【Abstract】 Quality is the basis for survival and development of manufacturing enterprises in the competitive market. Instructed by the theory of lean manufacturing and process management, the quality navigation method for workshop production process in small- and medium-sized manufacturing enterprises (SMMEs) was advanced, and the working principle was discussed. Based on the proposed method, key technologies for lean quality navigation were researched. The main work of the dissertation was as follows:Chapter 1 was introduction, which presented the research background. Firstly, problems of quality management in workshop production process were brought forward by discussing the actual manufacturing process in enterprises. Secondly, the related theory of quality management was reviewed and analyzed, and the shortage of present research was proposed. Finally, the purpose and research significance was explained, and the content and framework of the dissertation were introduced.In chapter 2, SMME-oriented lean quality navigation was studied. Characteristics of quality management in SMMEs were summarized, and the concepts of quality and stability in workshop production process were defined. Based on the principles of quality management in lean manufacturing, the concept of lean quality navigation was given. Then the working principle was explained on the basis of a concept model of lean quality navigation, and the structure model was built. Meanwhile, the key technologies of implementing lean quality navigation were discussed.In chapter 3, the method to build a coordinate system of lean quality navigation and navigation map was researched. Based on the definition of process, the coordinate system of lean quality navigation was built to describe the quality of workshop production process. The model of workshop production process was established to analyze the data components of navigation map, and graph theory was utilized to build navigation map with detailed approach, then the actualization process was given with an example. In chapter 4, the principal technologies of actualizing lean quality navigation were researched. Based on the coordinate system in chapter 3, a lean quality index system was established, in which corresponding parameters were selected. A computation model was built to estimate the quality of workshop production process, and regression analysis was applied to analyze the quality state. The technique to estimate and analyze the quality stability was studied on the basis of the maximum entropy principle. A simulation-based method for two-dimensional improvement was discussed.In chapter 5, the research in this dissertation was summarized, and future investigation directions were pointed out.更多还原
