Given the problem of three-sources uncertainty in aero engine degradation process and the assumption 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 performance degradation model was established when the measurement ... https://www.sunsetnoveltiers.shop/product-category/general-items-for-adult-toys/
