2. EXPLOITING THE TIMETABLING FLEXIBILITY IN THE CONTEXT OF THE VEHICLE SCHEDULING PROBLEM WITH HETEROGENEOUS FLEET
ABSTRACT In the context of a heterogeneous fleet, the single-depot Vehicle Scheduling Problem is known as the Vehicle Type Scheduling Problem (VTSP). In this paper, we extend a VTSP model proposed in the literature to enable timetabling flexibility. Two strategies were developed to promote flexibility: aggregated trips and time windows. The former allows to

9. Development of a feasibility model for a High Speed Rail (HSR) line project
AbstractThe building costs of a High Speed Rail line project besides its acquisition, operation and maintenance ones, are very high making it an expensive option of transportation. The implementation of a HSR project must then be evaluated, determining its costs and revenues, in order to justify its viability. This research proposes a model to evaluate the f
