Application of intuitionistic fuzzy critical path method on airfreight ground operation systems

Abstract

The main objective of this paper is to express how intuitionistic fuzzy critical path method helps and 11 improves the working process of the airfreight ground operation system. In this way, an example is discussed based 12 on the application of intuitionistic fuzzy critical path method for airfreight ground operation systems. Instead of 13 following the traditional method to find critical path and total completion duration of intuitionistic fuzzy critical 14 path analysis, we have proposed a new approach that is easier and simple to understand when compared with 15 existing methods. Here activity durations are represented as trapezoidal intuitionistic fuzzy numbers. Also, a 16 new centroid based ranking grade of modal value, left fuzziness and right fuzziness index of membership and 17 nonmembership functions of trapezoidal intuitionistic fuzzy numbers has been applied.
