The present work aims to give a solution for a scheduling problem in a flexible flow-shop with non-identical parallel machines and sequence-dependent set-up times, where the objective function is to minimize the number of tardy jobs. This production setting has not been deeply studied in the ...
flow shopmachine availabilitymixed integer programming (MIPSummary This chapter deals with mixed integer programming (MIP) models for scheduling of flow shops, the design in which dedicated machines are arranged in series or in series and parallel, and in which a transportation system imposes a ...
The classical flexible flow shop scheduling problem (FFSP) only considers machine flexibility. Thus far, the relevant literature has not studied FFSPs with worker flexibility, which is widely seen in practical manufacturing systems. Worker flexibility may greatly affect production efficiency and ...
If at least one machine center includes more than one machine, the scheduling problem becomes a flexible flow-shop problem. Flexible flow shops are thus generalization of simple flow shops. In this paper, we propose three algorithms to solve flexible flow-shop problems of more than two machine ...
Although various approaches have been developed for scheduling under uncertainty, this problem is still difficult to tackle by any single approach, because of its inherent difficulties. This paper considers makespan minimisation of a flexible flow shop (FFS) scheduling problem with stochastic processing ...
In this research, flexible flow shop scheduling with unrelated parallel machines at each stage are considered. The number of stages and machines vary at each stage and each machine can process specific operations. In other words, machines have eligibility and parts have different release times. In...
这个领域最困难的问题之一是作业车间调度问题(Job-shop Scheduling Problem, JSP),该问题中,一组机器需处理一组工件,每个工件由一系列具有先后顺序约束的工序形成,每个工序只需要一台机器,机器一直可用,可以一次处理一个操作而不会中断。决策内容包括如何对机器上的工序进行排序,已优化给定的性能指标。JSP的典型性能指标...
A flow shop system with such flexible properties; i.e., FFSSP, or sometimes called Hybrid Flow Shop Scheduling Problem (HFSSP) (Jayamohan & Rajendran, 2000). The effectiveness of the FFSSP in some manufacturing sectors, e.g., steel production (Long et al., 2018), and electronics ...
