In this paper a hybrid genetic and harmony search algorithm is proposed to find the possible best sequence of operation solutions for hybrid flow shop scheduling problems. In this work the problem is considered with respect to the objective of minimization of makespan. Hybrid flow shop scheduling problem is considered for the sequencing of jobs in a hybrid flow shop with two or more identical m...

The problem of m-machine permutation flowshop scheduling is considered in this paper. The objective is to minimize the makespan. The flowshop scheduling problem is a typical combinatorial optimization problem and has been proved to be strongly NP-hard. Hence, several heuristics and meta-heuristics were addressed by the researchers. In this paper, a discrete African wild dog algorithm is applied...

We consider a real-life problem of scheduling clients orders in the production of concrete blocks in a factory of building industry. This problem can be modelled as a hybrid ̄ow shop scheduling problem with mixed no-wait/no-store constraints and mixed bottleneck/non-bottleneck machines. The objective function is to minimize maximum completion time. To solve the problem, we propose an approximat...

Hybrid Flowshop Scheduling (HFS) is one of the most comprehensively studied in scheduling problems. HFS has m-machines in each stage so that it is more complicated that regular flowshop scheduling. There are several production systems using HFS, such as steel manufacture, textile, and paper industry [8] [15]. Makespan and total tardiness are two important goals in scheduling to make the schedul...

In this paper the problem of serial batch scheduling in a two-stage hybrid flow shop environment with minimizing Makesapn is studied. 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 the mac...
