Enabling Agents to Perform Prioritized Multi-Criteria Aggregation

Ronald R. Yager

Many agent based decisions involve an aggregation of the satisfaction to multiple criteria. We consider the situation where there exists a prioritization relationship over the criteria. In this situation increase in satisfaction to a lower priority criteria doesn't readily compensate for a decrease in satisfaction in higher priority criteria. Typically the relationship between safety and cost manifests this property. We suggest that prioritization between criteria can be modeled by making the weights associated with a criteria dependent upon the satisfaction of the higher priority criteria. We discuss a number of methods for obtaining the associated weights.
