Knowledge management system for failure analysis in hard disk using case-based reasoning

Hard disk failure is a serious problem in term of product quality and credibility to customers. All hard disk drive companies need to be aware and address how to get rid of failure and prevent the repeat of the problem in their products. The quality of failure analysis process depends on the person who has most experience. It would not be so efficient if the company has no experienced person to perform the analysis. A knowledge management system can store the knowledge of experienced engineers. It can help new engineers to learn the craft. It would reduce a knowledge gap issues and bring up efficiency for failure solving process. This paper presents a design and implementation of knowledge management system for failure analysis in hard disk with case-based reasoning. The existing cases are stored and a new case can be compared to the existing one in order to retrieve the relevant existing knowledge to help the analysis. Once the new case is solved, it can be stored to aid the future cases. A prototype of the system has been implemented and the assessment of user satisfaction shows that it can improve the failure analysis process effectively.
