Fleet Size and Frequency in Rapid Transit Systems

Given is a set of stations linked by railway tracks, forming an undirected railway network. one or more lines are formed in this network. each line consists of an origin station, a destination station, and a number of intermediate stations. in order to complete the line configuration, it is needed to decide the frequency (number of services per hour) and the capacity (number of carriages) for each train. this problem is called the line frequency and capacity setting. in this work, an il based algorithm for solving this problem when the objective function is the net profit, is proposed. a version of this problem that takes into account the passenger behavior is also considered. finally, some computational results are presented.
