Train-Scheduling Optimization Model for Railway Networks with Multiplatform Stations

A Bilevel Model for Railway Train Set Organizing Optimization

Train Set Organization (TSO) is to arrange the train set in railway freight transportation. Bilevel programming techniques were proposed to solve the Stackelberg game in which play is sequential and cooperation is not permitted. In this paper, an optimizing model for TSO is developed by the bilevel techniques. First, we analyzed the multiple level nature of management on TSO and simplified it i...

Optimization in railway scheduling

Train scheduling has been a significant issue in the railway industry. Over the last few years, numerous approaches and tools have been developed to aid in the management of railway infrastructure. In this paper, we describe some techniques, which was developed in a project in collaboration with the Spanish Railway Infractructure Manager (ADIF). We formulate train scheduling as constraint optim...

Optimal Trajectory Planning and Train Scheduling for Railway Systems

A discrete-event optimization framework for mixed-speed train timetabling problem

Railway scheduling is a complex task of rail operators that involves the generation of a conflict-free train timetable. This paper presents a discrete-event simulation-based optimization approach for solving the train timetabling problem to minimize total weighted unplanned stop time in a hybrid single and double track railway networks. The designed simulation model is used as a platform for ge...

Intelligent Train Scheduling on a High-Loaded Railway Network

We present an interactive application to assist planners in adding new trains on a complex railway network. It includes many trains with different characteristics, whose timetables cannot be modified because they are already in circulation. The application builds the timetable for new trains linking the available time slots to trains to be scheduled. A very flexible interface allows the user to...
