Statistical Analysis of Time of Establishing Steady Phases of Functioning of Complex Hardware-Software Systems

This article considers the problem of the statistical estimation of the time of steady phases establishing of the technical system operation when the transitions intensities are associated with the estimates, characterized by statistical uncertainty. In this case, estimations can be based both on the empirical data, limited in terms of their volume, and expert assessments. In this article it is shown that taking into account the statistical characteristics of the structure's components makes it possible to clarify an indicator of functional safety, such as the time of entering to a steady mode of functioning.
