A method for assessing the resistance of distributed networks of electronic communications for special purpose from the position of the theory of risk management

Abstract

The diversity of special-purpose electronic communications networks, their destruction and restoration processes make the problem of developing methodological bases for evaluating their key characteristics highly demanded during operational calculations by officials of communication management bodies. The problem of rational and optimal use of the resources preserved in the system aimed at performing critically important functions of the system after the intense impact of external destabilizing influences on it remains just as relevant. Solving this problem requires new qualities from the system, which it may not have if it is designed to work only in certain operating conditions. In view of the above-mentioned problems with the properties of survivability and their features, which are widely used in the creation of complex systems of various purposes, a number of special requirements are put forward that relate to both the structural and functional parts of complex systems. One of the natural indicators of the quantitative measurement of the effectiveness of special purpose electronic communications networks is the survivability index that has remained in the system after a fixed set of destabilizing influences.The efficiency indicator is a measure (metric or in the form of a scale of points in the appropriate modifications) of the degree of compliance with the required real result of the performance of the established functional tasks, after the impact of destabilizing influences. In order for the performance indicator, determined on the basis of many strategies, to be considered as a characteristic of the functioning of the system, it must satisfy the following requirements: content and interpretability, measurement, compliance with the system of preferences of the decision-maker. Since the decision of the person making the decision on the construction and combat use of special-purpose electronic communications networks is decisive, it is advisable to calculate the network efficiency indicator from the standpoint of the risk management model.
