Abstract:

Some operation laws of triangular and interval-valued fuzzy sets were defined. Two amelioration operators were developed, such as the triangular intuitionistic fuzzy numbers weighted arithmetic average (FIFWAA) operator, and the f interval-valued intuitionistic fuzzy numbers weighted geometric average (FIFWGA) operator. On this basis, the problem that score function can not give decision-making was solved by accuracy function in order to ensure the security and rationality of score function. An approach for solving uncertain multiple attribute decision-making problem was given, in which the attribute weights were not completely certain and the attribute values were triangular and interval-valued fuzzy numbers. An illustrative example proves the effectiveness and correctness of multiple-criteria decision-making with intuitionistic fuzzy sets.
