Three steps are involved during an assessment procedure. The first step is to make a diagnosis for possible causes of the damage, the second is to perform a qualitative evaluation including classifying the current damage state and potential hazards, and the third step is to decide on the needed maintenance. The damage assessment procedure in SPERIL-3 is based on the above mentioned three steps. Therefore, the system consists of diagnosis as well as evaluation components. In this paper, the differences in the problem-solving between the diagnosis and evaluation systems are examined. The role of decision rules and information processing on the knowledge-based evaluation systems is discussed.
