Integrated Weighted Distance Measure for Single-Valued Neutrosophic Linguistic Sets and Its Application in Supplier Selection

Abstract EN

The purpose of this study is to propose an integrated distance-based methodology for multiple attribute group decision making (MAGDM) within single-valued neutrosophic linguistic (SVNL) environments.

A new SVNL distance measure, namely the SVNL integrated weighted distance (SVNLIWD) measure, is first developed for achieving the aim.

The remarkable feature of the SVNLIWD is that it integrates both merits of ordered weighting and average weighting into aggregating SVNL distances; therefore, it can account for both the importance of aggregated deviations as well as ordered positions.

Thus, it can highlight the decision makers’ subjective risk attitudes and combine the importance of objective decision information.

Some distinctive characteristics and special forms of the presented distance framework are then specifically studied.

Moreover, a MAGDM model on the basis of the proposed SVNLIWD form is formulated.

Finally, an illustrative numerical case regarding selecting low-carbon supplier is used to test the performance of the designed method.
