Research On Optimization Of Shunting Organization Of Technical Station Based On Service Group Number

In order to better play the role of the technical station in serving the intermediate station,the relationship between the technical station and the intermediate station for traffic exchange is transformed into the connection in the respective shunting operation mode,and the shunting operation of different types of stations is adjusted as a whole The division of labor,and optimization of the shunting operation organization of the technical station,in order to achieve the improvement of the overall transportation organization efficiency in the region.The mutual service and mutual influence between the technical station and the intermediate station are realized by picking up and hanging the train.The technical station uses its own advantages to divide the service group number of the pick-up and pull-out trains according to the attributes of the cargo flow,and selects the marshalling content and train group sequence based on the service group number,which is more suitable for the pick-up and pull-up of the trains operated by the intermediate station,and maximizes the follow-up of the intermediate station.The operation link creates convenient conditions to achieve the purpose of high-quality service intermediate stations.The intermediate station strives to improve the purity of the departure vehicle flow through refined freight loading organization,vehicle flow collection and delivery,and arrangement organization,thereby reducing the workload of vehicle flow disassembly and assembly at the technical station.When the technical station selects and picks up and hangs trains based on the service group number,it should fully consider its own capacity constraints,and seek the optimal shunting operation cost classification line operation plan.The main research contents are as follows:(1)According to the current research status of train flow organization,shunting operations,and classification line application at technical stations at home and abroad,summarize and sort out the research status and deficiencies in the depth of selection and compilation of trains at technical stations,determine the research direction and goals of this article,and elaborate The practical significance of this research.(2)According to the basic theory of shunting work,this article summarizes the characteristics of different stations and different types of shunting operations,qualitatively analyzes the relationship between the technical station and the intermediate station when the train flow is exchanged by picking up and hanging trains,and the actual transportation and production.Deal with the problems in this relationship,and propose a collaboration model that is conducive to the improvement of the overall transportation organization efficiency and benefit between the technical station and the intermediate station based on this.(3)In order to realize the collaboration model between the above-mentioned technical station and the intermediate station,this article expounds the idea of dividing the service group number of the pick-up train according to the cargo area and cargo location,and puts forward the concept of dividing the service group number according to the cargo area and cargo location,and clarifies the service The division principle and method of the group number,and the economic benefit improvement brought by the division of the service group number according to the cargo area and cargo location is carried out in-depth analysis and calculation.(4)Aiming at the problem of selecting and picking up and hanging trains based on the service group number of the technical station,considering the adaptability of the dismantling capacity of the technical station and the ability of the sorting line of the marshalling yard,a mathematical model with the least operating cost of shunting during the selection and shunting was established.An effective algorithm is used to solve the optimal classification line application scheme for shunting operation cost,and examples are used to verify it.(5)Summarize the research work of this thesis,find out the deficiencies,and propose follow-up research directions.
