Technique of management of the choice of rational structures of electronic scrap

In the present article ways of the choice of different types of technogenic scrap for providing the enterprise of secondary metallurgy with those structures which processing will give the maximum economic effect are considered, and also makes a contribution to a task of rational environmental management by their utilization. Effectiveness of purchase of consignment of furnace charge is estimated by the modified integrated indicator considering values of function of desirability of the operating influences with use of the weight coefficients reflecting the different importance of private indicators of efficiency and a contribution of each of them to the final decision. Besides, the desirability of the structure of scrap which has come to the market is estimated, respectively, the base price of raw materials is adjusted. For creation of the generalized indicator of efficiency function of desirability of Harrington is used. For the purpose of determination of behavior in the competitive market of purchase the enterprise is offered to use provisions of mathematical game theory. Actions of the enterprise in the competitive market of purchase of raw materials are considered as a game against «nature» where «nature» is a condition of the market. Adjustment of purchase prices is carried out consistently, considering composition of the offered raw materials, financial opportunities of the enterprise, is also shown that it is expedient to the enterprise which isn’t dominating in the market to increase the scrap price incidentally. The scheme of payment of deliveries of electronic scrap for the enterprise of secondary metallurgy using the technological scheme of complex processing of raw materials considering features of structure of scrap, a situation in the market and the change in price for gold is offered. Final payment of the arrived party is made taking into account assessment of estimated revenue after extraction of all valuable components, according to the developed mathematical model. It is shown that increase in efficiency of economic activity of the enterprise is possible due to application of a technique of management of the choice of rational structures of electronic scrap for optimization of the sequence of the arriving compositions of raw materials and increase in efficiency of economic activity.
