At present, the question of the competitiveness of the production of special equipment continues to be relevant, which in turn determines the need for a thorough justification of the choice of specialized equipment used, including metal-cutting machines. At the same time, the current level of industrial development and the constant improvement of special equipment products leads to the fact that the range of machined parts is constantly increasing, which leads to regular technical re-equipment of the production of special equipment elements. Technical re-equipment, in turn, entails the need to develop and use the most competitive metalworking equipment (MO) both in the long and short term. Increasing the competitiveness of metal-cutting machines is achieved, in particular, by creating and selecting economically justified size ranges of metal-cutting machines and equipment that fully meets the current and future needs of the consumer. Many logistics tasks require information about the technical and economic functions of optimization objects. The lack of publications on the detailed structure of these functions makes it difficult to apply mathematical methods in logistics. The authors proposed a detailed structure of technical and economic functions with an example of their application to optimize the purchase of metalworking equipment by an enterprise. The purpose of the study: to build a model of the purchase of machine tools and equipment that is adequate to real conditions.
