To adjust user/infrastructure requirements and obtain different solutions, analyze them, and take decisions about both railway traffic conditions and the available railway infrastructure. Figure 1 shows the basic architecture of MOM. We have structured MOM in two main components: the interface and the optimizer.
In high-density railway sections such as metropolitan commuter lines, there is a great demand for increasing train density in order to relieve traffic congestion. However, it becomes more difficult to shorten train headway, as the track layout, train type and so on become more diverse. Therefore, making train diagrams needs the expertise of skilled specialists. In order to raise the train density, this paper aims to calculate the train minimum intervals between all trains within a certain accuracy and derive an original train diagram.
This process can take a long time and it usually stops once a feasible timetable is found. The difficulty of the process increases in complex and high-loaded networks and the resulting timetabling may be far from optimal. In this work, we present MOM: a friendly, flexible, computer-based Decision Support System (DSS) whose main goal is to support the railway planner to efficiently obtain optimized train timetables. The system generates feasible and high quality timetables by considering the set of constraints of the problem and optimization criteria related to the use of railway infrastructures and operator requirements.
