Research On Key Technologies Of Lifecycle Quality Management For Optoelectronic Product

The 21st century is the century of quality, and optoelectronic industry is one of the pillar cornerstone industries in the 21st century. For China optoelectronic enterprises, how to participate in the global competition by means of the world-class quality has become the survival or perish subject. Based on the theoretical study of quality management, as well as the analysis of optoelectronic products and its quality management characteristics, the optoelectronic product lifecycle quality management model is proposed in this dissertation, and some key technologies also are studied.(1) This dissertation studies optoelectronic products and its quality management characteristics, and proposes the optoelectronic product lifecycle quality management model which is customer demands-driven and six sigma process control targeted. By emphasizing the process control based on fact and data, the model could improve the quality advantages, achieve the continual satisfaction of customers, and enhance the core competitiveness of optoelectronic enterprise.(2) From the type of customer demands, in view of the optoelectronic product lifecycle quality management characteristics which is customer demands-driven, this dissertation brings forward the acquisition methods of customer demands based on web resources, and studies the cluster analysis method for analyzing the customer demands by fuzzy theory, and gives an application example.(3) Aiming at the reflection the customer demands throughout the various stages of the product lifecycle, this dissertation researches and establishes the quality house in order to achieve the mapping relationships between technical characteristics and customer demands. This dissertation also gives the methods for calculating the weight of technical characteristics, and helps enterprise to meet customer demands more effectively.(4) By studying the realization process of six sigma quality management for optoelectronic product, this dissertation discusses the 4-layer-monitor pattern to assure the implementation of high quality in process control, and the continual quality improvement ladder based on the PDCA ring and DMAIC model is also discussed. The dissertation studies the statistical process control methods of high-quality optoelectronic products. All these studies would be of great benefit to continual quality improvement in the process of optoelectronic product. (5) After analyzing the characteristic of high-quality process control, this dissertation respective discusses the application technologies of control chats such as the product defective rate, cumulative quantity of good product and consecutive conforming run-length, and gives the contrastive analysis examples to illustrate its. This study is helpful to diagnose the stability or abnormity of process.(6) This dissertation constructs the prototype system of optoelectronic product lifecycle quality management combined with the actual quality management of Foshan Nationstar Optoelectronics Limited Company. This dissertation introduces its implementation, and the results of application demonstrate the feasibility and advance of study contents in dissertation.The given optoelectronic product lifecycle quality management model and its key technologies are in favor of promoting the quality management theory and implementation for optoelectronic enterprise, which also has great significance for continual improving the quality level and participating in world-class competition for optoelectronic enterprise.
