A train dispatching model based on fuzzy passenger demand forecasting during holidays
Abstract: Purpose: The train dispatching is a crucial issue in the train operation adjustment when passenger flow outbursts.During holidays, the train dispatching is to meet passenger demand to the greatest extent, and ensure safety, speediness and punctuality of the train operation.In this paper, a fuzzy passenger demand forecasting model is put u
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 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 Clasps measurement error was proposed.Firstly, the performance degradation
