> MCELite takes raster files representing decision criteria and analyzes
> them using three types of multi-criteria evaluation (MCE): Boolean
> overlay, weighted linear combination (WLC) or ordered weighted
> averaging (OWA). It also does sensitivity analysis of the results of
> an analysis. It hasn't been extensively tested, so it is marked as
> experimental, but it does run on Windows, OS X and Linux. The package
> includes documentation and soem sample data data sets and
> configuration files (it reads configuration files in addition to
> having interactive input).

> Because I wrote it for a study project, I didn't use any existing code
> (it turns out it wouldn't have been a problem, but I wanted to be
> safe) and I rolled my own Raster object to do the overlay instead of
> using rastercalc or something like that. I can still rewrite the back
> end, but it would be a lot of work.

> The big thing missing from the tool is any kind of fuzzy set
> membership analysis. I couldn't find any plugins for QGIS, so you need
> to create the input rasters with another tool, if you want to do any
> kind of interesting analysis.

> Anyway, feel free to try it out, and let me know when it breaks. I am
> sure it still has tons of bugs.
