Artillery fire power due to effectiveness which is hard to predict well-planned and surprising attack can give a fear and shock to the personnel and is a very core weapon system and takes a critical role in wartime. Therefore in order to maximize operational effectiveness, Army required protecting artillery and takes a quick attack action through rapid construction of artillery's positions. The artillery use artillery's position to prevent exposure by moving to other position frequently. They have to move and construct at new artillery's positions quickly against exposing existed place by foe's recognition. These positions should be built by not manpower but engineering construction equipment. Because artillery positions have to protect human and artillery equipment well and build quickly. Military engineering battalion have lots of construction equipment which include excavator, loader, dozer, combat multi-purposed excavator, armored combat earthmover dump truck and so on. So they have to decide to optimal number of Team combining these equipments and determine construction sequence of artillery's position in operational plan. In this research, we propose to decide number of Team efficiently and allocate required construction's positions for each Team under constraints of limited equipments and time. To do so, we develop efficient heuristic method which can give near optimal solution and be applied to various situation including commander's intention, artillery position's priority or grouping etc. This heuristic can support quick and flexible construction plan of artillery positions not only for using various composition's equipment to organize Teams but also for changing quantity of positions.

In this paper, we deal with the vehicle routing problem that could establish operational plan of military engineer for survivability support of artillery position construction. We propose VRPTW(vehicle routing problem with time-window) model of special form that considered service level to reflect the characteristics of military operations rather than the logic of economic efficiencies in the objective function. Furthermore we suggest modified particle swarm optimization algorithm for service based vehicle routing problem solution that can be possible to search in complicated and uncertain area and control relation softly between global and local search.

This paper aims to examine the constructional background and process of the Japanese military installations of Oiyang-po(外洋浦), especially based on the military secret documents. Furthermore, it aims to analyze the characteristics of the remains. The results are as follow; 1) The number of the Japanese military secret documents concerning with the installations of Oiyang-po, summed up to 33s. Especially, 14 documents about the expropriation of the lands and houses, and the constructions of the artillery position are reserved in "Mildae-ilgi"(密大日記)written from 1893 to 1942. 2) Imperialist Japan constructed firstly the military installations of Oiyang-po against the Russo-Japanese War. After the moving of the artillery headquarters into Masan in 1911, these installations had been maintained for the defense of Busan and Jinhae Bays. 3) As soon as 1904, the lands and houses of Oiyang-po were forcibly expropriated according to (韓日議定書). The Korean Government payed the expropriation prices to the dwellers. But the amount of money were too small and were lately payed. Moreover the dwellers' fishery right were never recompensed. 4) In 1904, the artillery headquarters and position were constructed by the 3rd Chookseong-dan(築城團) under the command of Matsui, a military engineer officer. The executional constructions were accomplished by the Japanese construction contractors. 5) After the moving of the artillery headquarters into Masan in 1911, the 3rd Chookseong-dan had usually repaired and consolidated the explosive warehouses and artillery facilities. 6) The artillery position constructed with the thick concrete walls was located at the foot of the mountain in back. It's plan was similar to the rectangular shape. It reserved six 280㎜ howizers and several explosive warehouses. 7) The reserve funds and arsenal funds were used for the constructions. And the items of expenses such as the establishments of the electric lights and communication networks, and the repairs of the explosive warehouses were mainly recoded in "Mildae-ilgi".

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.

육군의 공병은 여러 장비를 이용하여 다양한 작전을 수행 중이며, 대표적인 군사작전 분야로는 포병 진지구축지원이 있다. 포병은 아군의 후방에서 화력으로 적의 중심을 타격하는 임무를 수행하며, 이때 사격 위치 노출 방지를 위해 한 진지에서 여러 차례 사격 후 진지를 반드시 이동해야 함에 따라 제한된 수의 장비를 효율적으로 운용하여 다수의 진지를 신속히 구축하는 것이 필요하다. 본 연구에서는 진지 구축시 제약조건을 반영하여, 공병장비-팀(작업)-진지간 최적할당이 가능한 수리모형과 휴리스틱 알고리즘을 제시하고 이에 대한 실험결과를 제시하고자 한다. 본 논문에서 제안한 최적화 수리모형은 작은 크기의 문제에서는 최적해를 도출하나, 실제 공병대대 및 여단 규모의 장비배치 문제에서는 최적해 도출에 장시간이 소요되는 한계가 존재함에 따라, 수리모형 기반의 휴리스틱 역시 제안하였다. 해당 휴리스틱은 1단계에서 수리 모형의 일부 변수의 정수제약 조건을 완화하고 할당에 대한 최적해를 구하고, 해당 해를 원 수리모형에 추가하여 최종 해를 구하는 형태로 설계하였다. 이러한 휴리스틱은 최적해의 도출은 보장하지는 못하나 문제의 크기가 커져도 빠른 시간에 해를 도출할 수 있었다.

This paper aims to examine the constructional background and process of the Japanese military installations of Jisim-do, especially based on the military secret documents. Furthermore, it aims to analyze the characteristics of the remains. First, the study looked into the procedure of forcible occupation by Japan, involving the background of the designation and forcible accommodation of military reservations, and forced eviction by the purchase of land. Second, the study identified the background of construction, purpose, and construction period of each battery built throughout the 'Fort maintenance period' according to changes in international situations. Third, it is the 'Chukseongbu' that supervised the construction of fortresses. Fourth, the study considered a series of arrangement processes in which Jisim-do became a fortresses through "Yukgunsungdae-ilgi", a military operations report for the Japanese army. Through this, it discovered a clear construction process, construction details, and the supply for Jisim-do. The study was also able to reveal the meticulousness in constructing firm facilities more promptly from the 'design tactics'.

The future combat system is likely to be studied and developed in terms of enhancing both firepower and mobility simultaneously. Increased firepower often necessitates a heavier firing system. In return, the body of the vehicle needs to be light-weight in order to improve the mobility of the whole system. For this reason, in the areas of weapons systems such as the tank and self-propelled artillery, a number of studies attempting to develop designs that reduce recoil force against the body of the vehicle are being conducted. The current study proposes a tank construction that has a mass-spring-damper system with two degrees of freedom. A tank structure mounted with a specific soft recoil system that was implemented using a soft recoil technique and another tank structure based on a general recoil technique were compared to each other in order to analyze the recoil forces, the displacements of recoil, and the firing intervals when they were firing. MATLAB-Simulink was used as a simulating tool. In addition, the relationship between the movement of the recoil parts and the positions of the recoil latches in each of the two structures were analyzed. The recoil impact power, recoil displacement, firing interval, and so on were derived as functional formulas based on the position of the recoil latch.
