Based on the FIS implementation in this paper, we
conclude the following. First, managers in enterprise know
how important KM was; but it was very difficult to
implement it successfully, especially how to choose the

filled with multiple conflicting criteria as well as incomplete
information. Third, applying the fuzzy inference system
Mamdani is an important part of the intelligent decision
making because of its ability to deal with the uncertainty

through a graphical user interface (GUI) the interaction
between a user and fuzzy logic system make KMT
evaluation is simply, fast and efficient
