Reactive fuzzy dispatching rule for automated guided vehicles
SMC'03 Conference Proceedings. 2003 IEEE International Conference on Systems, Man and Cybernetics. Conference Theme - System Security and Assurance (Cat. No.03CH37483), 2004The automated manufacturing system (AMS) scheduling complexity increases with products customization, due dates, alternative routes and no foresee demand in the system. One of the important aspects in shop floor is to ensure that the parts will be at the right position and at the defined time.

A survey of dispatching rules for the dynamic unrelated machines environment
Expert Systems with Applications, 2018In the real world, scheduling is usually performed under dynamic conditions, which means that it is not known when new jobs will be released into the system. Therefore, the procedure which is used to create the schedule must be able to adapt to the changing conditions during the execution of the system.

Switching Dispatching Rules with Gaussian Processes
2012Decentralized 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.

Dispatching rules for dynamic scheduling of one-of-a-kind production
International Journal of Computer Integrated Manufacturing, 2006This paper presents an extensive performance analysis of dispatching rules for dynamic scheduling in one-of-a-kind production (OKP) where each job has its own due-date and multilevel routing structure. For the analysis, a framework of dynamic dispatching rules is proposed to identify five dispatching rules: job due-date (JDD) rule, normalized JDD rule,

Adaptive Dispatching Rule for Semiconductor Wafer Fabrication Facility
IEEE Transactions on Automation Science and Engineering, 2013Uncertainty in semiconductor fabrication facilities (fabs) requires scheduling methods to attain quick real-time responses. They should be well tuned to track the changes of a production environment to obtain better operational performance. This paper presents an adaptive dispatching rule (ADR) whose parameters are determined dynamically by real-time ...

Evolutionary Learning of Linear Composite Dispatching Rules for Scheduling
2015A prevalent approach to solving job shop scheduling problems is to combine several relatively simple dispatching rules such that they may benefit each other for a given problem space. Generally, this is done in an ad-hoc fashion, requiring expert knowledge from heuristics designers, or extensive exploration of suitable combinations of heuristics.

Comparing dispatching rules in dynamic hybrid flow shops
2006 IEEE Conference on Emerging Technologies and Factory Automation, 2006In this paper, several dispatching rules are studied in hybrid flow shop environment using simulation in order to minimize the mean flow time as well as standard deviation. Hybrid flow shops are productive systems with several stages. Every stage is composed of a pool of machines. This kind of productive configuration has been largely studied in recent

Optimizing Dispatching Rules for Stochastic Job Shop Scheduling
2019Manufacturing environments commonly present uncertainties and unexpected schedule disruptions. The literature has shown that in these environments simple and fast dynamic dispatching rules are efficient sequencing methods. However, most of the works in the automated designing of these rules have considered deterministic processing times. This work aims

Multiresponse optimization of dispatch rules for public bus services
Computers & Industrial Engineering, 2009A multiple response optimization approach based on an integrated simulation model and a service reliability measure is proposed for optimizing the dispatch rules of public bus services. The simulation model is based on two novel Markov models for modeling passenger loads and headway fluctuations.
