The reprint describes a strategy for assessing the completeness, but not the correctness, of the knowledge in a common type of expert system. Often decision makers are faced with the problem of selecting the best action to take in a situation. To solve such a problem, an ideal decision maker would determine the set of all actions that might be taken, evaluate the expected outcome of each action on all pertinent criteria, combine the single-criterion evaluations of each action into an overall evaluation of that action, and select the action with the highest overall evaluation. When an expert system solves such problems, the completeness of its knowledge may be assessed by determining whether the expert system considers all possible actions and whether it evaluates each action on all pertinent criteria.
