Motor train unit application plan compilation method considering intra-weekly fluctuation of train operation scheme

Abstract

The invention relates to a motor train unit application plan compilation method considering intra-weekly fluctuation of a train operation scheme. Based on the motor train unit application mode of the semi-fixed operation section, part of motor train units adopt the application mode of the fixed operation section to serve as part of fixed running trains, and part of motor train units adopt the application mode of the unfixed operation section to serve as part of fixed running trains and unfixed running trains; a motor train unit application problem is converted into a traveling salesman problem (TSP problem), and a motor train unit traffic daily plan optimization model and a motor train unit application weekly plan optimization model which meet motor train unit maintenance requirements are established by constructing a motor train unit application continuing network and performing hierarchical modeling; and performing staged solution according to the hierarchical model, and designing a motor train unit application plan optimization algorithm based on an ant colony algorithm to obtain an optimized motor train unit application weekly plan. The method can recombine transportation resource supply to efficiently improve the quality of transportation products and meet the diversity of passenger flow demands.

Description

technical field [0001] The invention belongs to the field of compiling operation plans for high-speed railway EMUs, and particularly relates to a method for compiling an EMU operation plan considering intraweek fluctuations in train running plans. Background technique [0002] Scholars at home and abroad have carried out a lot of research on the preparation and optimization of the high-speed railway EMU operation plan. Due to the large differences in the transportation organization level of high-speed railways at home and abroad, the relevant research on the use of EMUs cannot be fully adapted. At present, my country's EMU resources are relatively scarce, and the demand for passengers is increasing day by day. The realization of EMU operation under complex backgrounds such as "one picture a day" has become the focus of the next research. Moreover, at present, there are few studies on the weekly planning of EMU operation and the preparation of EMU operation plans in large-sca...

[0005] (2) When the train operation plan changes dynamically, the dynamic control of the EMU resources is poor

In the existing research, the optimization of the operation plan of the EMU is mostly based on the single-day train operation diagram, and the generation of the crossing section (referring to the set of train tasks performed by the bottom of the EMU within a certain period of time) and the splicing of the crossing section are carried out in two stages. , this method has a good effect on the optimization of the EMU single-day operation plan under the fixed train operation plan, but when the train operation plan fluctuates within a week, it is difficult to implement the EMU weekly operation plan in this way.
