Lysenko V. Modelling and information support of decision-making concerning economic development of ore dressing combines on the basis of an estimation of rational use the minerals

The ore mining and processing enterprises production activity. Creation of economic-mathematical model of productive capacity of ore mining and processing enterprises, development of the methods of produced ore volume evaluation as the mean of ore production process control, reduction of losses in effective component of the ore mining and processing enterprises, creation of the decision making support system for production process management, approbation and examination of the developed methods, models and algorithms adequacy. Methods of analysis, synthesis, analogies, optimization, interpolation, multiple regression, linear algebra, analytic geometry, simulation, statistical methods, theory of algorithms. The model of the ore mining and processing enterprises productive capacity optimization is created with ecological costs on ore extraction consideration. The new method of the produced ore volume evaluation "The Convex Polyhedron", that gives the maximum precise evaluation of the volume of solid withspatial coordinates of the upper and lower profile is proved and developed.The universal method "The Convex Polyhedron" as the mean of ore production process control for the ore mining and processing enterprises. The production activity of the ore mining and processing enterprises, education.
