Knowledge Management for Design Development and Maintenance through Text Mining of Product Information

（Knowledge Management for Design Development and Maintenance using Product Development History Information and Product Defect Response Information）

Abstract

We aimed to develop a method to assist knowledge management of design development and maintenance in PLM in the automotive manufacturing industry by utilizing text mining. By systematizing the knowledge between parts described in the ECR and linking it with departmental knowledge, we have established a method to systematize the knowledge between parts described in the ECR and link it to departmental knowledge. Failure propagation knowledge was modeled, and a system was developed to transfer this knowledge to young engineers. By combining the knowledge of texts from different ECR and FPR situations, we proposed a relationship between parts that can affect the entire PLM.
