| Summary | In the past, research scholars usually used deterministic passenger demands as input for inter-city bus scheduling, simplifying the stochastic disturbances of daily passenger demands in actual operations. In addition, inter-city bus carriers in practice may aim at maximizing both the operating profit and the market share in their short-term operations, instead of confining to a single objective which was usually adopted in the inter-city bus scheduling literature. Considering the multiple objective and stochastic demands in actual operations, we employed network flow techniques to construct a stochastic-demand multi-objective scheduling model, with the objectives of maximizing the operating profit and the number of passengers, to help inter-city bus carriers effectively plan their bus fleet routes and timetables in their short-term operations. The model is formulated as a multiple objective nonlinear mixed integer program. We used the weighting method and the simulation technique to develop a heuristic algorithm to solve the model. To compare the performance of the deterministic-demand and stochastic-demand scheduling models in actual operations, we developed a simulation-based evaluation method. Finally, we conducted a case study using real operating data from a major Taiwan inter-city bus carrier. The results indicated that the model and the solution algorithm could be useful for inter-city bus carriers. |
