This paper aims to study the locomotive routing problem (LRP) which is one of the most important problems in railroad scheduling in view of involving expensive assets and high cost of operating locomotives. This problem is assigning a fleet of locomotives to a network of trains to provide sufficient power to pull them from their origins to destinations by satisfying a rich set of operational con...

The paper proposes a multi-agent method to creating an intelligent adaptive system of train real time scheduling with conflict limitations. The architecture of the multi-agent system consisting of two base planning subsystems is described. Subsystem interaction protocols and protocols of agent interaction within each subsystem are presented. The example of schedule planning in various situation...

Scheduling of trains on a single line involves the use of train priorities for the resolution of conflicts. First, a mathematical programming model is described. The model schedules trains over a single line of track when the priority of each train in a conflict depends on an estimate of the remaining crossing and overtaking delay. This priority is used in a branch-and-bound procedure to allow ...

A train scheduling problem in a single-track railway is studied using a mixed graph model for a job-shop with appropriate criteria. There are several performance evaluations for a train schedule. Optimizing a train schedule subtends minimizing total tardiness of the trains, minimizing the sum of train transit times, minimizing the makespan for a train schedule, etc. Since the corresponding job-...

Scheduling of trains on a single line involves using train priorities for the resolution of conflicts. The mathematical programming model described in the first part of this paper schedules trains over a single line track when the priority of each train in a conflict depends on an estimate of the remaining crossing and overtaking delay. This priority is used in a branch and bound procedure to a...

In diesem Beitrag wird ein SystemC-Modell der Geschwindigkeitsund Abstandsüberwachung aus dem European Train Control System (ETCS) vorgestellt. Dieses Modell dient als Ausgangspunkt für die frühzeitige Abschätzung der Leistungsfähigkeit des Systems und die in der Berechnung entstehenden Datenmengen. Hierfür wurde eine neuartige Methode entwickelt, welche es bei minimalen Anpassungen am Anwendun...

The authors developed a binary tree search library. article presents UML diagrams of the classes. supposed Abstract factory design pattern for opportunity using trees’ node classes inheritance. unit tests one developed. This library can be used in creating scheduling technical maintenance calculation automated system and metro train energy optimal trajectory system.
