Abstract

Recently, as weapon systems have become more complex and multi-functional, the difficulty of the operation and maintenance of weapon systems in the military have become increasingly difficult. On the other hand, the service period of operations and maintenance workers who perform operations and maintenance has been shortened, and the skill of system operation and maintenance has been lowered. This complexity and multi-functionality of equipment cause malfunctions and errors of users and maintenance personnel, and degradation of the reliability affects availability and combat readiness. In addition, life cycle costs have been gradually increasing. Therefore, I would like to suggest an improvement plan of the design of weapon systems and ILS (Integrated Logistics Support) in order to examine the implications of failure in the military. The weapon system is operated in the ROK Navy. Data from 730 cases of failure of weapon systems was collected, and analyzed. The results of the analysis are classified into failures that can be prevented in advance and failures that cannot be prevented. This shows the portion of preventable failures in weapon systems and proposes measures to minimize failures.

최근 무기체계가 복잡화, 다기능화 됨에 따라 최종 사용자인 소요군의 무기체계 운용, 정비 난이도가 점점 높아지고 어려워지고 있다. 그러나 이와 반대로 운용, 정비를 수행하는 운용병, 정비병의 근무(복무)기간이 단축되면서 장비 운용, 정비에 대한 숙련도가 낮아지고 있으며. 이러한 장비의 복잡화, 다기능화는 사용자와 정비자의 오작동, 실수 등을 유발시키게 되고 이로 인한 무기체계의 신뢰성 저하는 가용도, 전투준비태세 및 고장수리에 따른 수명주기비용에 영향을 미치고 있다. 이에 따라 소요군에서 운용간 발생한 고장사례 분석을 통하여 시사점을 살펴보고 이를 개선하기 위한 설계측면, 종합군수지원(ILS) 측면의 개선방안을 제시한다. 분석된 무기체계는 현재 해군에서 운용 중인 무기체계로 야전 운용간 실제 발생한 고장사례 730건에 대하여 수집하여 분석하였으며 1차 적으로 고장원인별 분류된 결과를 2차로 사전예방 가능한 고장과 사전예방 불가능한 고장으로 분류하여 사전예방 가능한 고장이 어느 정도 차지하는지 정도와 이에 대한 시사점, 사전예방 가능한 고장별 고장 최소화를 위한 대책과 제안사항을 제시하였다.
