ESWBS 기반 품질정보를 활용한 함정 품질보증업무 효율화 방안 연구

The Expanded Ship Work Breakdown Structure (ESWBS), developed as an enhancement of the Ship Work Breakdown Structure (SWBS), extends the existing three-digit coding system to a five-digit format to broaden the scope of ship management from Integrated Logistics Support (ILS) to Total Life Cycle System Management (TLCSM). The newly established ESWBS of 2024 provides more detailed equipment codes, enabling the identification of common elements among different naval vessels. From a quality assurance (QA) perspective, this framework establishes a systematic approach to storing and using quality information throughout the total life cycle of a vessel. The ESWBS enables structured and integrated management of quality data, enhancing efficiency in defect prevention, root-cause analysis, and data-driven decision-making. On the other hand, the procedures for systematically managing quality information based on ESWBS codes remain insufficient. This study applied ESWBS coding to quality information from the Ulsan-class Batch-OO lead ship, classifying issues according to the stage, cause, and technical system. The results show that the ESWBS-based classification structure clarifies the distribution of quality issues and supports preventive QA, highlighting its potential to improve quality-management efficiency across future naval vessels.
