Belkina I. Modeling of dependence of economic indicators of mining and processing enterprise productive activity on the ore supply arrangements

The urgent issue of economic efficiency increase of productive activity of mining and processing enterprises with open-cast iron ore mining is addressed in this thesis work. The scientific statements of the work are based on defining new relations between concentrate production, revenue, costs, profit of the enterprise and ore supply dynamic and qualitative parameters. Existence of the relations is proved by methods of economic and mathematical modeling. The method for determination of ore supply arrangements optimization for enterprises in operation and under construction is suggested. On the basis of the suggested method, managerial and economic guidelines on the optimal parameters maintenance are justified and provided. Operational recommendations on the providing of labor discipline control for workers of the mining-transport complex are given, as well as suggestions for the organization of their shift work.
