Description
Summary:The work carried out a theoretical study of the development of a mathematical hybrid model of risk assessment of the functioning of information modules of critical infrastructure objects in different modes, for proactive decision-making support. The model is able to assess the risks of the functioning of information modules, uses the intellectual analysis of experts' knowledge, reveals the vagueness of input estimates, increases the degree of validity of making further management decisions based on the obtained results. As a result, a vague aggregated assessment of the operation of the information module of the critical infrastructure facility was obtained; linguistic interpretation of the level of functioning of the module of the critical infrastructure object to support decision-making; the level of risk of functioning of the corresponding module. The developed model will be a useful tool for experts on the security of the operation of critical infrastructure objects in the framework of cybercrime prevention.
