Abstract:The evaluation itself is characterized by randomness, ambiguity and uncertainty. In order to avoid the evaluation process being too subjective, a comprehensive evaluation method of Pythagorean fuzzy language based on combinatorial empowerment and cloud model is proposed. For the attribute value given by the expert is Pythagorean fuzzy language, the evaluation index is subjectively and objectively weighted according to G1 and CRITIC -G1(criteria importance though intercrieria correlation-order relation analysis )methods, and the combination weight is obtained by calculating the combination coefficient with the optimal weight by the game theory algorithm.Finally, the decision matrix of the Pythagorean fuzzy cloud mo-del is constructed for information gathering. Case analysis shows that this method optimizes decision-making in complex situations, and has feasibility and effectiveness.
