Embodiment Construction

[0037] The method for quickly identifying and eliminating the bottleneck of high-speed railway transport capacity in the present invention starts from the line point of view, considers the coordination and matching of point and line capacity, and integrates the passing capacity of stations and sections to find key points that affect the line transport capacity. The management provides key technical support to ensure the normal operation of trains on the line.

[0038] The method of quickly identifying and eliminating the bottleneck of high-speed railway transportation capacity takes each station and section on the researched line as a research object, and first calculates the theoretical passing capacity value of the station and section according to the theoretical mathematical analysis method. For the set operation diagram, the operation diagram is compressed by eliminating the buffer time, so that the capacity of each station and section before and after compression can be us...

Abstract

The invention relates to a method for quickly identifying and eliminating the transportation capacity bottleneck of a high-speed railway, comprising the following steps: A. on the basis of taking each station and section on a researched line as research objects, successively obtaining the capacity utilization ratio of each researched object by a theoretical analysis method, a train diagram compression method and a system simulation method for a set train diagram; B. carrying out weighted average on the three utilization ratios of each researched object, and taking the research object with themaximum average utilization ratio as a relative bottleneck point for the line transportation capability; C. judging the capability utilization ratio of the bottleneck point, and if the capability utilization ratio is more than a set value, circulating the utilization ratio computation methods by selecting an adjusting scheme until the capability utilization ratio is less than the set value; and D. identifying the bottleneck again for the line until the utilization ratio of the found relative bottleneck point is less than the set value. The method for identifying and eliminating the transportation capacity bottleneck of the high-speed railway is effective and quick, thereby providing a technical support for trains to safely and punctually operate.

Description

technical field [0001] The invention relates to a method for quickly identifying and eliminating the bottleneck of high-speed railway transportation capacity, which is applied in the field of high-speed railway transportation organization. Background technique [0002] The early research on the problem of transportation capacity mainly focused on the basic concepts of various capacities and the calculation and determination of the capacity of each individual equipment. As early as 1878, Russia Berkhovsky first began to study the passing capacity, and then some scholars began to study Calculation of passing capacity of parallel running diagram and non-parallel running diagram, literature review of optimal allocation of railway transportation capacity and resources, related concepts and theories of force have become an important branch of railway transportation management discipline after more than a century of research and development. The former Soviet Union and my country h...
