It is important to work with qualified human resources, especially in today's world, where the importance of knowledge and having the right information is increasing day by day. Having the right human resources is an important tool in increasing the competitiveness of businesses. The selection phase of the right candidate is one of the difficult steps of the process. To choose the right candidate among alternative candidates, it may be necessary to find the candidate who meets many criteria in the best way. It is very useful to use Multi Criteria Decision Making techniques in such problems where many alternatives and multiple criteria should be evaluated, in terms of ensuring that all criteria can be included in the evaluation phase. In this study, the problem of choosing a human resources manager of a manufacturing company operating in Sakarya is discussed. The DEMATEL and VIKOR methods, which are among the Multi Criteria Decision Making techniques, have been studied fuzzy in order to take into account heuristic evaluations. Six criteria and seven alternatives were determined for the problem.
