Abstract

Despite the large amount of discussions concerning the definition of technical condition of complex technical systems (CTS) on risk assessment, the most vulnerable interrelated and interacting components of such systems in various emergency scenarios when assessing the structural and functional risks are still determined as a result of complex procedures, containing nonlinear operations.In this paper, the CTS structural and functional risk assessments in emergency scenarios were defined using the cognitive simulation model, represented as a directed graph, as well as by the calculation results. Destructive transmission pulses are used for modeling the destructive effect of each component on the CTS structure. Normalizing effect on the vertices and edges of the model digraph is used to assess the CTS functional risk.A software package is presented in the paper, and the calculation results of assessment of structural and functional risks of interrelated CTS components, obtained with its help are described.The results of development and research, which consider the structural and functional features, interrelation and interaction of elements and inter-element relations in the CTS hierarchy and topology in emergency scenarios are given. The method for assessing the structural and functional risks does not contain labor-intensive, complex procedures and will allow to automate the decision-making process in CTS emergency scenarios.
