The problems of selection of optimal mathematical model of energy consumption at industrial enterprises

Abstract

The determination of so called “standards” of energy consumption is one of the most essential stages of creation and efficient operation of energy consumption control systems that are widely used in foreign practice and are known in Ukraine as energy consumption control and planning systems. This “standard”, in general, is a more or less complex mathematical model of fuel or energy consumption by certain technological objects (plant, unit, and processing line) depending on key criteria essentially affecting energy use of such object. It is proposed to use multi-criteria optimization method in order to obtain the best mathematical model. The situations, when one mathematical model is more accurate according to generalized additive criterion, while the other one is accurate according to multiplicative criterion, arise in the process of selection of optimal mathematical model, applying the criteria of equal significance. In this case, it does not ensure unique determination of optimal energy consumption mathematical model. It is proposed to introduce a decisive generalized morphological criterion for “n” number of criterion cases in order to distinguish necessary model, concerning the precision of its description of incoming data for industrial enterprises using different types of resources.
