Influence Metrics for Value and Utility Functions
Methods are proposed to measure the sensitivity of utility or value function to the variations of attribute values for Multi-Criteria Decision Analyses that are based on functions that cannot be expressed as a weighted sum of the attribute values. These measures, called factor Influence Metrics, can be used to examine the characteristics of the option scoring algorithm and help verify the algorithm is consistent with decision makers value structure and processes.
