| Description | To increase the efficiency of energy use at non-ferrous metallurgy enterprises, an integrated approach is required to assess energy consumption. Therefore, the urgent issue is the development of a methodology that most fully reflects the specifics of the non-ferrous metals production, based on the methods of expert evaluations, cluster and rank analysis, which allows us to evaluate and implement energy management. The objectives of the research in this work are: development of a methodology for expert assessments, which allows to assess the influence degree of technological production indicators of the hard alloys on the consumption of electricity; conducting a statistical analysis of expert assessments for a number of null hypotheses; development of a methodology for cluster analysis of the main indicators of technocenosis, which allows one to build histograms and mathematical models of the distribution of the sums of ranks of expert assessments for all castes of rank distribution. The formation of clusters and the construction of a dendrogram of weakly correlated indicators among themselves, the influence of which for individual castes on the consumption of electric energy is quantified by the values of the weighted average fuzzy numbers. Cluster analysis made it possible to clarify for the non-ferrous metallurgy enterprise significant weakly correlated indicators that have the greatest impact on electricity consumption. An analysis of significant weakly correlated indicators showed that they are all divided into two main groups on the basis of their possible use to obtain the regression equation.
