Aircraft Combat Survivability Calculation Based on Combination Weighting and Multiattribute Intelligent Grey Target Decision Model

الملخص EN

Aircraft combat survivability is defined as the capability of an aircraft to avoid or withstand a man-made hostile environment, which has been increasingly important.

In order to give a rational calculation of aircraft combat survivability, an integrated method based on combination weighting and multiattribute intelligent grey target decision model is proposed.

Firstly, an evaluation index system containing susceptibility index and vulnerability index as well as their subindexes is established.

Then a multiattribute intelligent grey target decision model is introduced.

A combination weighting method is brought up based on a modified AHP (analytic hierarchy process) method and the entropy method, offering a rational weight for various indexes.

Finally, utilize the multiattribute intelligent grey target decision model to assess the aircraft combat survivability of aircraft, verified by a practical case of five aircraft.

The results show that the proposed method is effective and has a great value in engineering application, which will provide useful references for other projects’ evaluation.
