The article considers the determination of the optimal operation of the main apparatus – the distillation column for the production of oxygen, argon and nitrogen. The main purpose of the study is to determine the optimal modes of operation of the column. Production, depending on the needs of the product(s), operates in one of four modes – nitrogen mode, oxygen mode, oxygen-argon mode and oxygen-argon-nitrogen mode. The novelty of the work is the formulation and solution of scalar and vectorial optimization problems in all modes of operation of the distillation column. The article uses methods of identification, defasification and optimization. The optimal operating mode of the column is determined on the basis of deterministic equivalents of fuzzy Mamdani-type models obtained with the help of experts. The practical significance of the work is to improve the quality of production products. Examples of setting and solving optimization problems for all modes of production are given.

Keywords:multi-criteria optimization, fuzzy models, defazzification, weight coefficients, operating mode.
