Site Selection Module
Within Sites, the portfolio selection software is called the Site Selection Module (SSM). It was originally written by Ian Ball and Hugh Possingham of the University of Adelaide in Australia as a stand-alone Windows-based program. SSM:
provides 2 heuristic procedures--simulated annealing and “greedy”
allows the analyst to control the spatial configuration of the conservation portfolio
facilitates exploration of alternative goals and assumptions
allows planning units to be required or excluded in a portfolio
compares the portfolio to the distribution of a given conservation element
