This paper is an attempt to obtain an optimal solution for optimizing the bicriteria taken as minimization of the total rental cost of the machines taken on rent under a specified rental policy subject to obtain the minimum makespan for n-jobs, 2-machine flowshop scheduling problem. The processing time of jobs are uncertain in nature that is not known exactly and are in fuzzy environment. The fuzzy processing times are described by triangular fuzzy membership function. Further the concept of job blockage in processing of jobs is introduced. A numerical example is provided to demonstrate the computational efficiency of proposed algorithm.
