Failure Mode, Effects and hazards Analysis (Failure Mode Effects and Criticality Analysis, FMECA), a method of inductive Analysis for system, especially the equipment safety and reliability Analysis, the purpose is to find all kinds of affecting system reliability Analysis of defects and weak links, and for the effective management system, analytical review accident, corrective or preventive plan provides the basis.

The Reliability Centered Maintenance (RCM) is based on the fault mode of the driven equipment. According to the influence of the fault mode on the whole system and its failure characteristics, the logical decision method is used to determine the targeted Maintenance strategy. RCM is a technology based on reliability analysis method to achieve maintenance strategy optimization, especially suitable for large units. Its purpose is to obtain the minimum maintenance resource consumption of equipment while meeting safety, environmental technical requirements and working requirements.
