The challenge of increasing train velocities, highly interdependent schedules and higher traveller demands force train traffic providers to improve the punctuality and reliability of their train services. The dispatchers, which try to reduce the effects of unavoidable disturbances and to keep the trains close to the schedule, are overcharged by their tasks and need to be supported by advanced s...

Dispatching rules are frequently used to schedule jobs in flexible manufacturing systems (FMSs) dynamically. A drawback, however, to using dispatching rules is that their performance is dependent on the state of the system, but no single rule exists that is superior to all the others for all the possible states the system might be in. This drawback would be eliminated if the best rule for each ...

Items arrive at a processing plant at a Folsson rate X . At time T , all Items are dispatched from the system. An Intermediate dispatch time Is to be chosen to minimize the total wait of all Items. It Is shown that If the dispatch time must be chosen at time 0 then T/2 not only minimizes the expected total wait but it also maximizes the probability that the total wait is less than a for every a...

The aim is to develop a robust methodology for dispatching and routing of emergency vehicles (EVs) in a post-disaster environment with the support of data fusion for decision-making. In this work we consider an earthquake scenario with a large number of casualties needing medical attention. With the influx of information (about the casualties, road and traffic conditions, etc.) data is fused to...

In this paper we present conflict resolution measures in connection dispatching suitable for railway transportation companies without having full access to relevant data. The presented measures do not only cover classical waiting/non-waiting-strategies but also alternative dispatching measures if a distributor train cannot wait. The fact of unknown travel chains and insufficient data availabili...

Modern mobile dispatching system can provide real-time monitoring and dispatching of moving vehicles via the support of different enabling technologies, such as, mobile communications, Global Positioning System (GPS), Geographical Information System (GIS), and embedded real-time system design. In this article, we present the design of a Modular Mobile Dispatching System (MMDS) for the distribut...

A promising approach for an effective shop scheduling that synergizes the benefits of the combinatorial optimization, supervised learning and discrete-event simulation is presented. Though dispatching rules are in widely used by shop scheduling practitioners, only ordinary performance rules are known; hence, dynamic generation of dispatching rules is desired to make them more effective in chang...
