Intuitionistic fuzzy theory is an excellent tool to represent uncertainty and vagueness in fuzzy multi criteria decision making problems. When intuitionistic fuzzy numbers are used to express fuzzy information, they need to compare with each other to indicate the relative importance or priority. This paper reviews an existed method of ranking two intuitionistic fuzzy numbers, and further defines another...
The effective management of uncertainty is one of the most fundamental problems in decision making. Currently, most decision models rely on point estimates for input parameters, although the uncertainty surrounding these values is well-recognized. This study reviewed the problems that are commonly involved in computational problems involving expert's epistemic uncertainty. In order to transfer the...
