This paper deals with the attrition rate of major facility such as a particular building that is one of the most important target in the war time. In order to estimate the attrition rate, we use JAWS, WinJMEM which are programed by JTCG/ME of AMSAA and spreadsheet package which is able to assist the limitation of those programs and calculate all the procedure of this computation. This method uses the effectiveness index(El) which indicates the numerical measure of the effectiveness of a given weapon of a given target. The range error probable(REP) and the deflection error probable(DEP) in the ground plane also should be used. Those mean the measure of delivery accuracy of the weapon system. In this paper, it is improved that the El can be obtained from the regression analysis using the weight of the warhead explosive as the independent variable. It implies that we are able to obtain the El and the conditional probability of damage of the enemy weapon. After that, the single-sortie probability of damage can be computed using WinJMEM or another assistant program such as the spreadsheet package which shows the result immediately.

The expiration date of high energetic materials(HEM), such as HMX, RDX, TNT, is important. If the expiration date is violated, the expected specification of HEM would not be satisfied which may cause a different conclusion in an urgent situation. As a result, this HEM should maintain fresh conditions which cause the accumulation of waste HEM. If HEM is landfilled during demilitarization, the impact on living organizations is serious. Additionally, landfilling HEM has a possibility of explosion. In this research, the process flow diagram of the demilitarization gas treatment process was simulated while satisfying the law of the environment in Korea. After validation of simulation, it was optimized thermodynamically using Heat Exchanger Network Synthesis(HENs). This study is expected to enhance the energy efficiency of the original facility by suggesting developed designs. This research was supported by Agency of Defense Development NE32 Korea.

The primary purpose of this study was to analyze assessment factors by identifying and prioritizing live fire shooting area requirements using the AHP (Analytic Hierarchy Process) technique. Derived assessment factors for candidate sites were divided into six categories. Of these, four categories (base-to-range distance, weapon danger area, range terrain, and size) were in the realm of physical geography while the remaining two (land use and proximity to habitation) fell under the general heading of human geography. A case study was also conducted to select several alternative firing ranges using derived factors. The optimal location was analyzed by evaluating the candidate site using each assessment factor. As a result, it was found that assessment factors applying to GIS (Geographic Information System) were able to effectively analyze a suitable location for relocation of the focal training facility, taking into consideration public-safety issues, training requirements, and residents' past and likely future complaints. Through this process, it can prevent the waste of time and effort in determining an optimal location for a live fire shooing range.

The management of defects in barracks facilities is carried out in such a way that defects found by the facility's manager are listed and requested to be repaired by the contractor. However, the standards and methods for the inspection of defects in the management of these defects are not specified in detail, so it is difficult to check the defects in detail. In response, the study first analyzed the current status of the number of defects that occurred in 2021 at official residences and barracks of certain units. As a result of the analysis, the number of defects that were not taken care of and that were not taken until the previous month was more than 10 cases on average per month. In order to reduce the number of such defects, major improvements in the field, timing, and safety inspection were found after the inspection of the military's facilities and safety, and the analysis of the manual of maintenance management. In addition, items for improvement of the checklist were derived through an analysis of the repair of defects caused by the unit's official residence and a total of 10 barracks facilities. Based on this, a checklist was proposed to manage defects in barracks facilities through interviews with military facility managers.

최근 군수품에 대한 개발 및 생산이 날로 증가하고 있다. 그러므로 생산된 군수품에 대한 제한된 자원과 인력에 맞는 효율적인 품질 보증 방안이 요구되는 실정이다. 군수품은 특징적으로 사업 계약 단위로 개발 및 생산이 진행된다. 더불어 계약별로 사업 관리 및 품질 보증이 이루어진다. 이러한 이유로 하나의 생산 업체에서 여러 계약이 체결되고 유사한 제품들이 생산되는 경우가 많다. 사업 및 품질 보증도 많은 인력과 노력이 필요한 실정이다. 하나의 업체에서 여러 유사한 동종 제품을 생산 하는 경우에는 좀 더 효율적인 관리 방안이 요구된다. 이런 문제점을 알아보고 해결 방안을 찾아보았다. 하나의 업체에서 수행하는 군수품 계약 형태와 생산되는 제품의 특성을 분석하고. 그 결과를 기반으로 계약별 관리 방법에서 업체별 즉, 사업장별로 통합하여 관리 할 수 있는 방안을 제시해 보았다. 한 엔진 제작 전문 업체에 그 방안을 적용하여 통합 관리 방안을 검증해 보고 효과를 확인하였다. 사업장 단위 품질 보증 효과는 기존 계약 단위의 관리 방안에 비해 관리 인력 운영 측면에 상당한 절감 효과와 사업별 품질 보증 활동 결과를 타사업과 비교 검토하여 장점을 전 사업에 확대 적용 가능하여 품질 안정화 및 개선 효과를 만들었다.

The purpose of this paper is to explore the relationship between the number of relocation and volition of soldier's service based on system thinking perspective using a causal loop analysis. Research adopting system dynamics concerning on the volition of soldier's service and relocation has not been studied yet. Causal loops are analyzed and evaluated by focusing on soldier's military performance, stress of family members and family members' welfare service. Result of this study is that soldier's periodical movement is indispensable factor maintaining military life. Most of the married soldier's life conditions are worse than ordinary people. As the number of relocation is increasing family of soldier's stress is increased by anxiety for welfare conditions is supposed to relocate. The number of movement to another place of soldier's children is more than two times and the result of learning achievement is worse than ordinary students. This kind of stress can influence the married soldier's military performance and stress. So the welfare service should be expanded to an official residence, education, facility, district network service and so on.

As the organizational size of a military service or business increases and its management becomes complex, the success in its management depends less on static type of management but more on careful, dynamic type of management. In this thesis, an operations research technique is applied to the problems of determining optimal air traffic control rule and of optimal capacity of air base for a military air base. An airport runway is regarded as the service facility in a queueing mechanism, used by landing, low approach, and departing aircraft. The usual order of service gives priority different classes of aircraft such as landings, departures, and low approaches; here service disciplines are considered assigning priorities to different classes of aricraft grouped according to required runway time. Several such priority rules are compared by means of a steady-state queueing model with non-preemptive priorities. From the survey conducted for the thesis development, it was found that the flight pattern such as departure, law approach, and landing within a control zone, follows a Poisson distribution and the service time follows an Erlang distribution. In the problem of choosing the optimal air traffic control rule, the control rule of giving service priority to the aircraft with a minimum average waiting cost, regardless of flight patterns, was found to be the optimal one. Through a simulation with data collected at K-O O Air Base, the optimal take-off interval and the optimal capacity of aircraft to be employed were determined.

The objective of this study is to provide basic information for planning and practicing social welfare services for married nurse officers serving in the Korean military. For such a purpose, this study identifies the difficulties which married nurse officers have faced and the necessary services which are supposed to alleviate them. The data were collected by sending a questionnaire to 114 married nurse officers from July 16 to August 10, 2001. The results of this study are as follows: First, the married nurse officers were relatively dissatisfied with such domains as child care and education, health, and housing. And among the thirty-four problems, the married nurse officers expressed the most serious dissatisfaction with the difficulty in attending the events held in child's school, lack of children's dormitory run by the military, difficulty in adjusting to the school due to frequent house-moving, and limited access to dental care. Second, the married nurse officers needed services in domains such as housing, child care and education, and health. Specifically, they wanted the military-run housing, child care facility within military hospitals, maternity leave for child care and education, extension of risk allowances, and support for BOQ. Third, with regard to the seriousness of problems as well as the priority of services, the married nurse officers gave higher priority to such domains as child care and education, health, and housing. These results indicate that married nurse officers were to the largest extent concerned with these three domains and that they had the urgent need for services relevant to those domains. The importance of routine need assessments as well as solutions to the family-related problems for married nurse officers is therefore suggested in this study.
