Modeling assessment of power consumption efficiency at iron ore mining enterprises

Today's world requires controlling the process of power consumption and supply. The control system should respond proactively preventively to external disturbances. Among such disturbances for iron ore mining enterprises, most significant are changes in technology operating modes stationary receivers, taking into account costs. General methodological approaches forming models that relate indices a given volume mass mined investigated. Methods formalizing components enterprises engaged underground raw materials under study. building mathematical model optimal efficiency studied. synthesized makes it possible determine mode operation required mine amount mass, while minimizing cost consumption. A target function is built considering consumed by an enterprise. Minimization formed as task reducing functional terms active at certain period time. proposed solution limited condition time dependent, i.e. piecewise-constant function. As result, with two values. qualitative graphical representation considered dependence presented. Based on visual analysis, analytical according day formed.
