Abstract: The article considers the application of the analytic hierarchy method in the problem of determining the relative value of the energy system sections operability. The process of building a hierarchy is described for the sections of the energy system, which are assessed by the groups of criteria and by the component criteria. There is shown the process of filling in scores and matrices of paired comparisons, as well as calculating the components of priority vectors for each of the hierarchy levels. The analytical expressions are formulated for the synthesis of priorities and determination of the values of the relative risk of inoperability for each of the sections. A diagram is constructed showing the relative risk of inoperability of individual sections of the energy system.

Keywords: decision making, analytic hierarchy system, sections of the energy system, priority vector, matrix of paired comparisons.
