Research on Failure Behavior Rule Base and Reasoning Engine Establishment Method

The mining and refining methods of failure behavior rules and the establishment method of reasoning engine are studied. We propose a mining method of related mechanisms, including the preprocessing of data based on domain knowledge, and the use of FP-growth algorithm to mine frequent item sets and correlation analysis to obtain related failure mechanism information. On this basis, the expert system technology is used to establish the failure behavior rule base, and through the iterative reasoning, all the preconditions needed to reach the final state are obtained, and the reasoning engine is established.
