The Research On Optimization Of Railway Wagon Distribution Plan Of China

Empty wagons distribution is a part of railway technical plan,an excellent wagons distribution plan is an important means of achieving the goals of vehicle resources distribution reasonable and promote the balanced transportation and increase the Utilization of goods wagons.Thus,how to adjust the railway empty cars is not only a concerning problem to railroad department and also an important matters to revolution of freight marketing.Because the problem of empty wagons distribution is a difficult problem and it is influenced by many subjective and objective factors,so the problem of empty wagons distribution is a problem which is worth to investigate.This article mainly start from the following aspects:(1)To analyze and summarize the basic theory on empty wagons distribution and the current situation on empty wagons distribution of China.(2)Through a simple introduction about a problem of empty wagons distribution which is under the background of transportation problem,first of all,building a optimization model which is with the goal of maximize the benefits of Railway departments.Secondly,importing the factor of substitution of car types,and build an optimization of empty wagons distribution model which is under the under the condition of substitution of car types.Finally,importing the factor of the empty wagon needs of loading station,and build the model which is under the condition of substitution of car types and the time window of empty wagons needs.(3)Through introduce the theory on Genetic Algorithm,building a Genetic Algorithm which is adapt to the model of empty wagons distribution,and use the C programming to Calculate results.At the same time,use an example to verify the effectiveness of optimization model and algorithm.
