Case and Model Based Hybrid Reasoning for Group Decision Making

Several organizational decision-making situations are critical and recurring in nature. The processes involve groups performing periodic and repetitive activities. It appears logical that the development of a shared repository that stores the experience invoked in prior decisions and retains the rules, policies and procedures of an organization can be useful for subsequent groups engaged in similar decision-making activities. We describe, in this paper, an approach that combines a case-based reasoning method and a model based reasoning method. The main goals are to reduce the time required to come to a decision, particularly, in a contingency situation, to compensate for lack of experience of young operators, and to distribute available experience to different sites.
