The Research On The Optimization Of Motor Train Sets Scheduling And Service-Repariring Of High-Speed Rail Way

Motor Train-set Routing Problem is one of the most important issues of High-speed Railway's regulation and routing, which matters the quantity of financial investments on equipment and the reasonable organization of transportation. However, those problems are settled by Motor Train-set Plan totally, including the routing ways and service-repair of Motor train are solved too. Therefore, the optimization of Motor Train-set Plan and the optimization of service-repair of motor train that this thesis focused on is not only two problems a raised by Motor Train-set Routing Problem, but also problem of the extension of Motor Train-set Plan. In order to fill the vacancy left by the former scholars, and to meet the needs of the transporting organization of High-speed Railway, the author venture to discuss the two problems in his thesis, with the hope of benefiting the Motor Train Routing.The thesis analyzes those factors that extend influence on the efficiency of Motor Train Routing, discusses the intonation, extension and coding process of Motor Train-set Plan, points out the binding conditions of Motor Train Routing Ways and the influences of the men-in- charge's will on the coding process of Motor Train Routing, and states the difficulties of using computer automated coding of Motor Train-set Plan. Based on the former theories, the author of this thesis continues with the study of Motor Train-set Plan and service-repair of Motor train in a deeper way. With the arm of co rectify the speed index of the Motor Train Routing and the times index of service-repair of Motor train. Firstly, the author tries to establish a system of evaluation index and a model and steps of optimization on Motor Train Routing, points out how to adopt the objective and subjective synthetic approach to solve the optimization problem, and work out the influence of the willing of the person in charge. Secondly, the author analyzes the proceeding characteristics of the repairing system, and illustrates how does queueing theory work in that condition. Finally, the author uses the M/M/m/n/n to deals with repair position, and proves that the analytic formula of repair position can be well settled under such kind of theory model.
