Comparison of Different Multicriteria Decision-Making Methodologies for Sustainability Decision Making

The objective of this chapter is to compare different weighting methodologies and different multicriteria decision-making methodologies for sustainability decision making. Four weighting methodologies and four multicriteria decision-making methodologies have been compared in this chapter; the weighting methodologies comprise two objective methodologies (entropy method and ideal point method) and two subjective methodologies (analytic hierarchy process and Delphi method), the multicriteria decision-making methodologies consist of four options, including technique for order of preference by similarity to ideal solution, data envelopment analysis, preference ranking organization method for enrichment evaluation, and principal component analysis. The proposed weighting methodologies and multicriteria decision-making methodologies have been compared by applying them on sustainability decision making among five energy scenarios.
