VERIFICATION OF RELIABILITY TECHNICAL DEVICES THROUGH RESOLVING PROBABILITY OF FAILURE AND FAILURE

This article describes the basic concepts and definitions of reliability theory and its applications to problems of probability theory. Probability theory makes it possible to take into account the random nature of events and processes occurring in the system, to form the mathematical foundations of the theory of reliability. The problems on the probability of failure-free operation of the element are considered.One of the main tasks solved in the course of operation and maintenance of technical devices is to ensure their reliable operation. The importance of this problem is due to the complexity of modern technical devices and high values of operating loads (temperature, pressure, humidity, etc.). Reliability refers to the ability of technical devices to perform specified functions, maintaining their performance within the specified limits for the required period of time or the required operating time in certain operating conditions.Reliability as a qualitative characteristic has always been taken into account when solving various issues of operation and maintenance.
