Two-Machine Flowshop Scheduling with Conditional
نویسندگان
چکیده
This paper considers a flowshop scheduling problem with a waiting time constraint imposed to restrict the processing of the two operations of each job. If the second operation of a job cannot start within a specified waiting time after the completion of its first operation, then an extra processing time will be incurred for its second operation as a penalty. We first show that is even a greatly restricted version of the problem is strongly NP-hard. We then develop an O(n) algorithm to determine the makespan of a processing sequence of the jobs.

MILP models and valid inequalities for the two-machine permutation flowshop scheduling problem with minimal time lags
In this paper, we consider the problem of scheduling on two-machine permutation flowshop with minimal time lags between consecutive operations of each job. The aim is to find a feasible schedule that minimizes the total tardiness. This problem is known to be NP-hard in the strong sense. We propose two mixed-integer linear programming (MILP) models and two types of valid inequalities which aim t...
متن کاملAppling Metaheuristic Algorithms on a Two Stage Hybrid Flowshop Scheduling Problem with Serial Batching (RESEARCH NOTE)
In this paper the problem of serial batch scheduling in a two-stage hybrid flow shop environment with minimizing Makesapn is investigated. In serial batching it is assumed that jobs in a batch are processed serially, and their completion time is defined to be equal to the finishing time of the last job in the batch. The analysis and implementation of the prohibited transference of jobs among th...
متن کاملParticle swarm optimization for minimizing total earliness/tardiness costs of two-stage assembly flowshop scheduling problem in a batched delivery system
This paper considers a two-stage assembly flow shop scheduling problem. When all parts of each product are completed in the first stage, they are assembled into a final product on an assembly machine in the second stage. In order to reduce the delivery cost, completed products can be held until completion of some other products to be delivered in a same batch. The proposed problem addresses sch...

متن کاملApproximability of two-machine no-wait flowshop scheduling with availability constraints
We consider in this paper the two-machine no-wait flowshop scheduling problem in which each machine may have an unavailable interval. We present a polynomial time approximation scheme for the problem when the unavailable interval is imposed on only one machine, or the unavailable intervals on the two machines overlap.
