Similarity measures of intuitionistic fuzzy soft sets and their decision making

Abstract: In this article, we define some types of distances between two intuitionistic fuzzy soft (IFS) sets and proposed similarity measures of two IFS-sets. We then construct a decision method which is applied to a medical diagnosis problem that is based on similarity measures of IFS-sets. Finally we give two simple example to show the possibility of using this method for diagnosis of diseases which could be improved by incorporating clinical results and other competing diagnosis.
