It is shown that the development of systems and aids of mathematical modeling of alumina production at the refinery of Russia has passed a long way of evolution and it is mainly connected with creating the specialized software products and domestic mainframe computers. At the present stage, the systems and aids of domesitic mathematical modeling of technological processes is an integral part of effective functioning of alumina refinery, the specifics of the engineering plan of which makes it difficult or even excludes the possibility of a unified approach to construction of their digital twins and necessitates flexible combining the individual and universal approaches. The functionality of the models is implemented in the Windows environment with the use of SysCAD software, which makes it possible to obtain information about properties of any material flow, parameters of each technological apparatus and to solve a complex of operational and system issues. Until the present time the relevance of profound understanding of the nature of the laws, phenomena and processes occurring in the alumina production systems, as well as building the special-purpose electronic databases. This would allow one to develop and apply relevant physicalchemical model of the plants at which alumina is manufactured not only from bauxites but also from the other types of aluminiferous raw materials. At the same time, further improvement of mathematical tool is associated with the need to improve the efficiency of multithreaded calculations in design of technological systems, which being combined with an access to powerful computing resources creates the conditions for transition to a new level of solving production technological problems, including multiparametric optimization of alumina plants and others.

The work was carried with financial support of the Russian Science Foundation No. 18-19-00577 dated April 26, 2018 on providing the grant for conducting fundamental scientific and exploratory researches.
