Application of Comprehensive Hierarchy Method to the Fault Diagnosis of Marine Power Plant

Based on the structure hierarchy, function hierarchy and fault hierarchy of marine propulsion plants, the elassified hierarchy system is established by a synthetic method, whieh divides the marine propulsion plants into several parts. With this method, the faults can be diagnosed and reduced to a small range, and then the types of faults and the idiographic physical positions can be aseertained quiekly and aeeurately.
