“…In addition, thanks to the development of technical diagnostic systems, the number of technical indicators that are heterogeneous has increased. They are also subject to integration in the process of assessing the state of the object for the adoption of one of the three decisions: (1) Prolongation of its operation with standard parameters, or with their limitations; (2) repairs and upgrades with subsequent use in order; (3) decommissioning.…”

The amalgamation procedure is actual when using structural methods of reliability. This may apply as the case of the action of a complex of damaging processes on a structural element and the case of the action of a certain damaging process on a system of elements. Classical methods of reliability are poorly adapted for powertrain mechanical systems with a series structural scheme of elements subjected to the gradual influence of several degradation processes. The problem of amalgamation of individual indicators is exacerbated at the stage of operation when diagnosing the technical state of the mechanical system. The application of the classical rule of amalgamation by multiplying the probabilities of survival leads to the effect of over-maintenance. New rules of amalgamation have been developed, which deprive the assessment of the reliability of excessive conservatism. The complex index of the technical condition is offered-the resource safety index (RSI). Its use determines the remaining lifetime. The algorithm for searching the RSI contains an assessment of the criticality of the failure. The search of RSI under the influence of the complex of damaging processes on the element of the powertrain system is demonstrated. The efficiency of the RSI method is shown by the example of the reliability assessment of aircraft bolts. Application of the RSI method increases the guaranteed lifetime by 4-10 times compared with traditional methods.

“…1). In the individual approach, probabilistic-physical methods are used, taking into account the nature of the degradation processes (the failure physics) and the mutual influence of elements [2,3]. In the modern theory of maintenance, the boundary condition is determined by the moment of transition of the system to the corresponding phase of the technical condition, the number of which quantity tends to increase [3].…”
