Abstract
A case study of translation of theoretical developments (Friedman, 1975; 1976) to implementation procedures is outlined with specific reference to the Rio de Janeiro Subway System. Within the overall framework of establishing the time schedule of trips of a single line that minimizes the average waiting time of passengers with possible generalization and extension to multi-line network, the present manuscript has the limited aim of developing a time table and determining the minimal number of trains required to keep up a given schedule of trips of a single line. The incorporation of a new ad-hoc procedure of “inclusion and exclusion trips” to and from an intermediate regulating station is a novel feature not included in the original Friedman Model. This supplement characterizes an important physical attribute of the Rio de Janeiro System, namely, the limited train storage capacity at the terminal stations which is offset by virtual unlimited storage capacity at the intermediate regulating station. The case study has generated a procedure for creation and manipulation of large data bases in real life applications encountering practical constraints using a theoretically sound set of efficient algorithms.
