Аnnotation

An analysis of the literature data was applied, on the basis of which the research problem of developing a method for predicting the readiness for operational operation of the operational control chain was formulated, taking into account the influence of the structure of simultaneous redundancy of nodes and telecommunications channels, depending on the intensity of failures and restoration obtained from the operation results. Based on the unification and understanding of the connections of individual nodes and telecommunications channels of the operational control chain into a holistic system, an appropriate probabilistic model was synthesized, which takes into account the redundancy of nodes and telecommunications channels and the normalized intensities of failures and restoration of the equipment of nodes and telecommunications channels. The abstraction method was used to highlight a significant sign of readiness for operational operation, and reliability flowcharts and analytical expressions were developed for the probabilistic assessment of the readiness for operational operation of the operational control chain for various structures with separate redundancy of nodes and telecommunications chan-nels. By applying the method of mathematical modeling, the readiness for operational operation of the operational control chain was predicted. Based on the method of comparing the results of mathematical modeling for various redundancy structures, a stable, regular influence of the failure and recovery flow parameters on the readiness for operational work has been revealed. It has been established that to achieve the required level of readiness for operational work of the operational dispatch control chain, it is advisable to optimize the failure and recovery intensities and the multiplicity of redundancy of nodes and telecommunications channels, while the required readiness indicator is achieved by using double and triple separate redundancy of nodes and tele-communications channels of the operational dispatch control chain.
