A decision making structure is established by an expert having a plurality of linked nodes. Random values of the input parameters are generated, which includes biasing the random values by a function of a preceding response. The steps are repeated until a sufficient number of responses having a predetermined statistical significance is achieved for each node. After this set up and teaching, the accuracy of the systems's predictions may be verified against actual responses by the expert. The decision making structure may be interrogated by entering a situation to be analyzed. The path the expert would take through the decision making structure is predicted by determining the probability of the expert's response at each mode in the structure to arrive at an output action. A plurality of structures may be established, one for each individual expert, allowing interrogation of any or all of the decision making structures.Other References
