획득이란 군사임무 수행에 요구되는 무기체계나 서비스나 물자에 대하여 개념을 정립하고, 정책을 발전시키며 사업을 시작하여 무기체계를 개발하고, 생산하며 배치하고 운용하며 군수지원을 하고 개량하고 폐기하는 일련의 수명주기 활동에 필요한 업무를 통 털어 말한다. 따라서 획득관리란 획득이라는 개념에 대한 모든 관리활동을 말하며 획득관리를 담당하고 있는 획득요원들에 대한 교육훈련이 포함되고 나아가서는 국방중기계획을 수립하고 예산을 획득하는 기획관리업무를 지원하는 활동까지는 포함된다고 할 수 있다.

The development of weapon systems that look only be introduced as a huge budget directly related to combat rea diness. If we develop the expensive equipment it will not be the same state or have to wait a lot of time in mainten ance facilities for maintenance, which will have a profound impact on the exercise Efficiency. In order to solve this problem, the operation and use state of the weapon system requires effort to successfully p erform the duties held by the defined and assigned, Further analysis should be conducted RAM in order to reduce m aintenance manpower and logistic support costs. The role of business is to increase the RAM system reliability by L ee to Fig system failure rate from the development and maintenance, and reduced life cycle costs. Therefore, the present study was to determine the RAM to perform analysis procedures and methods and limita tions of each element, such as to maximize the effectiveness of comprehensive logistics support and help to study to become an effective logistics support.

An efficient R&D Methodology with minimized development period and cost needs to be developed due to advanced performance requirements of weapon systems. This will require the performance of logistics support analysis and design verification in the development stages of weapon systems through VR technology. VR technology has been applied to the Integrated Logistics Support (ILS) process as a part of collaborative system. In this study, we propose a development and application plan of ILS based on VR technology during the total life cycle of weapon systems. Moreover Digital Maintenance System (DMS) is introduced as a VR tool with key functions. finally, applications and improvement topics of DMS are suggested for use in ILS development.

Since the early 2000s, the United States has applied TLCSM to reduce life cycle costs while maintaining the weapons system's combat readiness. With the application of TLCSM, the ILS concept centered on the acquisition stage shifted to IPS, a concept that manages life cycle costs throughout the entire life cycle. In addition, LSAR for developing ILS has switched to LPD for developing IPS. In this study, LSAR in Korea and LPD in the United States were compared and analyzed, and policies necessary for the introduction of LPD in Korea were proposed.

Proposed in the paper is an agent based and object-oriented methodology to create a virtual logistics support system model. The proposed virtual logistics support system model consists of three types of objects: the logistics force agent model(static model), the military supplies transport manager model(function model), the military supplies state manager model(dynamic model). A logistic force agent model consists of two agent: main function agent and function agent. To improve the reusability and composability of a logistics force agent model, the function agent is designed to adapt to different logistics force agent configuration. A military supplies transport manager is agent that get information about supply route, make decisions based on decision variables, which are maintained by the military supplies state manager, and transport military supplies. A military supplies state manager is requested military supplies from logistics force agent, provide decision variables such as the capacity, order of priority. For the implementation of the proposed virtual logistics force agent model, this paper employs Discrete Event Systems Specification(DEVS) formalism.

It is very important for weapon systems to manage the logistic support for the better combat readiness. Therefore, in this paper we review the issues of logistic support and suggest alternatives to effectively manage the logistic support for weapon systems by using performance based logistics, especially during operations and support phase.

This paper describes the development and applications of maintainability simulation system based on virtual reality technology. The immersive type maintainability simulator using virtual reality is developed and assembly simulation using DELMIA software is conducted for an air-to-ground munition as an example. The simulation processes and result validate the feasibility and effectiveness of maintainability simulation system for logistic element development.

Purpose that studies the war history is to prevent the war in the advance through instruction that is gotten by understanding the past war and in case of emergency, it is to win victory in the war from the enemy by doing not commit a same mistake like the past war. For these reasons, many studies about the war history have proceeded continuously in domestic and outside the country, and those are being carried out in present. However, most of studies of the war history have been analyzed only on qualitative analysis. In this study, we want to suggest quantitative analysis method using simulation with qualitative analysis. As an example of study, we quantitatively analyzed the importance of logistics support on the Moscow expedition of Napoleon. Also, on the basis of this, we found failure factor of logistics support of Napoleon force and through this, deduced instruction. There is meaning that this paper suggested quantitative analytical method in terms of study of the war history with qualitative analytical method.

After patrol corvett Cheonan was hit and sank on duty, the Republic of Korea Navy has tried to install hybrid propulsion system on naval ship to reduce vibration and noise problems during navigation. The hybrid propulsion system has advantage that propulsion motor can be propelled in low speed operation of the vessel. This can be a better quietness than a mechanical propulsion system which consists of a conventional internal combustion engines. And more economical operation is possible by using a propulsion motor in a low speed operation where a fuel efficiency of the internal combustion engine is poor. In this paper, we set up virtual ship on the basis of a combat support ship in the Republic of Korea Navy, economically compared and analyzed fuel consumption between conventional and hybrid propulsion system. As a result, it was confirmed that the fuel efficiency of hybrid propulsion system which use electric motor had been relatively improved.
