Ensuring operational efficiency of mining and metallurgical enterprises on the basis of sustainable development

Purpose. To improve dynamic management of operational efficiency (DMOE) to ensure the sustainable development (SD) of the enterprise in the conditions of challenges. The task of the article is: to investigate external influences on the functioning of mining and metallurgical enterprises (MME); to identify prerequisites for DMOE, directions for improvement of operational efficiency of management tools. Methodology. The method of content analysis made it possible to determine SD of enterprises in the conditions of dynamic challenges as a balanced quasi-sustainable development. The dialectical method was to establish the fact that risks of war also create windows of opportunity for enterprises. The method of critical analysis established the fact that the significant dynamism of challenges determines the dynamism of adaptive management. The method of analysis and synthesis was to propose a systematic and fragmentary approach to implementing measures to improve operational efficiency. The method of mathematical analysis made it possible to propose a transition from using not factors, but their derivatives, for modeling DMOE. Findings. The effects of modern challenges on the functioning MME were studied. Prerequisites for the introduction of dynamic adaptive management of operational efficiency were determined. Areas of improvement of DMOE tools were determined. An approach of operational coordination of operational efficiency with dynamic changes in the internal and external environment is proposed. The management of the operational efficiency of one of the mining enterprises was studied. Originality. The need for DMOE as a tool for sustainable functioning of the enterprise is substantiated. It is proposed to define SD at a significant level and dynamics of changes in external influences as a balanced consistent set of quasi-steady states, which increases the effectiveness of management measures. Practical value. The proposed approaches increase the relevance of the evaluation of DMOE, which increases the effectiveness of management and the possibility of achieving balanced development of MME.
