Due to the limitation of sensing ability,the fuzzy membership of the remote AUV autonomous decision-making attribute is not clear,thus the traditional fuzzy Petri net decision-making method can not implement knowledge representation and reasoning.This paper expands the fuzzy set of fuzzy Petri nets,puts forward the concept of interval-valued intuitionistic fuzzy Petri net,and redesigns the reasoning methods and decision-making process.Based on the interval-valued intuitionistic fuzzy Petri net,the remote AUV action decision-making model is established,and the remote AUV autonomous action decision-making is realized by using an example.The decision-making process is eloquent,rapid and clear,and the result of the decision-making proves the validity of the method.This method gives a new thought to multi-attribute decision-making.
