The competition among the container transport companies grows more and more vehement,however,the management levels and methods of those companies have not been increased accordingly. Based on analyzing a lot of restrictions elements in the multimodal transport system,from the view of realizing profit-maximizing of the transport operators,a cargo container transport schedule optimization model is constructed,according to this kind of Integer programming model,a corresponding example to is also give verify the validity of the model.

Train operation adjustment is to change the arrive-departure time at the station and running time at the interval to improve punctuality when a train is delayed.With the current situation and development prospects of China's railway,a graph theory mode of train operation adjustment is proposed and the corresponding integer programming model is formed.Example is solved with heuristic algorithm in C language,and is analyzed and compared in different results.
