Abstract

The article presents the results of solving of multicriteria problems optimization for determine the structure of charge materials for electric arc furnace using three methods: a method of concessions, a method of convolution and a method of restrictions. The feature of this task is the availability of empirical system, which includes the goal function, the system of constraints and the sequence of two interrelated tasks. For solving this task was developed a software, which allows to perform automatic data input, to determine the order of solving tasks, to assign the concessions and weighting coefficients.
