Ranking the saw ability of ornamental and building stones using different MCDM methods

Stone cutting has got an important role and place in the development of stone technology as the first and most important engineering process of stone production. the selection of proper stone with high sawability is very impressive on the quality and time and energy consumption. therefore,deciding on the selection of stone with several characteristics,often opposing to each other,is difficult and complicated. this paper studies the ranking of building and decorative sawable stones with respect to four physical and mechanical criteria using eight multi-criteria decision-making (mcdm) techniques. for the study,12 different kinds of building and decorative stones are examined,seven of which are carbonated and five of which are granite stones. in phase i of the proposed methodology,six of the considered mcdm techniques are used to rank the stones,where the results indicate different rankings but with high spearman ranking correlation coefficients. in the subsequent phase ii,two other mcdm methods are used to provide a coherent definitive ranking. the results showed that these two methods lead to identical coherent ranking.
