Research Of Process Modelling And Knowledge Management Method In Led Chip Manufacturing Flow

In the Knowledge Economy, like capital, labor and material, knowledge can be used as a factor of production. In the new century, the competition among the enterprises has transformed into the competition of knowledge they owned. Enterprise has to manage knowledge in order to maintain its competitive power.In the LED (Light Emittting Diode) manufacturing process, almost all the sections such as Craftwork Programming, Manufacturing Process, Maintenance of Equipment and Condition Monitoring have the requirement to execute knowledge management (KM).Combining with the background of the realization of the information system of Guangdong Fortune Electronical Material Ltd. and the management requirements of integration, high-eficiency and human resource capital, we advance a manufacturing KM system based on the development of the FEMC and develop a prototype system.First of all, we introduce the research background,present condition of manufacturing knowledge management,analyse the semiconductor lighting industry, advance the thesis keypoints and structure. Then we research the manufacturing process based on the workflow theory, establish the LED chip manufacturing meta-model based on IDEF0 methods, express the workflow in the form of extensible markup language (XML), which create a excellent foundation for the manufacturing flow based on workflow. In this paper we summarize the content of the semiconductor workflow and abstract the main knowledge. Based on the KM of process knowledge based on the instances, manufacturing process knowledge based on the ontology and quality knowledge based on the rules, we implement the knowledge integration founded on the workflow research. Finally, based on the reseach of workflow and knowledge management, we use the Java development circumstance JSDK1.4.2, Java translator tool JBuilder9.0 and web server Weblogic7.0, the workflow engine Shark1.0, Knowledge management platform Protégé3.2.1 to eatablish a prototype system.Its significance of enlarging the application of manufacturing management system is instructive.
