Anderson (1981) also developed a multiple-objective, multiple-publics method for evaluating alternatives in water resources planning called the cascaded tradeoffs method. This method prepares an overall ranking of planning alternatives on the basis of public values. The key feature of the method is that it provides for tradeoffs across both issue dimensions (decision factors) and publics. Finally in terms of commensuration approaches, Brown and Valenti (1983) developed the Multiattribute Tradeoff System (MATS). MATS is a computer program that helps planners evaluate multiattribute alternatives to determine each alternative's relative worth or desirability. MATS leads the user through a series of questions (a tradeoff analysis) which focuses on the relative importance of various characteristics of the alternatives. The program documents the judgments which lead to developing a policy for evaluating alternatives. Importance weighting in MATS involves use of the unranked paired comparison technique, described earlier. Impact scaling is based on functional curves, also described earlier.
