I mentioned in a recent post that our latest update to GeoPlanner for ArcGIS includes the ability to create web-based weighted overlay services using your data.These services allow you to perform suitability modeling so you can understand risks and opportunities in an area based on your criteria. You can make these services available to ArcGIS Online groups, organizations, or the public.
This functionality supersedes the Landscape Modeler.
Check out this doc to help you get started.
Download this toolbox to help you setup your service.
