Abstract :

In this paper, TOPSIS Ranking method has been utilized to find the critical path for the project scheduling problem with the aid of more generalized Interval valued fuzzy numbers (MIVFNS). The
properties of single weighted and double weighted fuzzy numbers have been studied. New algebraic arithmetic’s of these GIVFNS are utilized and investigated. A relevant Numerical illustration is also included to explain the method.

Keywords :
