Design the reasoning process of EDDM by fuzzy rule-based method

In this article, the reasoning process by use of fuzzy inference is developed based on the previously proposed error detection and diagnosis mechanism (EDDM) for fault-tolerant system. The detection mechanism employs the hook process to retrieve the message in and between the various application programs and the operating system, and detects whether the AP failed. The diagnosis mechanism with the reasoning process can identify the failure cause of the message, and make inferential prediction on the executing application program as to determine whether there is any trend toward failure. Fuzzy inference method for failure event including definition of fuzzy set and linguistic variables, design of fuzzy rules and evaluation of fuzzy result, etc. is investigated.
