PREDICTION OF REMAINING USEFUL LIFE TIME OF AERO ENGINE BASED ON THE WIENER PROCESS OF THREE-SOURCE UNCERTAINTY

Prediction of remaining useful life time of aero engine based on the Wiener process of three-source uncertainty

Given the problem of three-sources uncertainty in aero engine degradation process and the assumption s?n nhà màu n?u ??t of normal distribution of measurement error in existing research, a Wiener process aero engine residual useful life time(RUL) prediction method with logistic distribution of measurement error was proposed.Firstly, the performan
