Embodiment Construction

[0031] Below, the present invention will be further described in conjunction with the drawings and specific embodiments.

[0032] like figure 1 As shown, a helicopter flight risk assessment method based on AHP, including the following steps:

[0033] (1) with figure 2 As an example, build a flight risk assessment index system based on three factors: personnel, helicopters, and the environment; specifically:

[0034] (101) A flight risk assessment personnel index system based on personnel factors, including but not limited to physiological state, psychological state, and illegal operations;

[0035] (102) A helicopter flight risk assessment index system based on helicopter factors, including but not limited to stand-alone technical status and engine technical status;

[0036] (103) An environmental indicator system for flight risk assessment based on environmental factors, including but not limited to meteorological environment, geographical environment, and biological envi...

Abstract

The invention discloses a helicopter flight risk assessment method based on an analytic hierarchy process, and belongs to the field of helicopter flight risk assessment. Aiming at the problem that a current helicopter monitoring system does not monitor a flight risk problem, the method considers factors such as personnel, helicopters and environments influencing the flight risk, and comprises the following steps: firstly, constructing a flight risk assessment index system, then constructing a fuzzy consistent matrix according to the importance of assessment indexes, and calculating index weights; and according to the actually collected flight risk related data, the flight risk state is evaluated. The method has the advantages of being high in calculation efficiency, high in universality and easy to implement.

Description

technical field [0001] The invention relates to the technical field of helicopter flight risk assessment, in particular to a helicopter flight risk assessment method based on analytic hierarchy process, which can be used for automatic analysis of the risk status of helicopter flight activities. Background technique [0002] Due to the precise structure of the aircraft, complex human factors and changing natural environment, aviation accidents continue to occur. Among them, helicopters have more frequent flight accidents due to their low flying altitude and vulnerability to clouds and fog, resulting in huge casualties. loss, economic loss and negative social impact. [0003] A large number of after-the-fact accident analysis shows that most of the flight accidents can be pre-warned through various signs. Using fuzzy analytic hierarchy process based on multi-objective decision analysis can well cover the evaluation indicators involved in helicopter flight risk, and realize fl...
