The Application of Reasoning Strategy in the Fault Diagnosis

Mill’s Five Methods is applied to the fault diagnosis as reasoning strategy. As a description of interaction between the elements in a system, the function diagram includes all the possible elements. Meanwhile, the irrelevant elements should be ruled out or checking the relevant one in an optimized order according to the different circumstances. Mill’s Five Methods is applied to solve the problem. However, Mill’s Five Methods can only solve the single cause problem. Thus, the system theory should be employed as auxiliary. By the composite application of Mill’s Five Methods and system theory, an optimized checking order can be provided and the cause can be determined effectively.
