A Novel Vague Set Based Score Function for Multi-Criteria Fuzzy Decision Making
Author:
Abstract: For handling multi-criteria fuzzy decision-making problems, the degree of satisfiability and non-satisfiability of each alternative with respect to a set of criteria is often represented by a set of vague values. In multi-criteria fuzzy decision-making problems, vague set based score functions have become more and more popular for building models that concern the evaluation and comparison of alternatives in the decision-making process. However, several deficiencies remain evident when using these vague based score functions to handle multi-criteria decision-making problems. Therefore, the main objective of this study is propose a novel score function for a more effective and reasonable method for measuring the degree of suitability to which an alternative satisfied the decision maker’s requirement. An illustrative example is provided, which shows that the proposed vague set based score function is more effective and reasonable than other existing score functions in handling multi-criteria decision-making problems.
