Method and system for evaluating flight string fatigue grade based on task information

A system for evaluating a flight string fatigue grade based on task information, comprising a collection module, a system construction module, a processing module, a calculation module and an analysis module;

• wherein the collection module is used for collecting task information of a flight string, and extracting first factors influencing a flight string fatigue degree based on the task information;
• the system construction module is used for constructing an index evaluation system based on the first factors, and calculating a weight coefficient of each of the first factors;
• the processing module is used for carrying out a segment processing on the task information to obtain duty period segments;
• carrying out a quantitative characterization on the each of the first factors to obtain factor intensities of the duty period segments;
• the calculation module is used for calculating first fatigue values of the duty period segments based on weight coefficients and the factor intensities;
• and
• the analysis module is used for calculating a second fatigue value of the whole flight string based on the first fatigue values;
• and determining a flight string fatigue grade based on the second fatigue value.
