Timetable synchronization minimizes delays during such transfers. This paper formulates a novel measure for timetable synchronization by means of a total passenger dissatisfaction index (TPDI); and the impact of such synchronization on the original unsynchronized timetable is accounted using a total deviation index (TDV) that assigns penalties when deviations from the original timetable are incurred. Pareto fronts displaying the relationship between TPDI and TDV are generated using the state-of-the-art nondominated sorting genetic algorithm 2 (NSGA 2). To further improve NSGA 2, three schemes - the use of a variant of the NSGA2 with differential evolution, a process we termed "seeding," and finally a hybrid combination with local search techniques like heuristic hill climbing, tabu search, and simulated annealing - are proposed. Simulation results demonstrate that the "seeded" NSGA2-DE combined with the hill climbing heuristic produce the best results for the application. Solutions from the Pareto fronts are chosen for implementation to describe the different operating regions. A discussion section details the advantages and drawbacks of the proposed schemes. © 2008 IEEE.||Source Title:||IEEE Transactions on Systems, Man and Cybernetics Part C: Applications and Reviews||URI:||http://scholarbank.nus.edu.sg/handle/10635/83212||ISSN:||10946977||DOI:||10.1109/TSMCC.2008.923872|
