Data Mining Techniques GeeksforGeeks
In general, the usage of fuzzy logic in rulebased systems involves the following: Attribute values are changed to fuzzy values. For a given new data set /example, more than one fuzzy rule may apply. Every applicable rule contributes a vote for membership in the categories. Typically, the truth values for each projected category are summed. 3.

Underground mining method selection by decision making tools
In this paper, a computer program (UMMS) based on the AHP and the Yager''s method for underground mining method selection was developed. The UMMS provides two different AHP models so that the decision makers can analyze the selection problem based on either only main criteria or main criteria with their subcriteria.

DecisionMaking in a Fuzzy Environment | Management Science INFORMS
By decisionmaking in a fuzzy environment is meant a decision process in which the goals and/or the constraints, but not necessarily the system under control, are fuzzy in nature. This means that the goals and/or the constraints constitute classes of alternatives whose boundaries are not sharply defined. An example of a fuzzy constraint is ...
