Research on Building Method and Application of Quality Control Model for Marine Shaft System

Pointed the problem that it is lack of scientific quality control method in marine shaft system design in traditional design process for marine shaft system, building method of design quality control model for marine shaft system based on quality function deployment is studied. Meanwhile related problems of the model such as acquiring method for requirement indexes, weight calculation method for requirement indexes, weight calculation method for output indexes of House of Quality, are studied and solved. Furthermore, design quality control model for certain marine shaft system design is built, and quality basis of each design stage for the shaft system is clarified, which indicated that the research is effective and feasible. It shows that the design quality control model for marine shaft system could provide scientific basis for acquiring and mapping design requirements and quality control for marine shaft system design, which could also help to improve initiative, science and accuracy for marine shaft system design, and it has important theoretical significance and broad application prospects.
