基于模糊统计的模糊Petri网token确定方法

在模糊Petri网应用研究中,普遍存在模糊token由专家直接给出或主观假定的问题。基于这种情况,提出了通过模糊统计法来获得库所的模糊token,为成功应用模糊Petri网理论创造了条件。给出了计算模糊token的通用形式化算法。实例论证了模糊统计法在求取模糊token时的可行性与有效性。

In current application studies of fuzzy Petri nets,a commonly existing problem is that fuzzy tokens are assigned or supposed subjectively by experts. Based on this,it was proposed that fuzzy tokens of places are obtained by fuzzy statistics.This approach provides a basis for properly applying fuzzy Petri nets.A general formalized algorithm was given for computing fuzzy tokens.The presented instance confirms the feasibility and validity of fuzzy statistics in acquiring fuzzy tokens.
