Robust's Ranking Function for Generalized 4th Multiple Polygonal Fuzzy Number

Jitendra Singh, Deepak Kumar

Abstract: We generalized an arithmetic operation of 4th multiple polygonal fuzzy numbers with its membership function. In this paper, we suggested Robust's ranking function for 4th multiple polygonal fuzzy numbers by using alpha-cut. The complexity in solving this type of problems has reduced to easy computation.
