Improved CODAS Method under Picture 2-Tuple Linguistic Environment and Its Application for a Green Supplier Selection

Abstract

In this paper, the CODAS (Combinative Distance-based Assessment) is utilized to address some MAGDM issues by using picture 2-Tuple linguistic numbers (P2TLNs). At first, some essential concepts of picture 2-Tuple linguistic sets (P2TLSs) are briefly reviewed. Then, the CODAS method with P2TLNs is constructed and all calculating procedures are simply depicted. Eventually, an empirical application of green supplier selection has been offered to demonstrate this novel method and some comparative analysis between the CODAS method with P2TLNs and several methods are also made to confirm the merits of the developed method.
