Analysis of energy efficiency of territories based on hybrid cognitive maps hierarchy

Abstract

Unsolved problem of the situation analysis in the territorial energy saving sphere providing incompleteness of source data and ambiguity of their interpretation causes the actuality of the research. The objective of the paper is the development of cognitive approach to the energy efficiency state analysis for different territories that allows not only estimating the level of energy efficiency but also analyzing the causes of the current situation and identifying the key areas of energy saving policy. The authors use fuzzy cognitive cards' building methods, fuzzy estimation methods and fuzzy production inference, clustering methods. Results: hybrid cognitive card structure is introduced; cognitive cards hierarchy building is described; case-approach to cognitive cards analysis is proposed; factor assessment methods for different situations are considered. Conclusion. The use of hierarchical hybrid cognitive cards provides the following advantages: the possibility of detailed review of separate subsystems, the increase of validity at indicator choice, the combination of different methods of factor assessment, the analysis of territorial external features. The outcomes of analysis can be represented as a reason tree that displays causal chains between states of different factors.
