Study of Sequencing Problem using different ranking techniques in Fuzzy Environment

Abstract

In this paper, comparison between Yager's ranking and Robust ranking is done on job sequencing problems, in which processing times are taken as trapezoidal fuzzy number. Firstly sequencing problem is solved by using proposed algorithm and then Yager's ranking and robust ranking is applied for the defuzzification of fuzzy job sequencing problems. With the help of numerical example it is shown that Yager's ranking is more effective for handling fuzzy sequencing problem than robust ranking.
