MCDM methods can be used in many areas when decision making process is weighed on the basis of many influential parameters. Results of this study show that MCDM methods, such as TOPSIS and VIKOR, can also be applied for flotation machine selection.
Five flotation machines were evaluated by three experts using ten criteria divided in three groups: constructional, economical and technical and the results of their evaluation were the basis for application of VIKOR and TOPSIS methods. In the first step of the selection the results obtained with these two MCDM methods were different: machine A4 was seen as the best alternative by TOPSIS, while VIKOR recognized machine A3 as the best alternative. In order to determine which of these two machines was really the most appropriate one, the machines were re-evaluated based only on two groups of criteria: constructional and economical. The results of the additional evaluation showed that the machine A4 was the best ranked by both methods.
