Intuitionistic fuzzy technique to find the critical path

Abstract

In this paper, intuitionistic fuzzy number has been applied to find the critical path for the project scheduling problems with the aid of interval valid intuitionistic fuzzy numbers (IVIFN). Decision maker’s risk attitude index and decision maker’s risk index ranking value has also been utilized to find the critical path. In order to explain intuitionistic fuzzy technique to find critical path, numerical example has been illustrated in this paper.
