On Minimizing Machines Rental Cost Using Heptagonal Fuzzy Processing Time

Abstract

This paper is concerned with minimizing the total rental cost of special structure three phases flow shop scheduling problem. We propose a new approach to solve such problem with heptagonal fuzzy processing time. The heptagonal fuzzy processing time is processed without transforming it to a deterministic number. For demonstrating the efficiency of the proposed approach, a numerical example is illustrated.
