Decision-makers face many challenging issues during their careers. To improve the accuracy of decisions they made, Multi-criteria Decision Making (MCDM) plays an important role. One of the widely used MCDM methods is the Analytical hierarchy process (AHP). There are many reasons (advantages) behind the popularity of the AHP. For instance, AHP is the only MCDM method that can measure the consistency of the judgments of the experts. However, pairwise comparison is performed on a 1-9 scale in AHP methods, which in turn may cause that decision-makers can not reflect their judgments very effectively. To eliminate this drawback and to further strengthen the AHP tool, the fuzzy AHP method was introduced. Currently, various computer programs, which can perform MCDM methods, were developed such as Expert Choice and Super decision. However, any software has not been developed for the fuzzy AHP method. This reduces the exploitation of the benefits of the fuzzy AHP method by the professionals since they usually have little time for learning new methods. Thus, this study aims to develop a script in the Matlab environment that can perform fuzzy AHP analysis. The computational accuracy of the tool was tested by using the data of Işık and Aladağ (2017). The results showed that the tool is reliable to use in the decision-making process.
