Blast furnace procedure is a set of a large number of physical and chemical, thermal and mechanical processes, which do not take place separately, but are rather in certain mutual relation. The flow and the efficiency of the blast furnace process can be significantly affected by the quality of the input raw materials, which can be evaluated using a number of different criteria. That is why the selection and evaluation of the suppliers of strategic resources play very important role. Metallurgical enterprises must often compare and evaluate dozens of offers and they must monitor a number of regular and irregular suppliers. The evaluation of the suppliers of raw materials for metallurgical production can be realized in different ways. Most of the methods are based on monitoring the pre-defined criteria. During the decision-making itself, it is possible to consider a number of criteria related to the offered raw materials and services, in particular their quality, price and the contract terms. In practice, however, the number of the monitored criteria is usually limited to those that have certain weight in terms of the specific technological conditions of the company. Their selection must naturally be considered very carefully. The definition of importance of the individual criteria represents a key aspect in the evaluation. This will always be subjective to some extent. To define the weights of the individual criteria, it is possible to use the methods that reduce the subjective nature of the decision-making process. The article deals with the analysis of current approaches in the evaluation of suppliers in the area of metallurgical production. At the same time, it analyzes the possible utilization of the methods of distance from a hypothetical option and the methods of pair comparisons in the evaluation of the suppliers of input raw materials for metallurgical production.
