Idle / Waiting Time Operator Oi,w Of An Equivalent Job For A Job Block Criteria To Minimize The Rental Cost In Two Stage Flow Shop Scheduling, the Processing Time Associated With Probabilities

The present paper is an attempt to study the n x 2 flow shop production scheduling problem in which the processing times are associated with their respective probabilities and follows some restrictive rental policy including equivalent job block criteria. The objective of the study is to get optimal sequence of the jobs in order to minimize the rental cost using idle/waiting time operator through the iterative algorithm. The operator technique is an easy approach in economical and computational point of view and gives an optimal schedule rule in order to minimize the rental cost of the machines. The model is justified by a computer programme followed by a numerical illustration
