The invention provides a railway freight train formation car number model building method based on operational effectiveness optimization. The method comprises steps: a customer choice probability model for different transport modes is built; a generalized cost model for transport modes chosen by customers is built; a service characteristic coefficient calibration model in the generalized cost model is built; according to the customer choice probability model, the generalized cost model and the calibration model, an average waiting time range of railway goods is acquired; an operating income model for railway freight trains is built; an operating cost model for the railway freight trains is built; a transport volume model for the railway freight trains is built; and according to each model, a railway freight train formation car number model is built. Through building the final railway freight train formation car number model, the model is adopted to acquire the corresponding formation car number and the starting frequency times in the case of the operational effectiveness optimization, the railway freight trains are organized to start according to the acquired formation car number and the starting frequency times, and the purpose of achieving the freight operational effectiveness optimization is realized.
Description
technical field [0001] The invention relates to the technical field of railway transportation, in particular to a method for establishing a vehicle number model for railway freight train formation based on optimal operating benefits. Background technique [0002] For a long time, my country's railway freight transportation organization model has been mainly oriented towards internal production, with little regard for the transportation needs of customers. [0003] Most of the research on the railway freight train operation plan is based on the existing freight volume of the railway, and the freight volume is predicted through historical data. The number of trains is usually regarded as a constant (empirical value) or given The research on the number of trains is mostly based on the problem of vehicle flow assembly at the marshalling station, and rarely considers the generation cycle of customer supply and the frequency of transportation demand, which leads to the lack of mar...
