A Hybrid Genetic Algorithm for the Open Shop Scheduling with Makespan and Total Completion Time
Proper scheduling of tasks leads to optimum using of time and resources, in order to obtaining best result. One of the most important and complicated scheduling problems is open shop scheduling problem. There are n jobs in open shop scheduling problem which should be processed by m machines. Purpose of scheduling open shop problem is attaining to a suitable order of processing jobs by specified...

متن کاملA Two-Phase Constructive Heuristic for Permutation Flow-Shop Scheduling Problem Minimizing Total Completion Time
This paper describes a polynomial-time heuristic for the permutation flow-shop scheduling problem with the criterion of minimizing total completion time. The proposed method consists of two phases: arranging the jobs in priority order and then constructing a sequence. A new ranking method is employed to prioritize the jobs for incorporating into the construction phase of the heuristic. Computat...

متن کاملA New Branch-and-Bound for the Problem of Mean Completion Time for the Single Machine with Release Time
Preemptively scheduling a set of independent jobs with release time on one processor is a historical problem. In this paper, the same problem has been considered in which objective is to minimize the mean flow time. To prepare a perfect branch-and-bound, some optimality conditions have been represented and they have been compared with the optimality conditions which have been proposed before. O...
