Research on the Model for Route Selection of Railway Pickup and Delivery Service

摘要

With economic expansion having moderated to a "new normal" pace, the railway freight market share continues to be sluggish, and China's railways are transforming into modern logistics and carrying out pickup and delivery services. This paper mainly focuses on the transportation lines of the external operations of the station. It is fully analyzing that the transferring of the railway is highway transportation for the connection between the customer and the station. According to the mixed integer linear programming model with 0-1 variables based on comprehensive cost optimization, this paper built the model of pickup and delivery route selection, to determine the running route of the vehicle during the service process, as well as make sure the requirements of each customer can be satisfied and the total cost is considering. LINGO12.0 is used to calculate the optimal solution, and we optimized the railway pickup and delivery service route. Finally, the model is validated by the data of one day's bulk cargo pickup and delivery at a railway station of Shanghai as an example.
