An introduction to computer‐assisted train dispatch

Abstract

This paper provides a framework for assessing the progress that is being made in the computer-assisted dispatching of trains. The state of the art is described in general terms, and future research needs are identified.

A Fuzzy Petri Nets approach for railway traffic control in case of abnormality: Evidence from Taiwan railway system

“…Research has emphasized the developing analytical models in supporting managerial decisionmaking (Assad, 1980). Previous studies in the literature focused mostly on the adoption of simulation (Frank, 1965;Peat, Marwick, Mitchell, 1975;Petersen & Taylor, 1982), mathematical programming (Kraay et al, 1991;Petersen, Taylor, & Martland, 1986;Sauder & Westerman, 1983), and expert system (Komaya & Fukuda, 1991) for issues related to railway traffic control. Sahin (1999) adopted a utility function of some weighted attributes for each conflict to determine dynamic train priority according to the calculated values of the dynamic priorities of trains.…”

Optimizing Train Network Routing Using Deterministic Search

“…Later, Carey and Lockwood developed a basic model to serve as the foundation for further research (Carey and Lockwood 1995). Other authors developed the computer-aided dispatch systems (Petersen et al 1986;Jovanovic and Harker 1991). In order to solve some complex problems, researchers have devised various algorithms for optimizing the train routing, such as the heuristic method based on Lagrangian relaxation (Keaton 1989), the combination of genetic and tabu search algorithms (Gorman 1998a), expert system (Lozano et al 2002 and neural network (Martinelli and Teng 1996).…”

Timetabling optimization of a single railway track line with sensitivity analysis

“…Though train timetabling was done manually for more than a century, nowadays it cannot be conceived without the help of a computer (Petersen et al 1986). An excellent review of analytical models developed before the eighties for rail transportation is provided by Assad (1980).…”
