I'm looking for open source tools for location allocation modelling (eg planning public health facilities). Preferably in a GIS environment. I know GRASS somewhat, but doesn't seem to take account of demand.

I don't know if SAGA or Sextante have something?

Is this similar to creating districts or territories, similar to they way you would create territories for a salesman? – jvangeld May 3 '11 at 19:02
Could you do the analysis in a software using a Cartesian system, and then just display the results? QGIS would be one free way of showing the results. – djq May 3 '11 at 21:07
Did you check GRASS 7? There are new* modules available. – markusN May 3 '11 at 23:31

You could try Flowmap. It is specially designed to analyse flow patterns.

You can find it here:
