Embodiment

[0070] like figure 1 As shown, it is a flow chart of an airport network risk assessment method under severe weather of the present invention, comprising the following steps:

[0071] S1: The vulnerability assessment value of the computer farm network.

[0072] The airport network takes the airport as a node of the network (referred to as an airport or an airport node), and the air route between two airport nodes is used as an edge of the network. The vulnerability is the degree to which the subject (that is, the airport network in this embodiment) is vulnerable to damage when it is induced by external risks, and can be used as a measure of the risk probability of the airport network being damaged under severe weather.

[0073] Specifically, the historical data that the airport network is affected by bad weather is obtained, the single airport vulnerability value of each airport under bad weather is calculated, and the vulnerability assessment value of the entire airport netwo...

Abstract

The invention discloses an airport network risk assessment method under bad weather. Obtain the vulnerability assessment value of the entire airport network under bad weather; calculate the operating efficiency drop value and capacity drop value of the airport network respectively under bad weather, and couple the operating efficiency drop value and capacity drop value to obtain the airport network The functional loss index evaluation value of the airport network is obtained; the vulnerability evaluation value of the airport network and the functional loss index value are coupled to obtain the macro risk evaluation value of the airport network. It can obtain numerical risk assessment value, which is intuitive and reliable.

Description

technical field [0001] The invention relates to the technical field of civil aviation risk assessment, and specifically discloses an airport network risk assessment method under bad weather. Background technique [0002] With the rapid development of China's civil aviation field, the contradiction between limited aviation resources and the rapidly growing air transport has become increasingly intensified. As the carrier of air transport, the airport network, as the carrier of air transport, its operational safety risks have become increasingly prominent as the contradiction deepens. Due to the large scale, high complexity and numerous risk factors of the aviation network, through the investigation of the current situation of civil aviation operation risks in my country, it is found that severe weather is the most important risk factor causing abnormal civil aviation flights and accidents in my country. The hazard of spatial characteristics, through the damage to airport nodes...
