An Improved Elephant Herding Optimization for Energy-Saving Assembly Job Shop Scheduling Problem with Transportation Times

an assembly flow-shop scheduling problem with sequence-dependent setup and transportation times

in this paper, three-stage assembly flowshop scheduling is considered with respect to minimizing bi-objectives, namely mean flow time and mean tardiness. this problem is a model of production systems, which several production operations are done simultaneously and independently, and then produced components are collected and transferred to an assembly stage for the final operation. in this mode...

Section 1 introduces some { usual { notations about the general problem. Speciic notations concerning with setup times will be introduced later. The bibliograacal study, in Section 2 focuses on recent papers on both problems. Section 3 presents a general s...

A bi-objective model for the assembly flow shop scheduling problem with sequence dependent setup times and considering energy consumption

An Improved Tabu Search Algorithm for Job Shop Scheduling Problem Trough Hybrid Solution Representations

Job shop scheduling problem (JSP) is an attractive field for researchers and production managers since it is a famous problem in many industries and a complex problem for researchers. Due to NP-hardness property of this problem, many meta-heuristics are developed to solve it. Solution representation (solution seed) is an important element for any meta-heuristic algorithm. Therefore, many resear...

Hybrid algorithms for Job shop Scheduling Problem with Lot streaming and A Parallel Assembly Stage

In this paper, a Job shop scheduling problem with a parallel assembly stage and Lot Streaming (LS) is considered for the first time in both machining and assembly stages. Lot Streaming technique is a process of splitting jobs into smaller sub-jobs such that successive operations can be overlapped. Hence, to solve job shop scheduling problem with a parallel assembly stage and lot streaming, deci...
