Research on the Assistant Decision-making of Gas Regulator Based on Case-based Reasoning

In order to improve the efficiency of fault decision-making of gas surge tank, this paper proposes a case- based reasoning (CBR) for assistant decision-making of gas surge tank. On the basis of the real case of surge tank fault, the characteristic attributes of the case are extracted, and the case is represented by the frame representation method. Through analytic hierarchy process, local similarity calculation model and global similarity calculation model, the assistant decision-making method of gas surge tank based on case-based reasoning is established. Finally, the source case and target case are analyzed, and the results are proved. The application of this method in assistant decisionmaking of gas surge tank fault has practical significance.
