The current methods, such as Binomial Probability Distribution or T-test, to calculate the number of samples of Precise Guided Missiles(PGMs) for test and evaluation are statistically problematic to make reasonable decisions thus use the budget efficiently. Also, the method to verify an accuracy rate of the PGMs using these old methods seems to be lack of objectiveness. This paper presents an effective, efficient solution adapted from the clinical medicine testing method of healthcare industry research, which may overcome our problems. This method considers and addresses both manufacturers' and consumers' risk simultaneously. By taking into account the weapon system project characteristics which take a relatively longer time and require higher-level budget, this approach also suggests a reasonable and feasible method to determine the amount of samples of the PGMs and making a criterion to verify an accuracy rate of the missiles that are required to test. Thus, this method is expected to contribute to acquisition and operations of high-reliability PGMs by MND and its field-users.

이문걸 ( Moon Gul Lee ),송철호 ( Chul Ho Song ) 한국항공경영학회 2014 한국항공경영학회지 Vol.12 No.2

공군의 비행 공역(이하, 공역)은 군 조종사의 특수비행, 시험비행 및 기타 작전, 훈련 비행을 위하여 설정한 구역을 말한다. 현재 공군의 공역 할당 방식은 주간 단위로 각 비행부대에서 원하는 공역 요구사항을 상위 부서 담당자가 경험과 직관에 의해 종합적인 고려요소를 판단하여 공역을 할당하고 있다. 하지만, 각 비행부대의 요구사항을 합리적이고 공정하게 반영하기에는 어려움이 있다. 이로 인해 원하지 않는 공역이 할당되는 결과가 초래되고, 이를 조정하기 위한 각 비행부대간의 공역 변경 협조 업무 등의 추가적인 업무가 발생됨에 따라 각 비행부대 비행스케줄러의 업무가 과다하게 발생한다. 따라서 본 연구에서는 이러한 문제점들을 해결하기 위하여 정수계획법을 기반으로 한 공역할당 구축 최적화 모델을 제시하고 실제 한국공군 공역할당과 관련된 사례 연구를 다룬다. 본 사례 적용 및 분석 결과는 매우 효율적이고 합리적인 공역할당 결과를 보여준다. The Air force`s military operations area(hereafter, airspace) is the airspace that is for training and special flights, flight tests and other operations. The current method of airspace allocation of the airforce is as follows. First, the person in charge of airspace allocation collects airspace requirements of each airbase on a weekly basis, and then allocates the airspace by hand with his own experience and intuition. As a result, each air base has unwanted airspace and thus additional task such as exchanging airspace between each air base to mediate this problem has been caused. In order to solve this problem, we propose the optimal airspace allocation method based on integer programming, and deals with the experiment results of Korea Air force`s real application that have fair and reasonable outputs in this problem.

Optimal Allocation Model of Anti-Artillery Radar by Using ArcGIS and its Specifications

Moon Gul Lee(이문걸) 한국산업경영시스템학회 2018 한국산업경영시스템학회지 Vol.41 No.2

It is very crucial activities that Korean army have to detect and recognize enemy’s locations and types of weapon of their artillery firstly for effective operation of friendly force’s artillery weapons during wartime. For these activities, one of the most critical artillery weapon systems is the anti-artillery radar (hereafter; radars) for immediate counter-fire operations against the target. So, in early wartime these radar’s roles are very important for minimizing friendly force’s damage because arbiters have to recognize a several enemy’s artillery positions quickly and then to take an action right away. Up to date, Republic of Korea Army for tactical artillery operations only depends on individual commander’s intuition and capability. Therefore, we propose these radars allocation model based on integer programming that combines ArcGIS (Geographic Information System) analysis data and each radar’s performances which include allowable specific ranges of altitude, azimuth (FOV; field of view) and distances for target detection, and weapons types i.e., rocket, mortars and cannon ammo etc. And we demonstrate the effectiveness of their allocation’s solution of available various types of radar asset through several experimental scenarios. The proposed model can be ensured the optimal detection coverage, the enhancement of artillery radar’s operations and assisting a quick decision for commander finally.

군에서 향후 미래 위협에 대비한 군용 항공기의 적정 소요를 분석하는 일은 중요하다. 이전의 연구들은 작전 임무수행 측면과 전력지수의 비교를 통하여 적정 소요를 분석하였다. 이 방법들은 단편적인 항공기의 전투-효과 지수와 수량 측면에서의 비교만을 실시하였다. 그러나 본 연구에서는 시스템 다이내믹스를 통한 군용 항공기의 실제 운용 시나리오에 기반한 시뮬레이션 분석을 실시한다. 군용 항공기 운용 개념의 특성을 반영하여 하부 주요 시스템의 고장률과 수리율, 전 평시 차별적으로 발생하는 피격률을 통해 적정 소요량을 산출한다. It is very important to evaluate proper acquisition of military aircraft against future threats in our military defense field. In previous studies, the evaluation has been determined in terms of tasking order or weapon power index. These methods compare the combat-effectiveness index and the number of aircraft. However, this study provides simulation analysis of proper quantity decision based on actual operational senarios of military aircraft using System Dynamics. The method reflects the properties of military aircraft operation concepts and considers the rate of failure of main systems on subsystems, as well as repair and crash rates caused by differentials in peacetime and wartime frame.

