-<h2>DESCRIPTION</h2>
-
-<em>r.mcda.fuzzy</em> is the implementation of the FUZZY multicriteria
-algorithm proposed by Yager R., in GRASS GIS environment. It is one of the
-available tools in the r.mcda suite. It requires as an input the list of
-raster representing the criteria to be assessed in the multicriteria
-evaluation and the vector of linguistic modifiers to be assigned. Every
-single cell of the GRASS region is considered as one of the possible
-alternatives to evaluate and it is described with the value assumed for
-the same cell by the raster used as criteria. It is possible to get three
-different output files as the result of the intersection operator, the
-union operator and the ordered weighted averaging (OWA) operator.
-
-
-<h2>NOTES</h2>
-The module does not standardize the raster-criteria. Therefore, they must
-be prepared before by using, for example, r.mapcalc. The linguistic
-modifiers vector is always normalized so that the sum of the weights is 1.
