Efficient jobshop dispatching rules: Further developments

Production Planning & Control, 2000
Many dispatching rules for scheduling in dynamic jobshops have been proposed over many years. The research issues in jobshop scheduling seem to be still open in the sense that no single rule has been found to be the best under all shopfloor conditions even with respect to one single measure of performance.

Characterization of automatic guided vehicle dispatching rules

International Journal of Production Research, 1984
SUMMARY Hardware failures notwithstanding, the ability of an automated system operating according to promised potential is dependent upon the operational control measures in force. In this paper, some heuristic rules for dispatching Automatic Guided Vehicles (AGVs) in a job shop environment are presented.

Switching Dispatching Rules with Gaussian Processes

2012
Decentralized scheduling with dispatching rules is applied in many fields of production and logistics, especially in highly complex manufacturing systems, e.g. semiconductor manufacturing. Nevertheless, no dispatching rule outperforms other rules across various objectives, scenarios and system conditions.

Robust scaling parameters for composite dispatching rules

IIE Transactions, 2010
The successful implementation of composite dispatching rules depends on the values of their scaling parameters. A unified four-phase method to determine robust scaling parameters for composite dispatching rules is proposed, with the goal of achieving reasonably good scheduling performance with the least computational effort in implementation.

Data envelopment analysis for dispatching rule selection

Production Planning & Control, 1999
Scheduling techniques and dispatching rules are widely studied because of their strategic role in achieving optimal management of manufacturing systems. In the case of flexible manufacturing, it is essential to evaluate the effects of different dispatching rules to foresee the overall system performance.

Creating dispatching rules by simple ensemble combination

Journal of Heuristics, 2019
Dispatching rules are often the method of choice for solving scheduling problems since they are fast, simple, and adaptive approaches. In recent years genetic programming has increasingly been used to automatically create dispatching rules for various scheduling problems.

Piloting of AGV systems with dispatching rules

1996 IEEE International Conference on Systems, Man and Cybernetics. Information Intelligence and Systems (Cat. No.96CH35929), 2002
Automated guided vehicles (AGVs) are a highly sophisticated and increasingly popular type of material handling device in flexible manufacturing systems (FMS). The research is based on the result of a previous study presented in Albert and Castagna (1996). There, the study consists of the description of a conflict management method.

Ontology and semantic rules in document dispatching

The Electronic Library, 2009
PurposeThe purpose of this paper is to demonstrate how the semantic rules in conjunction with ontology can be applied for inferring new facts to dispatch news into corresponding departments.Design/methodology/approachUnder a specific task domain, the proposed design comprises finding a glossary from electronic resources, gathering organization ...

Dispatching Rules for Manufacturing Job-Shop Operations

IFAC Proceedings Volumes, 1993
Abstract This paper presents comparative results on dispatching rules in job shop scheduling under various shop load ratio and various due date tightness conditions. Analysis of variance is used. Although it is impossible to identify any single rule as the best in all circumstances, P+S/OPN and MPS rule has been identified as exhibiting good ...
