Selecting Risk Modelling Approaches with the Analytic Hierarchy Process : the treatment of hidric basins in the State of São Paulo, Brazil

Abstract

The approach of modelling expected values with multiple criteria should be considered any time AHP models, decision trees, or a decision tables are being used. While with AHP models the introduction of scenario nodes can enrich the existing multi-criteria treatment, the introduction of multi-criteria to decision trees or decision tables can enrich the existing scenarios. The analytic hierarchy process (AHP) is uniquely positioned to help model situations of uncertainty and risk since it is capable of deriving scales where measures ordinarily do not exist. By allowing subjective probabilities to be elicited from knowledgeable people, we can mo
