Claim One:
1. A method of fault diagnostics in a case based reasoning system, wherein said case based reasoning system comprises a plurality of cases, each case having an associated solution and a case weight, said method comprising the steps of: i) receiving data associated with a fault; ii) determining a case match indicative of the degree of matching between the received data and each of the plurality of cases; iii) providing a solution associated with one of the plurality of cases in dependence on its case match and case weight; iv) receiving an actual solution to the fault; v) increasing the case weight of the case associated with the provided solution if the actual solution is equal to the provided solution; and vi) adding a new case to the plurality of cases if the actual solution is not equal to the provided solution, wherein the actual solution is associated with the new case.
