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 into two levels. Then, a bilevel model for TSO was develop. Finally, this model was further illustrated by applying it on a railway station.
