Abstract: In view of the continuous changes of internal and external environment factors of supply chain system, the reliability of the supply chain system is built, the intuitionistic fuzzy set is introduced into the fuzzy Petri net model, and the model of supply chain reliability based on intuitionistic fuzzy Petri net is constructed by using intuitionistic fuzzy numbers. On the base of the change and the relationship between the kinds of fuzzy inference rules, the fuzzy inference rules of the supply chain reliability diagnosis model are divided into four types, which are obtained by the changes of the fuzzy inference rules with  prior or after trigger. At the same time, the fuzzy reasoning algorithm is put forward, and the validity of the model and the algorithm is verified by an example.

Key words: supply chain reliability, diagnosis model, intuitionistic fuzzy Petri net, fuzzy generative rules
