Algorithmization of the automated determination of the optimal composition of the components of the metal charge according to the given initial conditions (chemical composition of the alloy and components of the charge, bum-out loss of the alloy elements, the content of return, scrap and waste) is carried out, which allows to perform operational adjustment of the component composition of the charge directly in production conditions under the constantly changing assortment of charge materials. Functional capabilities of the software include: calculation of the component composition of the charge when smelting multi-component alloys using an unlimited set of initial components; setting the percentage or mass content of the charge components and the bum-out loss of chemical elements during smelting; determination of the optimal composition of charge on the basis of the simplex method to minimize the target function of the cost of charge under the given initial conditions; imposition of additional restrictions on the cost of metal components. Validation of the program was carried out on the example of selection of component composition of charge for smelting aluminum alloys for the construction industry.
