Fuzzy logic allows decision making with estimated values under incomplete or uncertain information [3].
MCDM is a modelling and methodological tool for dealing with complex engineering problems.
Decision makers face many problems with incomplete and vague information in MCDM problems since
the characteristics of these problems often require this kind of information.
Fuzzy set approaches are suitable to use when the modelling of human knowledge is necessary and when human evaluations are needed.
Fuzzy set theory is recognized as an important problem modelling and solution technique.
