Abstract

Background. To increase the reliability and safety of complex critical systems during their long-term operation, it becomes necessary to use modern approaches to estimating the life and service life, taking into account the effect of time-past-present-future asymmetry.
Materials and methods. To realize this idea, the analysis of calculation of longevity indicators by traditional criteria of long-term strength and probabilistic-statistical methods for systems in which the required life and service life is 30–50 years or more, produced in small series, and sometimes even in single copies. It is shown that the use of modern methods of functional analysis can improve the accuracy of the forecast of the state of complex macroscopic technical systems.
Results and conclusions. Conclusions are made about the possibility of increasing the reliability and safety characteristics of the SSSF in applying a new approach that takes into account the time asymmetry factor in the theory of durability of complex technical systems. For example, the main theoretical foundation is the evaluation of the internal time of the functioning of systems.
