However, in the context of Industry 4.0, there is a lack of studies related to the scheduling and rescheduling process integrating industries on the operational level. This paper proposes a novel hybrid flow shop rescheduling procedure to address the integration, on the operational level, of a ...
The manufacture model of tube product line in shipyard can be considered as Hybrid Flow Shop. 造船企业管子加工生产的生产模式可以归结为一种混合流水生产线。 www.ceps.com.tw 2. The first algorithm allocates jobs to machines and converts the hybrid flow-shop problem in to several flow-shop prob...
The hybrid flow-shop scheduling problem with multiprocessor tasks finds its applications in real-time machine-vision systems among others. Motivated by this application and the computational complexity of the problem, we propose a genetic algorithm in this paper. We first describe the implementation det...
In this paper, we consider a two-stage hybrid flowshop in a group technology environment. We assume that parts are grouped into families and a major setup is required when a machine at either stage starts to process a new family. While Stage 1 contains a single machine, Stage 2 contains ...
In this paper we consider a two-stage hybrid flowshop scheduling problem, where each of n tasks is to be processed first at stage one and then at stage two. The first stage contains several identical discrete machines and the second stage contains several identical batching machines. Each discr...
They are extensions of classical flow shop scheduling problems in which a set of jobs need to be processed in a group of machines following the same route. In a HFS problem, there are a series of production stages in place of machines, and each stage consists of several parallel machines....

These tasks have to belong to jobs of the same group. 3. Related Works 3.1. Energy-Aware Flow Shop Scheduling Investment in new equipment and hardware can certainly contribute to energy savings [9]. The use of “soft” techniques to achieve the same objective is also an effective option [...

If the required setup time to prepare each machine to process a group is dependent on the previous processed group on that machine, the problem is called a Flow Shop Sequence Dependent Group Scheduling (FSDGS) problem. Schaller et al. [2] investigated the FSDGS problems for the first time....
