Companies often have to choose the best equipment among alternatives with similar features when making machinery and equipment investment. Making the most appropriate choice among much alternative equipment is a complex decision-making process that requires evaluation of multiple criteria. Multi Criteria Decision Making methods are frequently used in this process. In this study, the plastic injection machine selection process of a company was considered. The importance levels of the criteria and alternatives were determined by using linguistic expressions and the decision-making problem was solved by fuzzy-based MCDM methods. In this study, in addition to the traditional criteria such as cost and technical features, which are frequently used in the current literature, environmental friendliness, safety, and reliability criteria are included. First, the determined criteria were evaluated by a decision-making team consisting of three experts in the field. Then Fuzzy TOPSIS and Fuzzy VIKOR methods were applied for choosing the alternative that best satisfies the selection criteria of decision makers.
