PROBLEM STATEMENT FOR MANAGING FUEL AND ENERGY COMPLEX FACILITIES AND ITS MATHEMATICAL DESCRIPTION

Currently, sustainable development of enterprises places great emphasis on analysing energy and resource conservation issues, as well as energy management. The paper identifies common traits of processes relevant to energy efficiency problems; lists tasks and tools of energy management; proposes an enterprise structure as an energy-technological system; outlines stages of developing a managing system of fuel and energy complex facilities with the aid of the IDEF0 functional modelling methodology. The authors analyse methods of energy-technological system control; propose a package of measures for enhancing energy efficiency at enterprises; suggest improved models for raw material composition and product quality indicators. The work enumerates advanced methods and models for predicting thermal and electrical energy consumption, as well as product output; provides steps of a methodology for refining oil preparation and primary processing management based on orthogonal central composite design and extreme regulation. For installation reconstruction, the authors recommend the variable-structure Fishburn criterion. The derived results can be applied when constructing fuel and energy complex facility management systems to address energy and resource conservation challenges.
