Research on the Improvement of TODIM Decision Method Based on Triangular Intuitionistic Fuzzy Information

Abstract

The core of management is decision making. Scientific and efficient decision making on complex problems is the key to modern enterprise management. The decision-making oriented complex problems is characterized by multi-attribute, fuzzy evaluation information, group decision - making and influenced by decision-maker's behavior. In order to meet the needs of complex problem decision making, the classical TODIM method is limited to deal with precise number, traditional fuzzy number and intuitionistic fuzzy number, etc., so it cannot well deal with the decision-maker's hesitation and the discretization of intuitionistic fuzzy number domain at the same time. In this paper, the triangular intuitionistic fuzzy number was extended to the TODIM method, and the triangular intuitionistic modulus mixed average and mixed geometric integration operator were proposed to realize the fuzzy information expression and decision calculation method that accords with the psychological behavior characteristics of decision-makers. This method can be applied to multi-attribute and group decision making in modern enterprise management with known attribute and decision-maker weight.
