Abstract

In this paper, we define a new function, the generalized linguistic weighted OWA (GLWOWA) operator, to aggregate linguistic information. The proposed operator combines the advantages of the linguistic weighted arithmetic averaging (LWAA) operator and the extended OWA (EOWA) operator, and improves the linguistic weighted OWA (LWOWA) operator. We study some of its properties and compare it with the linguistic hybrid arithmetic averaging (LHAA) operator. Based on the LWAA operator and the GLWOWA operator, we develop an approach to multi-attribute group decision making with linguistic information.
