BOM과 디지털 트윈 통합 데이터베이스 기반 스마트 커넥티드 제품의 설계변경에 대한 연구

Abstract

This study shows how closed-loop environment supported by integrated bill of material (BOM) and digital twin databases enables engineers share operational data of their products to enhance decision makings for their engineering changes. To test feasibility of the concept, this study proposes an architecture of integrated BOM and digital twin databases for supporting engineering changes of smart, connected products. In the architecture, digital twin databases allow BOM databases to share digital twin objects with their record of sensor data through their product configuration identifiers. This study implemented the architecture with a prototype product data and digital twin management systems. Using the implemented system, this study has developed smart, connected mannequins and managed their product usage data in a digital twin database. The implementation and management experience shows that the operational data of digital twins can support engineering changes with integrated and consistent online machine generated product usage data to allow efficient procedures of engineering changes and verifications of their results.
