Abstract

The purpose and main points of the ROK-US Navy were analyzed from various angles using the big data technology Word Cloud for efficient sea trials. First, a comparison of words extracted through keyword cleansing in the ROK-US Navy sea trial showed that the ROK Navy conducted a single equipment test, and the US Navy conducted an integrated test run focusing on the system. Second, an analysis of the ROK-US Navy sea trials showed that approximately 66.6% were analyzed as similar items, of which more than two items were 112 items Approximately 44% of the 252 items of the ROK Navy sea trials overlapped, and that 89 items (35% of the total) could be reduced when integrated into the US Navy sea trials. A ship is a complex system in which multiple equipment operates simultaneously. The focus on checking the functions and performance of individual equipment, such as the ROK Navy's sea trials, will increase the sea trial period because of the excessive number of sea trial targets. In addition, the budget required will inevitably increase due to an increase in schedule and evaluation costs. In the future, further research will be needed to achieve more efficient and accurate sea trials through integrated system evaluations, such as the U.S. Navy sea trials.

본 연구에서는 효율적인 함정 시운전을 위하여 빅데이터 기법인 워드 클라우드를 활용하여 한미 해군의 시운전 목적과 주안점을 다각적으로 파악하여 다음과 같은 결과를 도출하였다. 첫째, 한미 해군 시운전 종목을 키워드 클렌징을 통해 추출된 단어를 비교한 결과 한국 해군은 시운전을 단일 장비에 대한 시험의 개념으로 수행하며, 미 해군은 시스템에 초점을 둔 통합 시운전을 진행한다는 것을 알 수 있었다. 둘째, 한미 해군 시운전 연관도 분석 결과 약 66.6%가 유사한 항목으로 분석되었으며, 그중 2종목 이상 중복된 종목이 112종목이었다. 한국 해군 시운전 종목 252종목 대비 44%가 중복된 종목으로 미 해군 시운전 종목으로 통합시 89종목(전체 35%)이 축소 가능하다고 분석되었다. 함정은 여러 장비가 동시 다발적으로 작동하는 복합 시스템이다. 현재 한국 해군 시운전과 같이 개별 장비의 기능, 성능 확인에 중점을 두고 수행하는 것은 시운전 대상이 지나치게 많아져 시운전 기간이 증가하게 된다. 또한, 그로 인한 일정 및 평가비용 증가로 필요한 예산이 필연적으로 증가한다. 향후 미 해군의 시운전과 같이 통합 시스템적인 평가를 통한 효율적이면서 정확한 시운전을 위하여 추가적인 연구가 필요하다고 판단된다.
