International Journal of Business and Systems Research, 9(4), 355–374.175120181751200Xhttp://hdl.handle.net/11268/4370Application of MCDM methods in different fields of knowledge is increasing and new techniques are invented to help decision experts achieving optimised solution and getting reliable and facilitated route to final decision. Multi-objective optimisation on the basis of ratio analysis (MOORA) is a recent and novel tool invented and employed in many scientific projects. In other side, in every decision environment, there are massive information and undetermined situations which affect decision process and evidently its outcomes. Therefore, to improve decision preciseness and to overcome vagueness in uncertain environments, fuzzy theory and newly intuitionistic fuzzy approach try to get more reliable solutions. In this paper, a new version of intuitionistic fuzzy MOORA technique is proposed with triangular fuzzy numbers in a group decision making situation. Ultimately, a case of project selection problem is supposed to validate the applicability of the proposed approach.spaMOORAMCDMjournal article10.1504/IJBSR.2015.072584restricted accessDecisión, Toma deToma de decisiones
