Abstract

In this study two way multi-criteria decision-making approaches are used to select and rank the best phase change material for energy storage from a given set of alternatives. Firstly, multi-objective optimization on the basis of ratio analysis (MOORA) plus full multiplicative form (MULTIMOORA) is applied to select the best candidate material. Result shows that 88Al:12Si is the best material considering the selection strategy. Again, multi-objective optimization on the basis of simple ratio analysis (MOOSRA) is used to measure the performance of the candidate material. Study also reveals that Aluminium, commercial purity, 1-0 wrought is the optimum material for energy storage described by MOOSRA method.
