製品情報のテキストマイニングによる設計開発・保守のナレッジマネジメント

（製品開発の履歴情報と製品不具合の対応情報を活用した設計開発，保守のナレッジマネジメント）

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.
