최근 러시아·우크라이나 전쟁에서 볼 수 있듯이 군수지원은 현대전에서 빼놓을 수 없는 중요한 요소 중의 하나이다. 군수지원은 모의 논리의 특수성과 복잡성으로 인해 대부대 분석 모델과 전문적인 기능 모델 중심으로 발전되어 왔지만, 교전급 분석 모델에서는 군수지원에 대한 요구가 상대적으로 높지 않았다. 그러나 대대급 이하 제대에서도 무인 수송자산을 이용한 재보급 필요성이 제기되면서, 이의 전투 효과를 분석하기 위한 모의 기법도 함께 요구되고 있다. 이에 본 연구에서는 대대급 이하 제대의 탄약 재보급 논리를 기반으로 교전급 분석 모델을 위한 재보급 과업 모델을 설계한다. 재보급 과업 모델은 다음과 같은 순서로 도출되는 의사결정트리를 기반으로 동작한다. 먼저, 사전 반복 모의실험을 통해 여러 가지 쌍방 교전 조건과 아군의 탄 잔여량에 따른 피아 손실교환비를 수집한다. 이어서, 쌍방 교전 조건, 탄 잔여량, 손실교환비로 표현되는 의사결정 트리를 만든다. 의사결정트리는 전투모의 실행 간에 적의 위협 강도, 피지원 부대의 탄 잔여량 등을 고려하여 재보급 우선순위를 결정하는 데 사용된다. 끝으로 제안된 모델의 실행 가능성을 OneSAF 기반 소부대 전투 모의실험을 통해 입증한다.

In this study, systems and procedures for improving the research and development and purchasing projects for defense specifications were investigated, and the current situation was analyzed in terms of the disclosure and establishment of defense specifications. I would like to discuss the measures that need to be taken to improve the specification affairs of our defense sector in order to improve the production quality of military supplies. It should be noted that it is necessary to establish specifications and procedures for improving the quality of domestically purchased military supplies. Therefore, it is highly imperative to systematically establish detailed performance, and miscellaneous specifications in order to actively respond to the rapid development of superior private technologies. In addition, the barriers in the entry of the defense industry should be removed through active disclosure of the specification data, and the opportunities for participation should be expanded to promote a smooth follow-up logistics support and to improve the quality of military supplies

방위산업은 경제논리보다 안보논리가 우선시되며 고비용, 장기간의 연구개발이 이루어져왔다. 하지만, 최근 몇 년간 급변하는 기술의 발전과 안보상황을 통해 방위산업에서도 체계개발간에 있어 비용절감과 개발기간 단축의 필요성이 대두되었다. 이에 민수 분야의 부품 모듈화 전략을 방위산업에서 활용하기 위해 OO 사업 LRU(Line Replaceable Unit)들의 모듈화 우선순위를 도출하고자 한다. 프로젝트 평가기법 중 하나인 GRA(Grey Relational Analysis)를 사용하였으며, 문헌연구를 통해 선정된 6개의 평가지표 데이터를 수집하여 OO 사업의 11개 모듈에 대하여 우선순위를 선정하였다. 그 결과, M11(메인보드)과 M8(EMI모듈), M3(싱글보드컴퓨터)의 Grey 관계등급이 0.83, 0.81, 0.80 순으로 도출되었고, 우선순위에 따라 모듈화 하는 것이 비용 절감 및 기간 단축의 효과가 있을 것으로 판단된다. 본 연구는 유사 무기체계 개발이나 향후 성능개량 사업 등을 고려한 LRU 모듈화 설계 시, 모듈화 적용 판단 및 의사결정의 근거가 되는 기초 연구로 활용할 수 있을 것이다.

With the rapid advancement and sophistication of defense weapon systems, the government, military, and the defense industry have conducted various innovative attempts to improve the efficiency of post-logistics support(PLS). The Ministry of Defense has mandated RAM-C(Reliability, Availability, and Maintainability-Cost) analysis as a requirement according to revised Total Life Cycle System Management Code of Practice in May 2022. Especially, for the project budget forecast of new PBL(Performance Based Logistics) business contacts, RAM-C is recognized as an obligatory factor. However, relevant entities have not officially provided guidelines or manuals for RAM-C analysis, and each defense contractor conducts RAM-C analysis with different standards and methods to win PBL-related business contract. Hence, this study aims to contribute to the generalization of the analysis procedure by presenting a cost analysis case based on RAM-C for the supply of military depot maintenance PBL project. This study presents formulas and procedures to determine requirements of military depot maintenance PBL project for repair parts supply. Moreover, a sensitivity analysis was conducted to find the optimal cost/utilization ratio. During the process, a correlation was found between supply delay and total cost of ownership as well as between cost variability and utilization rate. The analysis results are expected to provide an important basis for the conceptualization of the cost analysis for the supply of military depot maintenance PBL project and are capable of proposing the optimal utilization rate in relation to cost.

