Using the Triangular Fuzzy Numbers for the Verification of a Chosen Decision

Fuzzy numbers play a fundamental role in fuzzy mathematics, analogous to the role played by the ordinary numbers in classical mathematics. In this work we use the Triangular Fuzzy Numbers for the verification of a chosen decision and we give an example illustrating our results in practice. In order to check the creditability of our new fuzzy method, the outcomes of its application are compared in our example with the corresponding outcomes of two traditional methods, the calculation of the mean values and the use of the GPA index.
