The relevance of the research is caused by the need to ensure optimal ratios of the octane number of gasoline and the cost of organizing the process in a catalytic reformer with a capacity of 1 million tons per year for raw materials in conditions of variable quality of raw materials and quality of fuel gas. The effectiveness of gasoline production depends not only on increasing the octane number, but also on reducing the costs of the process organization. The existing systems for controlling the catalytic reforming do not ensure the achievement of optimal ratios of the octane number of gasoline and the costs of the process organization. It is necessary to develop a control system for the catalytic reforming process, which ensures the achievement of these ratios. The main aim of the research is to achieve optimum octane number ratio of gasoline and process organization costs in a catalytic reformer with a capacity of 1 million tons per year for raw materials in conditions of varying quality of raw materials and quality of fuel gas by developing a management system. Object of the research is the catalytic reforming unit with a capacity of 1 million tons per year for raw materials. Methods: fuzzy sets theory, decision theory in fuzzy conditions, computational mathematics, automatic control theory. Results. The authors have set the task of controlling the process of catalytic reforming at a L-35-11 / 1000 reformer with a capacity of 1 million tons per year for raw materials and carried out the analysis of the process as a control object with the identification of its features. The paper describes the set of input and output parameters of the control object and introduces the expression for determining the generalized optimality criterion. The authors developed the system for controlling the catalytic reforming. The implementation of the proposed system ensures the achievement of optimal ratios of the octane number of gasoline and production costs.
