The dissertation studies the warranty cost management from the point of the integration management. Based on the review of the theories on warranty cost management and the analysis of the current problems of warranty management in enterprises, it presents the basic theory and management mode of integrated warranty cost management and studies the characteristics and problems of the warranty cost estimation and warranty cost optimization control on integrated warranty cost management environment in depth, combined with the integration methods. The major results include the followings:
First, the dissertation reviews and analyses the research on warranty cost management, and then puts forward the further study area.
Second, the dissertation analyses the characteristic, formation mechanism and influence factors of warranty cost management, studies the system structure and management characteristics, formulates the theoretical framework of applying the integrated warranty cost management. And then it presents the management mode and framework of the integrated warranty cost management, and introduces the components of the structure.
Third, based on the analysis of the characteristics of the warranty cost estimation on integrated warranty cost management, the dissertation presents the warranty cost estimation method based on CBR on design stage. This method solves warranty cost estimation problems on design stage with few data and incomplete information, using FMEA knowledge model and CBR technologies. And then, it presents the warranty estimation method based on feature mapping technology, which realizes the transformation from the warranty cost to design information, and manufacturing process information and solves the problems of warranty cost estimation on product manufacturing stage.
Fourth, the dissertation studies the warranty cost optimization control method of the integrated warranty cost management from the points of warranty policy management and product quality control. Based on the consideration of the competitive factors in the market, it develops the product sales rate function by using the market variables, and presents the dynamic optimal control theory to obtain optimal strategies of the product quality, price and the warranty policies over time. Considering the analysis of the reliability management with limited resources, it studies the reliability management method based on the failure analysis, which can control the warranty cost through controlling and improving the product reliability.
At last, the dissertation studies and analyses the problems of the warranty management in FAW JIE FANG QING DAO AUTO FACTORY. And then it presents the integrated warranty management system that is suitable for the company. Good results are achieved through the implementation of integrated warranty cost management within the company, which supports results of the study.
