Combined effect of job and AGV dispatching rules on a flexible manufacturing system
… of the AGVS is governed by two kinds of AGV dispatching rules: Workcenter Initiated Rules (WI), and Vehicle Initiated Rules (VI). At work-centers. jobs are prioritized for processing by Job Dispatching (JD) Rules. The objective of the study is to characterize system behavior when dispatching …

The impact of vehicle dispatching on the design of multiple-transporters material handling systems
… of vehicles, the routes used by vehicles, the dispatching rules, and the guide path layout. There are two basic categories of AGVS control: static and dynamic. A static control system requires the automated guided vehicle (AGV) to run the same route continuously with stops at each …

A Mathematical Programming Based Procedure for the Scheduling of Lots in a Wafer Fab
… to the solution provided by the standard dispatching rules available in practice. In each experiment, the cycle time of a product for each dispatching rule is divided by the best cycle time for that product over all the dispatching rules in that experiment. This ratio for the Lagrangian …

Job shop scheduling to minimize work-in-process, earliness and tardiness costs
… neighborhood for better schedules iteratively. A dispatching rule selector based on neural network is developed to solve the performance fluctuation of dispatching rules. Computational results show that the proposed procedures significantly improve the schedule quality.

Air force crew allocation and scheduling problem
… to this situation, the heuristic scheduling and dispatching rules developed have been found to be very effective, and are generally applicable in other related contexts of routing, and crew and vehicle scheduling problems as well. The two algorithms developed have been applied to a coded set of …

Minimization of weighted tardiness in job shops using shifting bottleneck and tabu search procedures
… and their performance in comparison with dispatching rules. In particular, we find that the shifting bottleneck procedure outperforms tabu search for this problem.

Impact of Lot Dedication on the Performance of the Fab
… methodology consists of the development of a new dispatching rule for scheduling lots in the photolithography processing area. This along with the other dispatching rules discussed in the literature are implemented using the Autosched AP software to study the impact that lot dedication makes on …

A real-time simulation-based optimisation environment for industrial scheduling
… scheduling algorithm that combines priority dispatching rules and genetic encoding is proposed. This combination is demonstrated to be able to handle a wider range of problems or a current scheduling problem that may change over time, due to the flexibility requirements in the real-world. The …

Static and dynamic job-shop scheduling using rolling-horizon approaches and the Shifting Bottleneck Procedure
… approaches, namely mathematical programming and dispatching rules, have been explored in the literature so far, either partially or entirely dealing with this problem. Adapting the Shifting Bottleneck (SB) procedure is a third approach that has motivated many studies. Most research focuses on …
