A Study on Intuitionistic Fuzzy Critical Path Problems Through Centroid Based Ranking Method

In this study the intuitionistic fuzzy version of critical path method has been proposed to solve networking problems with uncertain activity durations. Intuitionistic set [1] is an extension theory [2] unlike set, it focuses on degree belonging, nonbelonging or non-membership function and hesitancy which helps decision maker adopt best among worst cases. Trapezoidal triangular numbers are utilized describe task durations project network. Here trapezoidal converted into their corresponding parametric form applying arithmetic operations a new ranking based numbers, vagueness reduced completion duration obtained. The authentication can be checked by comparing obtained results available in pieces literature.
