Sustainability Analysis in Electrical Energy Companies by Similarity Technique to Ideal Solution

Abstract

Considering the need to assess the corporate sustainability, get a compromised solution for multi-objective functions taking into account several criteria, according to their economic, environmental and social performance, usually is an important topic and a really tough problem for decision authorities. The paper presents a novel model for solving decision making problems in the evaluation of corporate sustainability. The proposal was applied in the analysis of sustainability indicators of energy sector in Brazil. The principle of the technique of preference ordering by similarity to ideal solution is based on the premise that the solution should be chosen as close as possible the positive ideal solution and as far as possible the negative ideal solution. The model applied proved to be robust for the evaluation and ranking of companies with respect to aspects of sustainability observed.
