DEVELOPMENT OF A DISCRETE MODEL FOR ASSESSING THE EFFICIENCY OF FUNCTIONING OF SIGNIFICANT OBJECTS OF CRITICAL INFORMATION INFRASTRUCTURE IN THE CONDITIONS OF INFRASTRUCTURE DESTRUCTIVISM

The article presents the results of a study in the field of assessing the efficiency of functioning of significant objects of critical information infrastructure under conditions of infrastructural destructiveness using the developed universal discrete Q-model based on calculations of Markov chain nodes. The efficient functioning of significant objects is considered to be such a state of the system in which the value of the indicator of infrastructural destructiveness is in the acceptable range. The developed model was studied under conditions of infrastructural destructiveness in special cases with a differentiated number of effectively functioning objects. Based on the results, new patterns were established in modeling the assessment of the efficiency of functioning of critical information infrastructure objects. The value of the indicator of infrastructural destructiveness serves as an indicator of the efficiency of functioning of objects, that is, this indicator and the developed assessment model can be used as an element in the information security management system.
