Petri网模型利用直觉模糊集合对模糊时延、模糊时间片进行描述,可以表达定义在离散论域或连续论域的各种不确定时间信息,并基于直觉模糊逻辑定义了模糊时间运算法则;同时,基于线性逻辑对该模型进行描述,定义了变迁之间的各种触发规则,并给出了推理方法.将该方法应用于C4ISR系统进行决策时延分析,表明了该模型及其推理方法是比较优越的. In view of the limitation of the existing sequential logic in the description and reasoning of complex uncertain time information, an intuitionistic fuzzy time Petri net model (IFTPN) and its reasoning method are constructed. The Petri net model uses fuzzy intuitionistic fuzzy set to evaluate the fuzzy delay, fuzzy Time slice, we can express various uncertain time information defined in discrete or continuous domain and define fuzzy time algorithm based on intuitionistic fuzzy logic. At the same time, the model is described based on linear logic and the transition is defined , And gives the reasoning method.This method is applied to the C4ISR system to analyze the decision-making delay, which shows that the model and its reasoning method are superior.
