Study On FA Expert System For Product In Quality Layout Process

It is essential to make research on fault analysis of expert system facing product to adapt to market competition, response to the development of society. The research is important for designer to solve how to convert the customer requirement into the process of manufacture and to prevent fault in the process of production. Based on a wide exploration into the relevant papers and studying the recent achievement and the developing trends in the field of FA, this dissertation made a systematic and profound research on fault analysis of expert system facing quality layout. These researches mainly included: The fault analysis is completely researched. This dissertation made a systematic and profound research on fault analysis of expert system is put forward. The function modelling and the information modelling for FAES is established. It probes into the knowledge described and processed, the knowledge maintenance, management and layout of the FAES system; and develop FAES based on product facing the quality layout.The whole dissertation is divided into six chapters.Chapter one introduce the history and the significance of the FA facing quality layout in product design and quality management for enterprise. The recent research on FA was surveyed. The developing and future prospects of the research were also discussed. And the whole research work in this paper was proposed.Chapter two, It described quality function deployment (QFD), a kind of method for quality layout, and put forward the systematic layout of the joints among quality layouts. It completely researched many FA's methods relating to fault tree analysis(FTA) and failure modes effects criticality analysis(FMECA).probed into fuzzy failure modes and effects ,critical analysis(FFMECA),and the joints between FFMECA and FTA.Chapter three, it put forward FAES's layout, it establish the information model of the FAES, the FAES and the computer-aided building tree for fault in the product design and research the relation among all kind of information modelling.Chapter four, it design the FAES, it generalize and analyse the knowledge of the FAES, and probe into the process of knowledge described and analysed in detail, emphasize the right acquiring and transform way, and research the interface of knowledge between FAES and QFD. It designs the system DB.Chapter five, it illustrates the development of FAES facing bearing in the process of production.Finally, chapter six, it made a conclusion of the whole dissertation and looked forward the future research work.
