The methodology of formation and replenishment of typical situations basis in systems of decision making support on ensuring information security

Abstract

The presented article concerns the methodology of forming the standard situation basis in decision support system to provide information security based on the prin-ciple of separability. It is suggested to relate the present situation to one of the typical classes on the basis of un-certain close relationship between them. It is stated that the classification of situations on the principle of close represents a mathematical resolution of feature vector on some feature space basis. It is suggested to use algebraic procedure of feature vector resolution for similar situa-tions providing a better approximation to the reference sets in the sense of the least square deviation. The sug-gested methodology of forming and replenishment of the typical situation basis will help to effectively fulfill decision analysis and learn decision-maker’s experience.
