Abstract

The aim of this study was to extend the MULTIMOORA- 2T method for group multi-criteria decision making under linguistic environment. Whereas the previously offered MULITMOORA-2T is aimed at dealing with quantitative assessments, the new method MULTIMOORA-2T-G tackles qualitative ones. More specifically, expert evaluations expressed in 2-tuples were summarized aggregated by employing 2-tuple ordered weighted averaging (TOWA) operator and thus a new method, namely MULTIMOORA-2T-G, was offered. The method enables to summarize expert assessments when information about their significance is completely unknown. The numerical example successfully exhibited the possibilities for application of the MULTIMOORA-2T-G method. In this particular case the committee consisting of five experts ranked the potential suppliers by applying the new method with respect to different criteria identifying the potential of the considered suppliers. Such decision making method enables a company to develop an appropriate procurement policy under vague conditions.
