Method of determining the criticality of elements of a complex technical system

The importance of information and infrastructure increases every year. The criticality of such assets is determined by the impact of disruptions to their stable operation. This paper develops an approach to determining the criticality of communication system elements. It is based on the use of a system performance profile during the construction and operation of the system. Determining the importance of each element within the communication system will ensure the stable operation of the system, aimed at fulfilling the required number of tasks and functions.
