Implementation of a defuzzification of set of fuzzy labels Java implementation of a defuzzification of set of fuzzy labels according to the COG method: Center of Gravity. This method consists in calculating the center of gravity of each trapezoidal fuzzy set. The trapezoidal set is defined in the FuzzyNumbers file. Given a set of alternatives that are associated to a linguistic fuzzy term (alternativeValues file) a translation to the corresponding numerical COG is made.

(For outputs, see below)
Linguistic label describing the performance of each alternative
The input value should be a valid XMCDA document whose main tag is <alternativesValues>.
It must have the following form:
<alternativesValues>
<alternativeValue>
<alternativeID>
identifier
</alernativeID>
<value>
<label> ... </label>
</value>
</alternativeValue>
[... list of other alternatives with id and label ]
</alternativesValues>
Definition of a fuzzy variable as a list of labels (trapezoidal)
The input value should be a valid XMCDA document whose main tag is <categoriesValues>.
It must have the following form:
<categoriesValue>
<categoryValue>
<values>
<value id="xxx" name="xxxxxxxx">
<fuzzyNumber>
<trapezoidal>
<point1>
<abscissa>[...]</abscissa>
<ordinate>[...]</ordinate>
</point1>
[...]
<point4>
[...]
</point4>
</trapezoidal>
</fuzzyNumber>
</value>
[...]
</values>
</categoryValue>
</categoriesValue>
Numerical score for each alternative according to the input fuzzy label.
The returned value is a XMCDA document whose main tag is <alternativesValues>.
A status message.
The returned value is a XMCDA document whose main tag is <methodMessages>.
