Abstract

The goal of the article is finding out the nature of influence of duration and period of ore supply upon the income and profit of the enterprise from sales of concentrate. Availability of influence of dynamic parameters of ore supply upon main economic results of activity is determined with the help of methods of economic and mathematical modelling and identification of the nature of this influence with the help of the method of graphical analysis. The article provides economic and mathematical models of influence of dynamic parameters of ore supply upon the volume of concentrate production with consideration of statistical dynamics of occasional process of ore supply. For the first time ever it reveals connection between indicators of income and profit and dynamic parameters of ore supply, which unlike accounting ore processing volumes only allows improvement of relevant economic indicators of activity of the ore mining and processing enterprise by means of managing factors of formation of operation of the mining transportation complex. The article shows that economic results of activity of the enterprise nonlinearly depend on duration and period of ore supply. The said dependencies are obtained for conditions of availability of correlation of quality of ore of successive supplies. The proposed models and revealed dependence allow organisation of operation of the mining transportation complex from the position of ensuring economic efficiency of functioning of the whole ore mining and processing enterprise. The established dependencies should be taken into account when organising operation of the mining transportation complex or when realising organisational and technological solutions that influence periodicity and duration of ore supplies from the trans-shipping storehouse to the processing facility.
