Intuitionistic Fuzzy Multi-attribute Decision Making Method Based on Combination Weight Method

In the context of intuitionistic fuzzy information, for the multi-attribute decision-making problem with incompletely determined attribute weights, this paper proposes a new dynamic decision-making method based on combination weighting. First, the analytic hierarchy process and the deviation maximization method are used to determine the subjective and objective dynamic combination weights of attributes, which overcomes the shortcomings of single weighting. Then, based on this weighting method, an intuitionistic fuzzy multi-attribute dynamic decision-making model is established. Finally, a numerical example is used to illustrate the effectiveness and practicability of the method.
