Scheduling is an enduring process where the existence of real time information frequently
forces the review and modification of pre-established schedules. The real world is complex and
complexity generally arises from uncertainty. From this prospective the concept of fuzziness is
introduced in the field of scheduling. The present paper pertains to a bi-criterion in n-jobs, three
machines flowshop scheduling to minimize the makespan and the rental cost of the machines taken on
rent under a specified rental policy in which processing time, transportation time are in fuzzy
environment and are represented by triangular fuzzy membership function. Further, the concept of job
block to represent the relative importance of some jobs over other is also introduced. A heuristic
algorithm to find optimal or near optimal sequence optimizing the bi-criteria is discussed. A
numerical illustration is given to demonstrate the computational efficiency of proposed algorithm. |
