Cluster of M polygons to N homogeneus groups

Hi everyone,

I have a region completely covered by M given polygons. Each of them has several attributes.

I need to cluster or group neighbourgh polygons to obtain N, new, bigger ones (N<M).
To group them, I need to make a polygon union and add the values of the attributes of the individual polygons to obtain the attributes of the new polygon.

The point is, that the resulting polygons must have similar attributes values, or as similar as possible.

Can anybody tell me which Spatial Function should I use to do that?
