摘要
The subject invention comprises methods for developing a decision hierarchy and including data as well as judgments in the evaluation of alternatives. Using a preferred embodiment of the subject invention, data for alternatives with respect to covering objectives in a decision hierarchy can be mapped into ratio scale preferences using linear increasing or decreasing functions, non-linear concave or convex increasing or decreasing functions, in conjunction with either-or interval step function scales, verbal intensity rating scales, or directly applied value scores. Upper and lower bounds can also be specified over which these functions are defined. Qualitative data, such as ratings or step scale intervals, can be mapped into a preference scale by making pair-wise comparisons to assess the ratings' intensities. Data can also applied in two other contexts: (1) as a screen to eliminate alternatives that do not satisfy one or more conditions which are defined as musts by the user; and (2) to assign and derive value scores for their corresponding covering objectives. User priorities that were captured by delivering comparisons between objectives are brought together with the data by synthesizing it with respect to all covering objectives and their representative value scores for each alternative. The final result is either a set of alternatives ranked by their total value score, which can be used for allocations or optimizations, or a single top scoring alternative if the goal is to select the best alternative—the remainder of the alternatives are ranked with respect to their difference from the top performer.
