Abstract: Combining of fuzzy mathematics, fuzzy diagnosis principle and automatic detection technology, an expert system for ship log fault diagnosis based on fuzzy reasoning is proposed. According to the characteristic of ship log, it designs hardware platform and combines fuzzy relational matrix with semantic distance by fuzzy production knowledge representation method to design and realize each functional module of the ship log fault diagnosis fuzzy expert system. Experimental results show that the fault diagnosis fuzzy expert system is able to identify the fault efficiently and reliably.

Key words: log, fault diagnosis, fuzzy reasoning, fuzzy expert system
