Effect of Weightage of Jobs In Two Stage Flow Shop Scheduling To Minimize The Rental Cost With Jobs In A String Of Disjoint Job Blocks, Processing Time And Set Up Time Each Associated With Probabilities Including Breakdown Interval

This paper studies two stage flow shop production scheduling problem to minimize the rental cost under the specified rental policy with weightage of jobs. The processing time and set up time are associated with probabilities. The concept of breakdown interval of machines is also included and the jobs are taken in a string of disjoint job blocks. Further the jobs are given weightages. The objective of the study is to find an algorithm to minimize the rental cost of machines under the specified rental policy with breakdown interval and a string of disjoint job blocks. Algorithm is justified by numerical illustration.
