초록

본 연구는 시뮬레이션 기반 RAM-C 분석에서 행정 및 군수지연시간(ALDT)의 구성요소 설정이 운용가용도와 동시조달수리부속(CSP) 비용에 미치는 영향을 분석하였다. ALDT를 72시간으로 고정하고 조달시간과 이동시간의 구성비를 변화시키는 민감도 분석을 수행하였으며, 기준 시나리오를 중심으로 조달시간과 이동시간을 각각 변화시킨 결과, 조달시간 증가는 CSP 확보를 통해 운용가용도를 일정 수준 유지할 수 있었으나, 이동시간 증가는 CSP 확보만으로 보완하는 데 한계가 있는 것으로 나타났다. 이를 통해 동일한 ALDT를 적용하더라도 구성요소 설정에 따라 RAM-C 분석 결과가 달라질 수 있으며, 시뮬레이션 기반 분석에서는 사업별 운용환경을 고려한 ALDT 구성요소의 개별 설정이 중요함을 확인하였다.

Abstract

This study analyzed the effects of administrative and logistic delay time (ALDT) component settings on operational availability and concurrent spare parts (CSP) cost in simulation-based RAM-C analysis. A sensitivity analysis was conducted by fixing the total ALDT at 72 h and varying the proportions of lead and transportation times. Furthermore, the effects of each factor were analyzed independently based on a baseline scenario. The results showed that an increase in lead time could maintain operational availability to some extent through additional CSP provisioning, whereas the effect of increased transportation time could not be fully compensated by increasing CSP. These results demonstrate that RAM-C analysis outcomes can vary depending on how ALDT components are configured, even when the same total ALDT is applied. Therefore, in simulation-based RAM-C analysis, individual ALDT components should be appropriately configured by considering the operational environment of each weapon system.
