SPECIFIC FEATURES OF VECTOR OPTIMIZATION METHODS FOR SELECTING THE OPTIMAL COMPOSITION OF BLAST FURNACE CHARGE
Keywords:vector optimization methods, multi-component blast furnace charge, technological constraints, optimality criteria, model
Technological and mathematical formulation of the problem of optimizing the composition of multicomponent blast furnace charge, which will ensure the melting of cast iron of the required composition and the given technical and economic indicators of the melting is formulated. The features of the developed algorithm for solving the problem of multicriteria conditional nonlinear optimization with the use of modified simplex methods (Box, Nedler - Mead) are outlined. As a result, an optimal compromise solution in a given area of constraints is found, taking into account a special class of technological constraints, which makes it possible to form scientifically valid recommendations for choosing a rational composition of charge materials in modern conditions of blast furnace production.
