A Malfunction Dealing Knowledge Database Design And Implementation On Shutdown Malfunctions Of Automotive Stamping

The level and the quality of stamping technology have an influence on the car manufacturing quality and the car manufacturing cost. For the car manufacturing enterprises, the production management in production is increasingly concerned about the shutdown malfunction occurs in the production. Reducing shutdown times and downtime are the conditions that the enterprise would improve production efficiency and quality, and increase the enterprise competition. Through the analysis of large shutdown malfunction records, found that the malfunction processing knowledge. For this kind of knowledge of storage and management, it is significant to help share knowledge and guide employees in solving shutdown malfunctions.The paper take a car production pressing workshop as actual background, combining with the production management in dealing with shutdown malfunctions business, to research and analysis the malfunction fact and knowledge of malfunction processing, focus on designing and building database of the malfunctions fact, and database of the malfunctions process knowledge, and the knowledge extraction algorithm design and implementation.Firstly, the paper combining with pressing workshop production business process, expounds systematically and stamping shutdown malfunction processing system framework. Through the system frame, the paper expounds the research orientation and the research content. Second, through the analysis of the data of the malfunctions, combining the facts of the malfunction structure, and analyzes the design malfunction fact database. Third, to analysis the malfunction process knowledge which is the reusable knowledge can guide the personnel business processing. Combined with the malfunction space model and the solution space model that making knowledge representation. According to the model parameter and elements, design knowledge database. Finally, using the database and computer programming method, build malfunction fact database and malfunctions process knowledge database and realize the treatment knowledge extraction algorithm.
