In this paper, we consider the ranking problem of canonical intuitionistic fuzzy numbers. First, the concepts of canonical intuitionistic fuzzy numbers and fuzzy cut sets are defined, and the relation between generalized fuzzy numbers and canonical intuitionistic fuzzy numbers are studied. Next, the concept of Center index and Radius index of canonical intuitionistic fuzzy numbers which based on fuzzy cut sets are introduced, and the ranking index with the degree of optimism of decision maker for canonical intuitionistic fuzzy numbers is defined. Then a new ranking method based on ranking index is developed. Finally, to illustrate the validity of the proposed method, two numerical examples are presented, the results of the numerical examples show that the new method is reasonable and effective. |
