Site Selection of Solar Plant based on Normal Wiggly Hesitant Bipolar-Valued Fuzzy Set

Abstract

Hesitant fuzzy set is a popular and powerful tool to express multiple values in decision making. If they are unable to provide a resolution, it is important to prioritize and prioritize different values. In this study, we explore the potential/deep uncertainties of decision makers(DMs) when using HBFSs to disclose their rating information in the decision-making process. Here, we propose theNormal wiggly Hesitant Bipolar Fuzzy set (NWHBFS) as an extension of the normal wiggly hesitant fuzzy set. The NWHBFS can express deep opinions about positive and negative membership information. NWHFSs can hold hesitant fuzzy information and deeply uncertain information into hesitant fuzzy information. After that, we propose the normal wiggly hesitant bipolar fuzzy information scoring function to differentiate NWHBFS. Furthermore, in order to understand and apply NWHBFS, we explore some of the characteristics of NWHBFs and propose NWHBFS preliminary aggregation operators. Finally, we use a numerical example.
