With the development of modern science and technology, weapon systems such as tanks, submarines, combat planes, radar are also dramatically advanced. Among these weapon systems, the ballistic missile, one of the asymmetric forces, could be considered as a very economical means to attack the core facilities of the other country in order to achieve the strategic goals of the country during the war. Because of the current ballistic missile threat from the North Korea, establishing a missile defense (MD) system becomes one of the major national defense issues. This study focused on the optimization of air defense artillery units' deployment for effective ballistic missile defense. To optimize the deployment of the units, firstly this study examined the possibility of defense, according to the presence of orbital coordinates of ballistic missiles in the limited defense range of air defense artillery units. This constraint on the defense range is originated from the characteristics of anti-ballistic missiles (ABMs) such as PATRIOT. Secondly, this study proposed the optimized mathematical model considering the total covering problem of binary integer programming, as an optimal deployment of air defense artillery units for defending every core defense facility with the least number of such units. Finally, numerical experiments were conducted to show how the suggested approach works. Assuming the current state of the Korean peninsula, the study arbitrarily set ballistic missile bases of the North Korea and core defense facilities of the South Korea. Under these conditions, numerical experiments were executed by utilizing MATLAB R2010a of the MathWorks, Inc.

The fire effectiveness and the operationability of the ground weapon system (such as tank, armored vehicle, howitzer, MLRS, ${\cdots}$), whose operations are usually happened on the ground, are dependent not only on their performances but also on the terrain environments. Especially, the artillery weapons systems' effectiveness is largely varied, because their maneuverability (such as translation, occupation of their sites) and the fire effectiveness are very dependent on the terrain. In this paper, presented are the methods how to analyze the terrain using the digital terrain data. And a software (which are implemented on the IBM PC compatible personal computer) is developed for the analysis of the terrain using the various method of computer Aided Geometric Design and Modeling. The S/W is expected to be very useful for the evaluation of the artillery weapon systems and for the commanders' decision making.

In recent warfare, importance of counter-fire is increased. New weapon system and counter-fire have critical impact on defeating of the enemy. At an initial battle counter-fire, we need to study about striking plan against the enemy mine artillery. In this paper, we studied, using MANA(agent based model), how much cannon's hit probability and UAV-based target acquisition have influence on striking the mine artillery. We constructed MANA model based on the characteristics of a regional database of Korean peninsula. If we develop detail database of the ROK Army, the proposed MANA model can be used as a war-game model for the regimental level of the Army.

For the purpose of launching strikes, initial survivability of self-propelled artilleries is of crucial importance despite the fact that they are mobility weapon systems. This study identifies the combat placement possibility of the reinforced concrete box-type artillery positions, which might enable the replacement of the current igloo-types, in terms of cost and protection capability. In the numerical analysis the obtained numerical values have proved that these facilities have sufficient protection capability. In addition, it could be concluded that these facilities are also cost-competitive, if more than five positions are constructed simultaneously.

We have developed a weapon effectiveness evaluation model for top-attack smart munitions(WEEM/TASM), which is a many on many Monte Carlo Model evaluating the effectiveness of top-attack smart munitions against armoured ground vehicles. In this model the battle is reduced to a one-sided battle situation in that the target vehicles are regarded as being stationary and passive. It can simulate the whole attack process of smart munitions from firing artillery dispenser to sensing and hitting processes after dispense. It can also calculate the probability of kill of each target and the numbers of rounds required to fulfill the degree of damage in statistical manners. In this paper, we describe the basis for our design concepts reflected in the model to simulate the weapon effectiveness of top-attack smart munitions and provide simulation results for an example case.

Weapon target assignment problem is an essential technology for automating the operator's rapid decision-making support in a battlefield situation. Weapon target assignment problem is a kind of the optimization problem that can build up an objective function by maximizing the number of threat target destructed or maximizing the survival rate of the protected assets. Weapon target assignment problem is known as the NP-Complete, and various studies have been conducted on it. Among them, a greedy heuristic algorithm which guarantees (1-1/e) approximation has been considered a very practical method in order to enhance the applicability of the real weapon system. In this paper, we formulated the weapon target assignment problem for supporting decision-making at the level of artillery. The lazy strategy based on hierarchical structure is proposed to accelerate the greedy algorithm. By experimental results, we show that our algorithm is more efficient in processing time and support the same level of the objective function value with the basic greedy algorithm.

한국 육군은 K-9자주포용 탄약보급 장비로 K-10 탄약운반 장갑차를 운용하고 있으며, K-55 자주포용 탄약운반 장갑차의 전력화를 검토하고 있다. K-55용 탄약운반 장갑차는 현재 시제장비로 개발 된 상태로, 이 장비의 전력화 여부 및 소요대수를 결정하기 위해서는 사전에 이 장비의 운용효과를 분석할 필요가 있다. 이에 본 연구에서는 시뮬레이션을 이용하여 K-55용 탄약 운반장갑차의 운용효과를 제시하였다. 시뮬레이션 모델은 육군의 화포 편성 및 기타 포병무기체계 작전계획 분석 등을 위해 사용되는 워게임 모델인 화력운용분석모델을 활용하였다. 화력운용분석모델 모의결과에 따른 K-55 자주포용 탄약운반차의 운용효과는 탄약운반장갑차의 전력화 여부에 대한 의사 결정에 활용할 수 있을 것이라 판단된다.

We focus on the Real time Fire Scheduling Problem (RFSP), the problem of determining the sequence of targets to be fired at, for the objective of minimizing threatening probability to achieve tactical goals. In this paper, we assume that there are m available weapons to fire at n targets (> m) and the weapons are already allocated to targets. One weapon or multiple weapons can fire at one target and these fire operations should start simultaneously while the finish time of them may be different. We suggest mathematical modeling for RFSP and several heuristic algorithms. Computational experiments are performed on randomly generated test problems and results show that the suggested algorithms outperform the firing method which is generally adopted in the field artillery.

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.

This paper represents how a muzzle brake affects the dynamic characteristics of the recoil system. A muzzle brake is a device attached to the muzzle for the express purpose of diverting the propellant gas stream from its original path, thereby creating a foreward thrust on the recoiling gun which is in opposition to its rearward motion. In order to obtain the full advantage of a muzzle brake, it is necessary that the recoil system of a gun be designed for the purpose.
