Research on TOPSIS Multi-attribute Group Decision-making Based on Interval Python Fuzzy WA Operator
Aiming at the mixed multi-attribute group decision-making problem of interval Pythagorean fuzzy,a WA operator model based on interval Pythagorean fuzzy set is constructed,and a decision-mak-ing method based on interval Pythagorean fuzzy TOPSIS is proposed.Firstly,based on the complete un-known weights of decision makers and attributes,interval Pythagorean fuzzy is applied to TOPSIS group decision-making;Secondly,the interval Pythagorean fuzzy number WA operator is used to synthesize the evaluation matrices of multiple decision makers into a comprehensive evaluation matrix,and the rel-ative closeness of each scheme is calculated based on TOPSIS decision-making method;Finally,the ra-tionality and effectiveness of the method proposed in this paper were verified through the analysis of coupled innovation examples between industry and universities.
