Research on anti-icy system reliability evaluation based on isomeric grey information fusion
Wen Qian Song, Jianjun Zhu · 2011
Grey information fusion problem is studied in the complex commercial aircraft anti-icing system for the reliability evaluation. Since the reliability of commercial aircraft anti-icing system is immeasurable, the experience of experts must be fully relied on. Firstly, the heterogeneous grey information is processed into interval grey numbers or intrinsic grey numbers; Secondly, based on the consistency of evaluation information and the principle of minimizing interval grey weight deviation, the interval grey weight modeling method is proposed; Thirdly, the nonlinear aggregation model of interval grey method is built; Finally, the reliability evaluation methodology of commercial aircraft anti-icing system is applied to a numerical example.
