Özet:

This study aims to evaluate the multi-period financial performance of crude iron and steel-producing enterprises in Türkiye using the extended grey MULTIMOORA method. The Grey MULTIMOORA method, extended with the proposed new grey full multiplicative form, is used to solve multi-period and multi-criteria decision problems without uncertainty, different from its original intended use in this paper. In aggregating the ranking results obtained from three different approaches, the Copeland method is proposed instead of the dominance method used by MULTIMOORA. The method was applied to analyze the multi-year financial performance of crude iron and steel-producing enterprises in the BIST Basic Metal Industry Index. As a result of the analyses, it was concluded that the results of the proposed method involve the results of more than one alternative method and that the technique alone provides the opportunity to examine the decision problem and solution results in a multidimensional and more detailed manner.
