Abstract:

      This paper presents an optimization approach for rolling stock assignment of urban rail transit network to response the new tendency of urban rail transit from singlerail to network operation. We further give the singledepot and multidepot rolling stock assignment models. We solve the problem by ILOG CPLEX 12.5 and combination with a numeric example. It is proved to be effective by comparison with a heuristic algorithm. Result proves that the method can provide a good reference for rolling stock assignment in urban rail transit network.

Key words: urban rail transit, network flow model, rolling stock assignment
