FASCAM is a newly introduced mean against enemy fire power and supposed to be scattered on base areas in front of a tunnel so as to deter maneuver and shooting of enemy artilleries. However, for its characteristics different from conventional munitions, only a few studies have been undertaken on operations system using this new measure. In this research, we propose a procedure to describe and analyze mathematically an operation system for suppression of enemy fire power using FASCAM. Two suggested simulation methods, impact point generation and density integration, both can describe the actual operation rationally and each has advantages of its own respectively. Further, we demonstrated an example analysis to derive an optimal suppression plan based on the proposed procedure.

저고도 궤적의 장사정포 위협이 대두됨에 따라 이를 방어할 요격 시스템의 개발이 시작될 예정이다. 이러한 장사정포의 공격을 방어하는 문제는 전형적인 동적 무기 표적 할당 문제다. 동적 무기 표적 할당 문제에서는 한 시점에서의 의사결정 결과가 이후 시점의 의사결정 과정에 영향을 주며, 이는 마코브 의사결정 모형의 특징이기도 하다. 장사정포의 공격을 방어하기 위한 의사결정 과정에 허용되는 시간은 공격자와 방어자의 거리를 고려할 때 저고도 궤적의 동시 다발성 발사체에 대한 대응은 수 초 이내에 결정되어야 하나, 짧은 시간 내에 마코브 의사결정 과정으로 최적해를 구하는 것은 불가능하다. 본 논문에서는 장사정포 공격을 방어하는 동적 무기 표적 할당 문제를 마코브 의사결정 문제로 나타내고, 3가지 시나리오를 작성한 후 근사적 동적계획 방법을 적용하여 요격이 가능 시간 안에 해의 도출이 가능한지를 시뮬레이션을 통하여 확인하였다. 도출된 해의 품질을 검증하기 위하여 각 시나리오에 대하여 근사적 동적계획을 적용한 결과와 Shoot-Shoot-Look 방법을 적용한 결과를 비교하였다. 시뮬레이션 결과, 장사정포의 방어 시나리오에 대하여 근사적 동적계획의 결과가 Shoot-Shoot-Look 방법을 이용한 결과보다 우수함을 보였다.

In Korea, military authorities have neglected to consider impacts of military projects on local communities and natural environment. Moreover, local communities have had difficulties in dealing with the Ministry of National Defense (MND), which was stubborn enough not to implement environmental assessment on their projects. In this situation, recent case, "EIA of Baekgol Division's Howitzer Fire Training Site" in the Supreme Court-in which judges upheld the Higher Court's decision that the division violated the Environmental Impact Assessment law by ignoring to implement EIA-reveals that military projects can no longer forgo environmental assessment. The decision has serious ramifications on the future of Environmental Impact Assessment in military-led projects. This paper examines the proper scope of EIA in military-led projects and, more specifically, fire training site and searches for how to improve it through 'probable error,' a military training method that is applied to real 'howitzer' fire training. Probable error of the artillery field manual is nothing more than an error that exceeded as often as it is not exceeded and its scientific method was demonstrated through real fire tests in the US. Army. If it is applied to improve assessment methods about the proper scope of EIA in military 'howitzer' fire training site, 'probable error' will improve effect prediction, mitigation and reliability.

We focus on the weapon target assignment and fire scheduling problem (WTAFSP) with the objective of minimizing the makespan, i.e., the latest completion time of a given set of firing operations. In this study, we assume that there are m available weapons to fire at n targets (> m). The artillery attack operation consists of two steps of sequential procedure : assignment of weapons to the targets; and scheduling firing operations against the targets that are assigned to each weapon. This problem is a combination of weapon target assignment problem (WTAP) and fire scheduling problem (FSP). To solve this problem, we define the problem with a mixed integer programming model. Then, we develop exact algorithms based on a dynamic programming technique. Also, we suggest how to find lower bounds and upper bounds to a given problem. To evaluate the performance of developed exact algorithms, computational experiments are performed on randomly generated problems. From the results, we can see suggested exact algorithm solves problems of a medium size within a reasonable amount of computation time. Also, the results show that the computation time required for suggested exact algorithm can be seen to increase rapidly as the problem size grows. We report the result with analysis and give directions for future research for this study. This study is meaningful in that it suggests an exact algorithm for a more realistic problem than existing researches. Also, this study can provide a basis for developing algorithms that can solve larger size problems.

