Minimizing Rental Cost for n-Jobs, 2-Machines Flow Shop Scheduling, Processing Time Associated with Probabilities Including Transportation Time and Job Block criteria
This paper deals with a heuristic algorithm to minimize the rental cost of the machines for two stage flow shop scheduling problem under specified rental policy in which processing times are associated with their respective probabilities. Further, the transportation time from one machine to another machine and an equivalent job block criteria is being considered. The purposed algorithm is easy to understand and provide an important tool for the decision makers. A computer program followed by a numerical illustration is also given to justify the algorithm. Keywords: Equivalent job, Flow Shop, Rental Policy, Transportation Time, Elapsed Time

On Linkage of a Flow Shop Scheduling Model Including Job Block Criteria with a Parallel Biserial Queue Network
This paper is an attempt to establish a linkage between a flowshop scheduling model having job block criteria with a parallel biserial queue network linked with a common channel in series. The arrival and service pattern both follows Poisson law in queue network. The generating function technique, law of calculus and statistical tools have been used to find out the various characteristics of queue. Further the completion time of jobs in a queue system form the set up time for the first machine in the scheduling model. A heuristic approach to find an optimal sequence of jobs with a job block criteria with minimum total flow time when the jobs are processed in a combined system with a queue network is discussed. The proposed method is easy to understand and also provide an important tool for the decision makers when the production is done in batches. A computer programme followed by a numerical illustration is given to justify the algorithm.
