Abstract

This paper use the intuitionistic fuzzy value and intuitionistic fuzzy sets, based on the method of TOPSIS to select and determine the similarity function for intuitionistic fuzzy sets, and use the information entropy to calculate the weight, then use the distances from intuitionistic fuzzy sets to intuitionistic fuzzy positive ideal point (PIS) and negative ideal point (NIS), weighted and composted, finally, got the relative closeness for that need to evaluation program with the ideal point. The relative closeness is the coordination degree of enterprise node of supply chain.
