摘要：The paper presents the system of models for the fuel and energy complex functioning used to determine the critically important facilities, built on the basis of the fuel and energy complex territorial production model of the . A formalized representation of the model is given, a three-stage scheme for working with it is described. For the selection of the fuel and energy complex critically important facilities , the most important and accompanying model indicators are highlighted, an integral indicator of the industry elements criticality is proposed. The results of testing the developed models are presented (illustrative example).
