Title:
EVENT TREE-BASED FLIGHT EXCEEDANCE EVENT COMPREHENSIVE CONSEQUENCE SEVERITY CALCULATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/108928
Kind Code:
A1
Abstract:
The present invention relates to the technical field of flight data processing and analysis, in particular to an event tree-based flight exceedance event comprehensive consequence severity calculation method. The method comprises the following steps: constructing a native exceedance event tree model, wherein the native exceedance event is taken as an initial event, and at least one secondary exceedance event is taken as a result event; and performing flight exceedance event comprehensive consequence severity calculation, taking a set of the secondary exceedance events as a factor set, taking severity levels of the secondary exceedance events as an evaluation set, calculating a membership degree of an evaluated type on each factor for each type in the evaluation set according to the evaluation set and the factor set, forming a fuzzy matrix according to the membership degree, taking a path length of the secondary exceedance event, distant from the native exceedance event, on the native exceedance event tree model as a weight, and quantitatively calculating the flight exceedance event comprehensive consequence severity on the basis of the fuzzy matrix and the weight. According to the method, the flight exceedance event consequence severity is comprehensively and clearly evaluated.
