Most case-based reasoning (CBR) systems concentrate on retrieving cases which are most similar to a case at hand. When a similar case is found, the system will proceed to adapt (or modify) this solution to solve the case at hand. This method of problem solving cannot be easily applied in our real-world problem domain (i.e. insurance). In this domain, sufficient number of similar cases have to be retrieved so that the system could confidently calculate the final solution. More than one similar case must be retrieved due to the fact that most of the cases which are similar to the one at hand almost always contain inconsistent results. This paper describes a CBR system called risk cost adviser (RICAD) which applies a statistical function in order to propose a reliable answer. RICAD differs from other CBR systems as, in most cases, in addition to the use of the statistical function, it has to repeat its reasoning process until an adequate number of cases are collected to calculate the answer.
