Abstract

In order to evaluate complex system in selection of aircraft scheme, the evaluation method based on cloud model was utilized. This paper analyzed the evaluation steps based cloud model. Because of imprecision in judgment from cloud model figure in past, the measurement method of cloud comparability was introduced to judge which rating the evaluation result belongs to. Finally, the application in the use of the design in certain Vertical/Short Takeoff and Landing (V/STOL) aircraft proved the validity of the evaluation method. The results indicate that the evaluation method based on cloud model can give consideration to both randomness and fuzziness of complex system, and can effectively evaluate the aircraft scheme.
