Use of the Theory of Fuzzy Sets in Determining the Level of Enterprise Security

Abstract

The concept of “enterprise security” and the factors that determine it are considered in the paper. A mathematical model based on the theory of fuzzy logic and linguistic variable to determine the level of enterprise security is proposed. Each of the proposed influencing factors is characterized, a universal set of variations and linguistic terms for evaluation are developed. It is proposed to divide the factors into five groups: legal, financial and economic, informational, technical, energy. A tree of logical inference of the hierarchical connection of factors is offered. A mathematical model is implemented in a specialized free package FisPro. Based on the simulation results, the level of security of the real enterprise is determined and the main recommendations for its improvement are given. The use of the proposed mathematical model will allow a comprehensive assessment of the level of security in any enterprise.
