A multi-criteria decision making problem based on score function of bipolar intuitionistic fuzzy soft set

Abstract

In this paper, a score function using weighted geometric aggregation operator (WGAO) based on bipo- lar intuitionistic fuzzy soft set (BIFSS) is defined. The score function and WGAO involving the hesitancy part are proposed. A methodology to solve the multi-criteria decision making problem (MCDM) in BIFSS environment is framed. Further, an illustration is given to explain the application of this method.In this paper, a score function using weighted geometric aggregation operator (WGAO) based on bipo- lar intuitionistic fuzzy soft set (BIFSS) is defined.
