Abstract: The knowledge based system (10) functions in a machine initiated maintenance environment to provide efficient and timely maintenance of customer equipment (40). The knowledge based system (10) provides the failure evaluation function through the use of an expert or knowledge based system (11) that is installed in the customer equipment (40). The knowledge based system (11) makes use of a set of rules and hypotheses to operate on data collected from various points within the customer equipment (40) to monitor the operational integrity of the customer equipment (40). This knowledge based system (11) identifies the occurrence of a failure within the customer equipment (40) and functions using its rules, hypotheses and collected data to isolate the source of the error in the customer equipment (40) and, whenever possible, "fence" or isolate the failed field replaceable unit (70-75) that has caused the error.
