“…In reality, the decision-maker is sometimes unable or unwilling to provide his/her opinions over some alternatives due to insufficient information or limited expertise, especially in face of a large number of criteria or alternatives. In this situation, an incomplete comparison matrix is resulted (Alonso et al, , 2010Chiclana et al, 2008Chiclana et al, , 2009aFedrizzi & Giove , 2007;Gong, 2008;Herrera-Viedma et al, 2007;Liu, Zhang, & Wang, 2012;Liu, Pan, Xu, & Yu , 2012;Xu, 2004Xu, , 2012Xu, Li, & Wang, 2014). MCDM with incomplete comparison matrices have been receiving increasing attention and many different methods have been developed to estimate missing or unknown values for incomplete additive reciprocal comparison matrices (Alonso et al, , 2010Chiclana et al, 2009a;Gong, 2008;Herrera-Viedma et al, 2007;Liu, Pan, Xu, & Yu , 2012;Xu, 2004).…”
