“…The classical TOPSIS method (see Jia et al, 2012;Ahmadi et al, 2014;Bilbao-Terol et al, 2014;Mulliner et al, 2016) and its extensions, such as interval TOPSIS (see Giove, 2002;Jahanshahloo et al, 2006;Dymova et al, 2013), fuzzy TOPSIS (see Awasthi et al, 2011;Awasthi & Chauhan, 2012;Bao et al, 2012;Ye & Li, 2014;Lee et al, 2014;Kusi-Sarpong et al, 2015;Şengül et al, 2015), interval-valued fuzzy TOPSIS (see Chen & Tsao, 2008;Ashtiani et al, 2009;Mokhtarian, 2015;Zhang & Xu, 2015), and grey TOPSIS (see Chen & Tzeng, 2004;Oztaysi, 2014;Siozinyte et al, 2014;Jiang et al, 2015), have demonstrated their capabilities and potentials in dealing with MCDM problems of various fi elds.…”
