Z-soft rough fuzzy graphs: A new approach to decision making

摘要

The aim of this paper is to discuss the uncertainty in soft graphs and a new type of graphs, called Z-soft rough fuzzy graphs is introduced. The notions of Z-soft rough vertex graphs, Z-soft rough edge graphs and Z-soft rough fuzzy graphs are given, and their related properties are explored. The theory of graph approximation space is developed. To validate the applicability of Z-soft rough fuzzy graphs, we put forward an innovative approach to multicriteria group decision making problems.
