Embodiment approach

[0082] In one embodiment, the method also includes the steps of:

[0083] Using the risk value of each leaf node in each associated node and the membership functions corresponding to multiple risk categories, respectively calculate the membership degree corresponding to each risk category, and obtain the membership degree vector of each leaf node.

[0084] Wherein, the nodes at the bottom layer of the tree model are leaf nodes. The risk value of the leaf node can be input by the user, or obtained by other means.

[0085] For example, the membership function is a piecewise linear function, and m risk categories determine m piecewise membership functions;

[0086] In one embodiment, the membership function may include a trapezoidal membership function, a parabolic membership function, a normal distribution membership function, a Cauchy distribution membership function or a ridge membership function.

[0087] For example, the risk category includes five categories, m=5, includi...

Abstract

The invention provides a flight operation risk calculation method, device and equipment and a readable storage medium, and the method comprises the steps: determining each associated node of a targetflight in a risk tree model according to each risk factor of the target flight; calculating a membership vector and a risk value of a parent node of the previous stage of the child node layer by layerby utilizing the membership vector, the weight and the fuzzy operator of the child node in each associated node; and taking the risk value of the root node of the risk tree model as the risk value ofthe target flight. According to the method, the risk tree model is established, and the risk value is calculated by adopting the membership degree based on the weight and the fuzzy operator, so thatthe obtained risk value is more accurate, accurate early warning can be realized, and the flight operation safety is improved.

Description

technical field [0001] The present invention relates to the field of aviation technology, in particular to a flight operation risk calculation method, device, equipment and readable storage medium. Background technique [0002] The current flight operation risk warning scheme usually uses a simple multiplication and division algorithm to calculate the total risk of the flight. Since there are many factors involved in risk warning, some factors have very high risk value, and some factors have very low risk value, resulting in inaccurate early warning results. Contents of the invention [0003] Embodiments of the present invention provide a flight operation risk calculation method, device, device and readable storage medium to solve one or more technical problems in the prior art. [0004] In the first aspect, an embodiment of the present invention provides a flight operation risk calculation method, including: [0005] According to each risk factor of the target flight, d...
