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 ...

Priority dispatching rules in an assembly shop

Omega, 1987
Abstract This paper reports the results of a job shop computer simulation study in which jobs were made up of several parts, and where operations on the different parts can be going on at the same time in different machining centres. Priority rules are evaluated in terms of average job flow time, and have been chosen mainly for their ability to ...

On-line dispatching rules for vehicle-based internal transport systems

International Journal of Production Research, 2005
On-line vehicle dispatching rules are widely used in many facilities such as warehouses and manufacturing facilities to control vehicles' movements. Single-attribute dispatching rules, which dispatch vehicles based on only one parameter, are usually used. However, multi-attribute dispatching rules prove to be better in general.

Dispatching rules for stochastic finite capacity scheduling

Computers & Industrial Engineering, 1998
In his paper, we investigate how dispatching rules affect the performance of stochastic simulation-based finite capacity scheduling systems and provide guidance for schedulers to determine effective dispatching rules for stochastic simulation-based finite capacity scheduling systems.

Emergency Medical Service Response: Analyzing Vehicle Dispatching Rules

Transportation Research Record: Journal of the Transportation Research Board, 2018
In an era of information and advanced computing power, emergency medical services (EMS) still rely on rudimentary vehicle dispatching and reallocation rules. In many countries, road conditions such as traffic or road blocks, exact vehicle positions, and demand prediction are valuable information that is not considered when locating and dispatching ...

Generating interpretable fuzzy rules for adaptive job dispatching

International Journal of Production Research, 2001
Adaptive scheduling is an approach that selects and applies the most suitable strategy considering the current state of the system. The performance of an adaptive scheduling system relies on the effectiveness of the mapping knowledge between system states and the best rules in the states.

Dynamic selection of dispatching rules by fuzzy inference

1998 IEEE International Conference on Fuzzy Systems Proceedings. IEEE World Congress on Computational Intelligence (Cat. No.98CH36228), 2002
Proposes a fuzzy inference-based selection of dispatching rules, adapting the scheduling decision to the dynamic changes in the manufacturing environment. In the proposed method, the performance of different dispatching rules is studied while varying production conditions.

Selection of dispatching rules with fuzzy ANP approach

The International Journal of Advanced Manufacturing Technology, 2010
Nowadays, the requirement of flexibility in manufacturing has been increased rapidly because of severe market competition in which customer demand should be met in a right time and in a right way. Although there can be many reasons which affect productivity of the flexible manufacturing system (FMS), one of the crucial one is a scheduling policy which ...
