The study set the goal of improving the efficiency of various technological schemes of purification plants of the enterprise through the development of an expert system based on fuzzy logic methods and the formation of practical recommendations for improving the characteristics of wastewater from the operation of schemes of purification plants.

Models based on regression analysis for predicting the operational efficiency of high-pressure roller crushers are considered. A systematized and structured production database is created and statistically analyzed. The consistency of the data is verified. The parameters with the greatest influence on the productivity are identified. The basic structure of the mathematical models is determined, and the limits on their applicability are assessed. Predictive mathematical models are developed. Their adequacy is verified, and their precision is established in assessing the productivity of mills at an enrichment plant where the mineral composition of the incoming ore varies.
