In troubleshooting large scale equipments, fault localization interferences involve indeterminateness and they might lead to erroneous conclusions. To realize indeterminate inferences, an assumption-based fault localization technique has been developed. The technique allows inferences based on indeterminate assumptions. When inconsistencies are discovered, assumption are revised. The technique also enables flexible diagnosis control, such as reasoning based on anticipated test results without actually carrying out the tests. When the anticipated results become doubtful, it activates the omitted tests. The paper describes the technique and an outline of the troubleshooting expert system for electronic switching systems based on the technique.
