Problem-oriented modeling in industrial technology: The steel industry

Abstract

The development of up-to-date industrial technology and improving efficiency can be achieved by operational control and management and by research and design. These three problems and the corresponding subproblems can be formulated, investigated, and solved on the basis of problem-oriented mathematical models. The general approach to the development of the problem-oriented models has several particular features that depend on the problems to be solved—knowledge and data about the systems to be modeled, demand for model accuracy, type of model solution (off-line or on-line), computer type, and so on. The results of implementing problem-oriented models to improve the efficiency of industrial technology is considered for the case of steelmaking in basic oxygen furnaces (BOF), which is the most widely used technology in the world. The problems that were formulated, the approaches to the development of the mathematical models, and the processes that occur in BOF technology are typical for other different kinds of industrial technology, such as chemicals, the cement industry, atomic reactors, and the glass industry.
