Abstract

Theaimofthispaperistointroduceanovelapproachforassessingtheriskstothecontinuous availability of cost-effective energy sources by proposing a Multi-Criteria Decision Making method that considers the interdependence between the indicators utilised in the measurement process. The paper focuses on Spain and Portugal into the EU energy market and investigates the consequences of their particular conditions. To account for the significance of each criterion and its subsets, the Choquet Integral is integrated into the analysis. The f indings demonstrate the effectiveness of this approach in incorporating expert knowledge into Energy Security evaluations, which can be utilised to develop enhancement policies.
