Abstract:

Evaluating the resilience of the high-speed rail temporal network is of great significance for analyzing the high-speed rail system structure and dispatching the operation of high-speed rail trains.This paper aims at the temporal and spatial attributes of disaster factors that are not well considered in the existing resilience studies of complex transportation networks,in which a new model of the analysis of the resilience of the high-speed rail temporal network is proposed based on the differences between nodes in the time and space dimensions of the network being attacked by different disasters.First,high-speed rail temporal network model is built based on the time sequence of the high-speed rail passing through stations and the spatial relationship between the stations.The resilience index is introduced to evaluate the resilience of the high-speed rail temporal and spatial network under normal conditions.Then,according to the entropy weight method,the weight of different disasters is determined,and an evaluation model for the resilience of the high-speed railway temporal network under multiple disasters is constructed,the resilience of high-speed rail temporal networks is evaluated under disaster situations through resilience indicators.The simulation experiment selects the operation data of China's high-speed rail and the historical data of the past ten years of disasters such as rainstorms and earthquakes,and compares the resilience evaluation model in this paper with two commonly used complex network resilience evaluation models.Experimental results show that compared with the traditional resilience assessment model,the final resilience loss ratio of the resilience assessment model in this paper is reduced by 0.61%,which is more in line with the process of the actual high-speed rail network affected by disasters,indicating that the model have a good theoretical value and practicality.

Key words: complex networks, resilience, temporal and spatial attributes, entropy weight method, heterogeneous disaster
