The methodological and informational principles of decision support systems (DSS) for controlling the charging mode and the blow distribution over the blast furnace tuyeres are presented. The creation of the presented DSS’s consists of the following stages: development of an information modeling module for the distribution of charge materials when charging blast furnaces with a bell-less or bell-type charging device; use of information from modern automated control tools with the establishment of statistical dependencies of this information with blast furnace smelting indicators; creation of a representative database containing various blast furnace operating modes with the corresponding technical and economic indicators of blast furnace smelting, charging mode parameters and information from control tools; use of direct and iterative optimization methods; development of methods and criteria that allow ensuring synergistic interaction of the DSS’s functioning. An important stage of DSS’s development is the testing of their individual components and recommendations for blast furnace smelting management in real production conditions.
