Analyzing a few Heuristic Algorithms Considering Machine Idle Time and Processing Time in Permutation Flow Shop Scheduling Problems

A Mathematical Programming Model for Flow Shop Scheduling Problems for Considering Just in Time Production

  In this paper, we consider a flow shop scheduling problem with bypass consideration for minimizing the sum of earliness and tardiness costs. We propose a new mathematical modeling to formulate this problem. There are several constraints which are involved in our modeling such as the due date of jobs, the job ready times, the earliness and the tardiness cost of jobs, and so on. We apply adapte...

Modeling and scheduling no-idle hybrid flow shop problems

Although several papers have studied no-idle scheduling problems, they all focus on flow shops, assuming one processor at each working stage. But, companies commonly extend to hybrid flow shops by duplicating machines in parallel in stages. This paper considers the problem of scheduling no-idle hybrid flow shops. A mixed integer linear programming model is first developed to mathematically form...

A new Nawaz–Enscore–Ham-based heuristic for permutation flow- shop problem with bicriteria of makespan and machine idle-time

Efficient Algorithms for Just-In-Time Scheduling on a Batch Processing Machine

Just-in-time scheduling problem on a single batch processing machine is investigated in this research. Batch processing machines can process more than one job simultaneously and are widely used in semi-conductor industries. Due to the requirements of just-in-time strategy, minimization of total earliness and tardiness penalties is considered as the criterion. It is an acceptable criterion for b...
