Management of ecological and economic security of industrial enterprises

The purpose of this study was the modeling of ecological and economic security of production processes in an industrial plant using methods of fuzzy logic. The subject of the research - methods of modeling systems of ecological and economic security of industrial enterprises, based on the adaptation of fuzzy set theory to solve this problem. In the research process the following scientific methods and techniques were applied: scientific abstraction, analysis, synthesis, methods of grouping, comparison, etc. Along with the traditional methods the authors used the tools for simulation modeling, fuzzy sets systems, computer simulation MatLab. The informational and empirical basis of the research was formed on the basis of the data of the Federal service of state statistics and its territorial subdivisions of the Ministry of economic development of the Russian Federation, e-resources of the Internet, the research by Russian and foreign scientists, experts' assesments. The article presents the author's method of ensuring ecological and economic security in the enterprise by means of fuzzy logic, based on the quantitative assessment of indicators of threats in MatLab and results of visualization of fuzzy-multiple modeling of ecological and economic security. The algorithm of calculation of the conditional environmental pressures on water resources and the atmosphere, allowed to determine the dependence between the cost of wastewater treatment and economic damage from pollution and to evaluate the effectiveness of various conservation programs, and to analyze their impact on environmental sustainability. The authors also develop complex fuzzy models and implemented their software in the MatLab Fuzzy Logic Toolbox, which allowed to obtain an integrated assessment of the state of the enterprise environmental safety and comparisons of the values of these threats based on assessment. The author presents the author's methodology and the evaluation of software implementation of ecological and economic security, the adequacy of the proposed model and the calculation of its economic efficiency.
