Purpose This paper proposes a new multi-criteria decision-making method, called the vital-immaterial-mediocre method (VIMM), to determine weight of multiple conflicting and subjective criteria in problem. Design/methodology/approach The novel utilizes pairwise comparisons, vector-based procedures scoring approach weights criteria. VIMM compares alternatives by three crucial components, namely v...

Crisp values are insufficient to model real-life situations and imprecise ideas frequently represented in multicriteria decision aid analysis. In fact, it is difficult treat the evaluation criteria precisely fix exact preferences rating. The triangular intuitionistic fuzzy numbers succeeded this kind of ambiguity a great deal research than other forms representation functions. field sorting iss...
