Research on maintenance strategy of marine construction equipment system baced on Reliability Function Deployment

Research the characteristics of marine construction equipment systems and its Hall three-dimensional morphology. Quality Function Deployment (QFD) methodology was use to analyze the reliability of the equipment system and its ABC category. Make use of the method that the FMEA combines together with QFD to carry on RFD for the construction equipment system. To introduce the “implementation difficulty” and “revise importance” item in the RFD matrix, and to put forward a new idea about equipment management that is based on project and ABC classification of equipment system should be dynamic. It also recommended the establishment of a orchestration management mechanism of the construction equipments system and to divided the operating process of equipments system into category.
