A method for selecting a multi-target location of hierarchical rescue station for urban rail transit

Abstract

A method for selecting a multi-target location of hierarchical rescue station for urban rail transit features. The method includes establishment of the rescue station network-vulnerability assessment,vulnerability classification, and determination of the coverage function. establishment of a multi-objective location model suitable for urban rail transit level rescue station planning decision-making, and algorithm design; from economy, efficiency, coverage, the accuracy and rationality of the location method of the rescue station is improved, and finally rapid rescue response and efficient material supply can be achieved. The method can effectively reduce the construction and maintenance cost of the rescue network, but also ensure the efficient and timely rescue of emergencies. It can provide rail transit enterprises with location decision-making schemes with different decision-making preferences to meet the needs of actual site selection work.

Description

[0001] Field [0002] The invention belongs to the technical field of emergency management of urban rail transit, and in particular relates to a multi-target site selection method for hierarchical rescue stations of urban rail transit. Background technique [0003] The urban rail transit emergency rescue station is a facility specially used to store emergency supplies. During the emergency rescue process, the emergency rescue station is at the core and undertakes a series of activities such as the gathering and distribution of emergency supplies. Therefore, whether the location of the emergency rescue station is scientific and reasonable will largely affect the ability of the entire line network to resist emergencies and the efficiency of rail transit enterprises in dealing with emergencies. At the same time, due to the high construction cost of the emergency rescue station and the difficulty of address relocation, if the setting of the rescue station cannot meet the actual re...

Problems solved by technology

In our country, the degree of rail transit network in each city is not high, and a complete management system has not been formed in the daily operation organization and emergency response process. The concept of emergency management still focuses on the previous single-line thinking, causing each line to form its own system , fighting independently, so it is easy to have the problem of repeated resource allocation and inability to share; on the other hand, the research on the site selection of emergency rescue stations lacks the thinking and design of the network level, and the research at this stage tends to ignore the network topology of the rail transit system In addition, most of the existing research focuses on the theory and method of site selection, and seldom combines my country's Empirical Analysis of the Actual Status of Rail Transit
