PROBLEM TO BE SOLVED: To support human judgement by generating a judgement tree which is provided with judgement standards matching to purposes most by giving thereto expected values as judgement information according to respective events which are generated by selected actions, and their occurrence probabilities and effect values, and dynamically updating the occurrence probabilities and effect values. SOLUTION: The judgement tree of respective curing methods, i.e., a tree structure having as branches selected actions of curing and events resulting from the actions is stored previously in a judgement tree data storage part together with occurrence probabilities of the respective branches. Occurrence probabilities are obtained from a data base wherein the respective curing methods and their results are totalized as evidences. The judgement information is embodied as a tree structure of the judgement tree, occurrence probabilities of the respective branches, and effect values of the events at respective branch terminals. When a judgement item is inputted from an input part 2 so as to determine a curing method for a patient, expected values of respective actions are calculated from the occurrence probabilities of the respective branches and an effect value on which the intention of the examinee is reflected. The occurrence probabilities can be corrected with attributes information on the examinee. |
