Decision-making Method for Clay-brick Selection Based on Subtraction Operational Aggregation Operators of Intuitionistic Fuzzy Values

Abstract: The subtraction operation of intuitionistic fuzzy sets (IFSs) has been scarcely used for practical applications since it was introduced. Therefore, it is necessary to propose an aggregation operator based on the subtraction operation of IFSs for engineering applications. Then, clay-brick selection is an important decision-making problem for better building construction. To handle the decision-making problem based on the subtraction operation of IFSs in an intuitionistic fuzzy environment, this paper firstly introduces an intuitionistic fuzzy subtraction operational weighted arithmetic averaging (IFSOWAA) operator and investigates its properties. Then, we propose the IFSOWAA operator-based decision-making method as a supplement for existing decision-making methods under an intuitionistic fuzzy environment. Finally, an actual example about a clay-brick selection problem is provided to show the applicability and effectiveness of the proposed method.