New Fictitious Play Procedure For Solving Blotto Games

이재영,이문걸,Lee, Jea-Yeong,Lee, Moon-Gul Military Operations Research Society of Korea 2005 한국국방경영분석학회지 Vol.31 No.1

In this study, a new fictitious play (FP) procedure is presented to solve two-person zero-sum (TPZS) Blotto games. The FP solution procedure solves TPZS games by assuming that the two players take turns selecting optimal responses to the opponent's strategy observed so far. It is known that FP converges to an optimal solution, and it may be the only realistic approach to solve large games. The algorithm uses dynamic programming (DP) to solve FP subproblems. Efficiency is obtained by limiting the growth of the DP state space. Blotto games are frequently used to solve simple missile defense problems. While it may be unlikely that the models presented in this paper can be used directly to solve realistic offense and defense problems, it is hoped that they will provide insight into the basic structure of optimal and near-optimal solutions to these important, large games, and provide a foundation for solution of more realistic, and more complex, problem

장영초(Jang Young Cho),이문걸(Lee Moon Gul) 한국경영과학회 2017 經營 科學 Vol.34 No.2

The artillery is a key element of the ground forces operation during wartime, and the military engineers support the artillery position development operation to support the smooth operation of the artillery. In establishing the artillery position development operation plan, the commander requires more than his intuition to find the best option reflecting a number of elements of the battlefield situation which changes every minute. Moreover, the number of available equipment is smaller than the number of required position developments, and the effective equipment operation becomes essential element of this issue. This study quantified the capability of the available engineering equipment, organized a number of teams enabling equipment to put out the maximum capacity based on the quantified figures, and formed the model which allocates the team to the developing points to minimize the developing time. The goal programming method was applied to resolve the problem. The developed model was applied to compare the total mission duration following the number of teams, the variable for commander"s decision, and the result of this study can be used as the quantitative data for commander"s decision making process in establishing the artillery position development support operation through effective equipment management.

무인항공기 공통 플랫폼 표준화를 위한 최적 분류 및 할당 모형

권기덕 ( Gi-duck Kwon ),이문걸 ( Moon-gul Lee ) 한국항공경영학회 2021 한국항공경영학회지 Vol.19 No.3

국방 분야에서 표준화의 필요성은 국방자원의 사용을 저비용이면서 고효율 기반으로 보장하므로 매우 중요하다. 군용 무인항공기 분야는 더욱 기술 진보화에 민감한 특성을 보인다. 현재의 우리나라의 산학연의 기술 수준과 소요군 목표 요구성능 간의 차이가 좁혀지지 않으면 획득이 지연되거나 현장 적시 적용성이 현저히 떨어지는 결과로 이어질 것이다. 또한 연구개발을 담당하는 입장에서는 다품종 소량생산이라는 구조 때문에 발생하는 낮은 사업성으로 인해 국가기술의 경쟁력이 저하될 것이다. 따라서 본 연구에서는 이러한 문제점에 대한 대안을 찾기 위하여 무인항공기의 계열화 및 군집화를 전제로 최적화 알고리듬을 적용한 수리모델을 기반으로 하여 공통 플랫폼 최적 분류 및 할당 모형을 개발하였다. 본 모형의 활용을 통해 현재 추진 중인 다양한 무인항공기 개발 및 획득 사업에서 개발하여야 할 대상 체계 범위를 축소하고 공통플랫폼화 및 기술표준화에 기여할 것으로 예상된다. The necessity of defense standardization is very important as it ensures that defense resources can be utilized at low cost and high efficiency. The military unmanned aerial vehicle sector is characterized by being a more sensitive business due to fast technological advancement. If the gap between the performance specifications required by the required military and the position of researching to make an unmanned aerial vehicle that satisfies the conditions is not narrowed, the relevant weapon system cannot be developed and introduced in a timely manner. Eventually, there will be a problem that the utility value of the weapon system is lowered, and the national technological competitiveness will also be deteriorated due to the low business viability arising from the structure of small-scale production of multi-species from the standpoint of research and development. Therefore, in order to solve the problem, this study proposes a common platform optimal classification and matching model based on a mathematical model for applying by basis of the premise of unmanned aerial vehicle sequencing and clustering. Through suggested model, it we can contribute to rearrange and mange to current numerous UAV programs efficiently.
