Models and algorithms for transit network planning por Ibarra Rojas, Omar Jorge

“…We design a mixed integer linear programming formulation (MILP) for SBT considering constraints such as bounds of separation times between consecutive trips and departure time dispersion along the planning period. We prove that SBT is NP-hard. Nevertheless, the mathematical structure of SBT MILP allow to define a preprocessing stage based on constraint propagation leading to the elimination of a high percentage of decision variables and constraints…”
