A rail transit network restoration decision-making system and method aiming at improving toughness

Abstract

The invention discloses a rail transit network restoration decision-making system and method aiming at improving toughness. The system comprises a network topology structure module, a fault monitoringmodule, an action set generation module and an action decision module, wherein the network topology structure module is used for storing an actual rail transit network structure into the module, so that a computer can identify, store and process the actual rail transit network structure; the fault monitoring module is used for monitoring whether the rail transit network is completely connected ornot, receiving external fault information and generating a network adjacency matrix under a fault; the action set generation module is used for automatically generating a selectable repair scheme according to the type of the fault and available repair materials after the fault is detected; and the action decision module comprises a network toughness evaluation module and an optimal scheme recommendation module, and selects a scheme with the strongest toughness as a recommendation scheme by evaluating the performance of the network toughness under different repair schemes.

Description

Technical field: [0001] The invention relates to a rail transit network restoration decision-making system and method aimed at improving resilience, and belongs to the technical field of rail transit safety and emergency management. Background technique: [0002] The resilience of infrastructure systems is defined as the ability to predict, absorb, adapt to and quickly recover from potential disturbances. These disturbances or damages can be natural disasters, equipment failures, man-made damage, etc. The purpose is to reduce the amount of disturbances level, impact and duration. Since a good resilient design can better reduce the risk of the system collapsing under inevitable disturbance or damage, and improve the resilience of the system, it has attracted the attention of scholars and engineering designers at home and abroad in the past fifteen years. [0003] As an important part of public transportation, urban rail transit has the characteristics of large capacity, high...

Problems solved by technology

[0004] The current rail transit emergency handling is mostly focused on the selection of optimal evacuation routes, the design of the emergency dispatching command system, and the public transport linkage emergency transportation, etc., and has not yet focused on the decision-making of the repair plan for the network itself.
