This paper consists of afuzzy flow shop scheduling problem whose objective is to minimize the total elapsed timeof jobs involvingjob block. The processing time setup time and transportation time are taken as triangular fuzzy numbers which are defuzzified into crisp ones by Yager's method. The optimal sequence is found by Johnson's algorithm and the minimum totalelapsed time is found. The approach is illustrated by a numerical example.
Transportation time, Job blocks, Optimal sequence, Total elapsed time
