Flexible Flow Shops

2012
We introduce four types of flexibility encountered in a flow shop: job routing through a hybrid shop, machine assignment, allocation of a scarce resource over the tasks to speed up processing, and the composition of daily production batches to satisfy requirements for a finite set of parts over a finite horizon.

A water-flow algorithm for flexible flow shop scheduling with intermediate buffers

Journal of Scheduling, 2010
We investigate the flexible flow shop scheduling problem with limited or unlimited intermediate buffers. A common objective of the problem is to find a production schedule that minimizes the completion time of jobs. Other objectives that we also consider are minimizing the total weighted flow time of jobs and minimizing the total weighted tardiness ...

A scheduling algorithm for flexible flow shop problem

Proceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527), 2003
This paper considers the flexible flow shops scheduling problem. The objective is to minimize the makespan. This is an NP-hard problem. A scheduling algorithm is presented. In this algorithm, the longest-processing-time-first heuristic is used for machine allocation. A genetic algorithm is used for solving the problem of finding a good loading sequence.

Pheromone based emergent shop floor control system for flexible flow shops

Artificial Intelligence in Engineering, 2001
New approaches for the development of shop floor control systems are needed to introduce better response to unanticipated disturbance situations and a better handling of ‘reconfiguration’ in production environments. In this paper, a development approach for agent-based shop floor control systems is presented, that uses co-ordination concepts as ...

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.
