“…For a comparative evaluation of processes functioning, the authors traditionally introduce a number of estimated indicators and indicators of quality control, each of which determines one or another side of these processes [11]. If applying of indicators is related to control, then it is necessary to distinguish the category of indicators directly related to cybernetics [12,13].…”

Research connected with studying of efficiency assessment possibility of system operation simple model using its general model parameters and establishing of operation general model objects as efficiency formula`s formal signs is presented in the article. To conduct research, model of controlled system was created, structure of which is implemented as software product. Peculiarity of this model is possibility of carrying out experimental study, as result of which it is possible to detect changes in parameters of number of system operations under different control regimes. As result of research, it was established that it is impossible to make comparative assessment between operations, which conducted in different control regimes, applying quantitative characteristics of input and output operational process parameters. During creation of converting class system model structure, concept of operation reduction to its simple general model has been used. Model of program designer provides integration of cost parameters of input and output products by means of which, opportunity for efficiency determination of operations, functioning at different control modes is investigated. Analysis of operational process estimation results has shown that operation general model objects are formal signs of operations efficiency formula. Different modes of optimum control to which have pointed extrema of several indicators have revealed absence problem systemically reasonable verification method of applied estimated indicators regarding their use as optimization criterion. Practical importance of this research is that using presented program designer of controlled system and cybernetic approach allow apply results of research on all types of controlled systems. It promotes the optimization issue solution in finding of optimum mode of executive systems functioning and obtaining maximum economic effect of enterprise.

“…The copper loss in the smelting slag is generally considered in the literature (Mitevska 2000;Jalkanen, Vehviläinen, and Poijärvi 2003;Zivkovic et al 2009Zivkovic et al , 2010Mihajlović et al 2011), while data on the other elements' distribution, between the slag and matte, are rare. In this paper, we present the results of the research on the effect of slag basicity and composition on the coefficient of distribution of certain metals between the slag and the matte.…”

This paper presents the results of investigation of the effect of slag composition and the slag basicity, in the process of smelting of sulfide copper concentrate, on the distribution coefficient (L S=M Me ) for the following elements: Cu, Bi, Co, Au, Ag, Zn, Pb, Ni, As, Sb, Se, and Te. The research was conducted under the industrial operating conditions of the copper smelter in Bor, Serbia. High values for the coefficient of determination (R 2 > 0.6) for the L S=M Me dependence on the slag composition were obtained, which presents a high degree of fitting.In the case of the dependence of L S=M Me on the slag basicity, obtained R 2 values were much lower, due to the much smaller statistical sample.
