The algorithm for ensuring the parts’ (assembly nodes, machines) reliability based on the theory of risk

Abstract

Abstract currently existing technical systems are created for a certain service life with a limited number of work cycles and are out of order after some time. At the same time, there are such failures that cause life loss, damage at various levels. Therefore, there is a need to use the “risk” concept of an adverse event (excluding damage). The considered risk exceeds the failure probability by the safety factor value. The article presents an algorithm for ensuring the reliability of the parts associated with negative consequences, based on the risk theory, which considers the patterns (Figure 8 - Figure 10), due to six scientific principles.
