Flow Shops and Flexible Flow Shops (Deterministic)

2008
In many manufacturing and assembly facilities each job has to undergo a series of operations. Often, these operations have to be done on all jobs in the same order implying that the jobs have to follow the same route. The machines are then assumed to be set up in series and the environment is referred to as a flow shop.

Performance Comparison of Some Classes of Flexible Flow Shops and Job Shops

International Journal of Flexible Manufacturing Systems, 1998
Flexible manufacturing systems (FMSs) for two-stage production may possess a variety of operating flexibilities in the form of tooling capabilities for the machines and alternative routings for each operation. In this paper, we compare the throughput performance of several flexible flow shop and job shop designs.

Uncertain flexible flow shop scheduling problem subject to breakdowns

Journal of Intelligent & Fuzzy Systems, 2016
Flexible flow shop scheduling problems become more complex when uncertain factors are taken into consideration. Most literature are under the assumption that machines are continuous available. But, a machine can be unavailable for many reasons, such as breakdown and planned preventive maintenance.

Approximation algorithms for two-stage flexible flow shop scheduling

Journal of Combinatorial Optimization, 2019
This paper deals with a two-stage flexible flow shop problem with a single machine at the first stage and \(m\) identical parallel machines at the second stage. The optimization criterion is the minimization of the makespan. First, a \((2 + \epsilon)\)-approximation algorithm is given.

Scheduling flexible flow shops with sequence-dependent setup effects

IEEE Transactions on Robotics and Automation, 2000
This paper presents a Lagrangian relaxation-based approach for production scheduling of flexible flow shops (PSFFS) where sequence-dependent setup effects are significant. PSPFS is first formulated as a separable integer programming problem with synchronization constraints between production and machine usage. Lagrangian relaxation is then applied, and

A heuristic Gupta-based flexible flow-shop scheduling algorithm

SMC 2000 Conference Proceedings. 2000 IEEE International Conference on Systems, Man and Cybernetics. 'Cybernetics Evolving to Systems, Humans, Organizations, and their Complex Interactions' (Cat. No.00CH37166), 2002
In simple flow-shop problems, each machine operation center includes just one machine. If at least one machine center includes more than one machine, the scheduling problem becomes a flexible flow-shop problem. Flexible flow-shops can thus be thought of as generalizations of simple flow-shops. C. Sriskandarajah and S.P.

Flow Shop Scheduling at Continuous Casters with Flexible Job Specifications

2011
We propose a new approach for the sequencing of slabs at continuous casters. Here, typical characteristics such as input supply in batch quantities, continuous casting width adjustment, width ranges for orders as well as setup times due to several process constraints are taken into account.

Study on No-Wait Flexible Flow Shop Scheduling with Multi-objective

2019
A multi-objective flexible flow shop scheduling model is constructed inclusive of production period, total expense, and mean flow time, which is based on the characteristics of dual-resource constrained no-wait flow shop scheduling problem with unrelated parallel machines.
