Aerospace Instrument-Making Annotation << Back Method of Assessing the Reliability Function of Technological Equipment by Gradual Failures Based on the Results of Maintenance Factor Prediction Stelmakh S.F., Lyashevsky A.V., Ginzburg T.V., Demidova N.S. The article describes the economic and technical feasibility of assessing the reliability function of technological equipment by gradual failures based on the results of maintenance factor prediction in order to determine the residual life, and implement measures for maintenance and repair. A method has been developed for assessing the reliability function on gradual failures based on the results based on the results of maintenance factor prediction. Using a specifi c example of the initial data, calculations have been made of the reliability function values over a certain time interval to determine the technical condition of the equipment. The practical significance of the presented method is shown. Keywords: Reliability function, failure, maintenance factor, technological equipment, prediction, residual life.
