On probabilistic models for estimating the remaining useful life and depreciation of machinery and equipment

The author examines the life of the machine as a random variable, which is proposed to describe the probability distribution of Weibull that allows the dependence of the average remaining service life of the machine on its age. The features of the application of this method to assess the wear and proposed modifications to account for the time difference of benefits from the use of the machine. With a view to the practical application of research results highlighted three categories of vehicles, each of which are built according to the average remaining service life and wear factor of age.
