Railroad network model

Handbook of Operations Research Applications at Railroads

“…Under this approach, stochastic elements are introduced to reflect variations in train operations, variations in yard operations, and potentially even events like periodic bad ordering of cars. The authors are not aware of any successful examples of such simulations at a network level, though some attempts have been made to create them (Allman 1966a, b;Bellman 1967;Wilson and Hudson 1970;Petersen and Fullerton 1975).…”

“…Regarding simulation models, we refer the interested reader to the works by Allman (1966Allman ( a, b, 1967, Bellman (1967), Wilson and Hudson (1970), and more detailed reviews of network simulation models by Assad (1980b), and Bongaardt et al (1980) who summarize practical applications of some of the network simulation models. Table 3 summarizes some of the most important contributions to the two classes of models which were reviewed in this section.…”