In this paper, we will discuss the absolute angular error control mode for the Gun/Turret driving system. The Gun/Turret driving controller receives absolute angular error calculated from the fire control system (FCS). Thus, the Gun/Turret driving controller is subjected to step command to cause residual vibration and system unstable. In order to reduce residual vibration and to ensure the system stability, we propose an error motion profile method with two types of trapezoidal and S-Curve. The validity of the proposed error motion profile method is confirmed via simulation by observing that the resulting position error, driving power, and power density satisfied the control performance.

본 논문에서는 천안함 폭침사건과 연평도 포격전으로 서북도서의 중요성이 부각됨에 따라 서북도서를 본토로부터 분리된 전구로 보고, 이에 대한 특징과 현실태를 고려하여 NCOE 구축방안을 제안하였다. 서북도서는 전략적 가치가 있음에도 불구하고 그동안 감시정찰체계, 지휘통제체계, 정밀타격체계의 효과적인 운용을 위한 체계적인 NCOE가 구축되지 못한 상태였다. 따라서 아키텍팅에 의한 방법을 활용하여 개선소요를 도출하였으며, 개선소요 중 전구 ISR 자산과 연계한 K-9자주포의 북한 갱도포병 타격체계 개선은 작계분석모델에 의한 시뮬레이션을 수행한 결과, 타격효과가 크게 향상된 것으로 나타났다. 이러한 NCOE 구축방안은 서북도서와 같은 분리된 전구작전을 위한 군사력 건설과 작전수행체계 구축의 표준모델로서 기여할 것으로 기대된다.

In weapon systems development, live fire tests have been frequently adopted to evaluate the performance of the systems under development. Therefore, it is necessary to ensure safety in the test ranges where the live fire tests can cause serious hazards. During the tests, a special care must be taken to protect the test and evaluation (T&E) personnel and also test assets from potential danger and hazards. Thus, the development and management of the range safety process is quite important in the tests of guided missiles and artillery considering the explosive power of the destruction. Note also that with a newly evolving era of weapon systems such as laser, EMP and non-lethal weapons, the test procedure for such systems is very complex. Therefore, keeping the safety level in the test ranges is getting more difficult due to the increased unpredictability for unknown hazards. The objective of this paper is to study on how to enhance the safety in the test ranges. To do so, an approach is proposed based on model-based systems engineering (MBSE). Specifically, a functional architecture is derived utilizing the MBSE method for the design of the range safety process under the condition that the derived architecture must satisfy both the complex test situation and the safety requirements. The architecture developed in the paper has also been investigated by simulation using a computer-aided systems engineering tool. The systematic application of this study in weapon live tests is expected to reduce unexpected hazards and test design time. Our approach is intended to be a trial to get closer to the recent theme in T&E community, "Testing at the speed of stakeholder's need and rapid requirement for rapid acquisition."

The artillery fire accident in Yeonpyeong Island showed that the man-made disaster caused by the domestic political conditions as well as the conventional natural disaster can occur in Korea. Especially, it can be known that the whole community can be abandoned despite of a small scale of practical damage in residential district and the resulting large scale of refugees can be produced in the nation. This study investigated the real condition of temporary housing which has been provided at the Island. Firstly, in the theoretical review based on the literature study, the content on the background of temporary housing, the providing procedure of its concept, the status of supply, etc. has been considered. And it researched the current condition of the entire temporary housing through the questionnaire and interviews targeting the residents in the Island. So it purposed to make use of the results as a plan and design for future temporary housing against disaster.
