These two decision support programs are early implementations of techniques based on the propagation of imprecise preference statements in hierarchical weighting. In particular, INPRE analyzes interval judgments of relative importance in the analytic hierarchy process (AHP) while ComPAIRS works with similar statements in value tree analysis. The underlying methodology of these programs is described in the references below.
