Determining Preference Weights
This section discusses a procedure for determining the preference weights. Preference weights are weighting factors that a decision maker applies to each of the evaluation measures to indicate the relative importance of each of the evaluation measures. The weights are like probabilities in that they are numbers between zero and one and the sum of the preference weights across all of the evaluation measures must equal one.15
One way to think about the preference weights is to recall a property of single-dimensional value functions. Single-dimensional value functions are scaled so that the value of the lowest score on the evaluation measure is zero and the value of the highest score is one. Given this property of ...
