Aircraft event investigation system performance evaluation method and system

Abstract

The invention discloses an aircraft event investigation system efficiency evaluation method and system. The method comprises the following steps: S1, constructing an evaluation index system and historical sample evaluation data; s2, inputting the normalized historical sample evaluation data into an index weight assignment model, and obtaining the weight corresponding to each index by the index weight assignment model through P calculation modules; s3, constructing a combination evaluation model based on deviation maximization, taking the index as an evaluation object, and calculating to obtain a combination evaluation weight corresponding to the index; and S4, evaluating to obtain evaluation data of each index based on the evaluation index system, and calculating to obtain an efficiency evaluation result. According to the invention, each calculation module of the index weight assignment model obtains a weight corresponding to each index, and then a combination evaluation model is constructed to obtain a combination evaluation weight corresponding to the index based on deviation maximization calculation, so that an index evaluation result corresponding to each index and a final efficiency evaluation result are obtained.
