This paper will use fuzzy parameter method to record the important machine parameters. First, we can solve the degree of membership functions of fault fuzzy parameters. Then, the weight of the fuzzy membership function can be obtained by the Analysis Hierarchy Process with Matlab software. Finally, the result of synthetic fuzzy membership function of each cylinder can be used to find out the engine real faults and time relationship. In addition, such model analysis is suitable for the real ship and others sister ships maintenance programs.
