Approach to multiple attribute decision making with hesitant triangular fuzzy information and their application to customer credit risk assessment

Abstract

We investigate the multiple attribute decision making (MADM) problems with hesitant triangular fuzzy information. Firstly, some operational laws of hesitant triangular fuzzy elements and score function of hesitant fuzzy elements are introduced. Then, we have developed the hesitant triangular fuzzy choquet ordered geometric (HTFCOG) operator. The prominent charac- teristic of the operators is that they can not only consider the importance of the elements or their ordered positions, but also reflect the correlation among the elements or their ordered positions. We have applied the HTFCOG operators to multiple attribute decision making for evaluating the customer credit risk of commercial bank with hesitant triangular fuzzy information. Finally an illustrative example for evaluating the customer credit risk of commercial bank has been given to show the developed method.
