Complex Goal Criteria and Its Application in Design to Criteria Scheduling y

Di cult real time AI problems require a means for expressing multi dimensional and dy namic goal criteria and a principled model for satis cing to best meet the criteria In the context of the Design to Criteria task scheduling paradigm we de ne a new general client spec i cation metaphor for describing such complex goal criteria or utility attributes and couple it with a principled evaluation model for using the criteria The criteria speci cation and corre sponding evaluation mechanism are used throughout the Design to Criteria scheduling process to focus scheduling activities on solutions and partial solutions that are most likely to meet the criteria i e to result in the focused production of custom satis cing schedules Examples of the power of the approach at reducing the complexity of the scheduling task and designing custom satis cing schedules are shown
