| Abstract: | In solving the problem that the attribute value is intuitionistic fuzzy number of multiple attribute decision, its weights are unknown information. Solving the weights with entropy value method, and using intuitionistic trapezoidal fuzzy number weighted average operator to calculate every index value of the average, the score function and the expected functions based on intuitionistic trapezoidal fuzzy number are given, and the method and steps to solve the problem are offered. According to the score function value to rank, the optimal solution is selected. Finally an example is used to illustrate the effectiveness of this method. |