The 4th Industrial Revolution and the continuous development of Science and Technology have also required a speedy business promotion method in the defense industry. Advanced countries including the United States are already boldly innovating the existing high-cost and long-term acquisition system with the highest priority in weapons development to cope with the military rise of Russia and China. The Ministry of National Defense and the Defense Acquisition Program Administration have also recently introduced a quick acquisition system and are applying it to business promotion. In addition, some small-scale projects and weapons systems are being reorganized so that they can be managed by the units demanding them. After an organizational diagnosis of the Project Acquisition Group by the Ministry of National Defense in 2020, it has been reassigned as a subordinate unit of the Army Logistics Command from a direct unit managed by the Army HQ. As a result, problems such as work conflict or redundancy have been identified. In addition, a system has been implemented to shorten the acquisition period by applying a rapid acquisition program in the field of weapons systems by benchmarking the rapid acquisition program of advanced countries. The force support system project process will also need to introduce such a quick acquisition system. In addition, the Ministry of National Defense is considering ways to delegate some weapon systems to each military, which will then carry out tasks ranging from requirements determination to project management. Accordingly, it is now time to expand the organization for the management of the Army's weapons system acquisition project. Therefore, in this paper, the Army Project Acquisition Group was analyzed on its organization, acquisition procedures, and cooperation systems, with presentations of development plans for each field.

Supply units in each command are multi-tiered and each supply unit keeps a supply level independently, which can cause excess stock, leading false reports to the Logistics Command and increasing difficulties in managing user needs. This causes excess assets and the excess then causes deformation in demand. therefore, the supply support systems of our armed forces have become high-cost/low-efficiency and are insufficient to meet the needs of users in combat units. Civilian corporations and the US Department of Defense are downsizing the aforementioned multi-tiered supply systems thus revolutionizing efficient and effective logistics by adopting Supply Chain Management(SCM), and Prime Vendor policies. Prime Vendor policy is a logistics support method that allows users to directly request and receive supply items from suppliers, based on supply contracts between suppliers and central maintenance organizations like KDA. In other words, it is a system that allows for users to make orders to suppliers directly and suppliers to deliver goods to the users directly, cutting out the middle stage, thus allowing an efficient supply. This is a way forward in finance that cuts costs in net supplies and allows an efficient utilization of civilian assets. which is also known to fasten the speed of logistical support and stripping down the logistical structure. therefore, this report will explore Prime Vendor policies adopted in certain number of units for medical supplies that were taken in consideration of improvements in stock management in civilian organizations and the US Army, and aims to apply such policies for repair parts.

Purpose : The purpose of this study is to analyse affecting factors of Test and Evaluation and to improve the institution of Test and Evaluation in the Domestic purchase program. Methods : The domestic acquisition program is currently small in terms of size, but it is gradually increasing every year. Still, the domestic purchase program has insufficient regulations and procedures compared to the other procurement methods including research & development. Various problems are likely to occur between test and evaluation group, and defense industries regarding the regulations during Test & Evaluation. Therefore, the regulations and methods need to be amended to upgrade the current domestic purchase program into an effective and flawless one. In this paper, six variables have been chosen by the help of experts working in Ministry of National Defense (MND), Joint Chiefs of Staff (JCS), Army Headquarters and DAPA. Results : The six variables are effectiveness of proposal evaluation, fairness of test and evaluation, sufficiency of operational capabilities, seasonal period of test and evaluation, fulfillment in Integrated Logistics Support (ILS) of the industries, and guaranteeing appropriate environment for related enterprises' participation. Conclusion : This paper can help defense industries to enhance their development capabilities, and to perform tests more fairly and effectively considering the key factors identified in this research.
