The threats around Korea Peninsula have been dramatically increased because North Korea is developing the Nuclear ballistic missile, Submarine launched ballistic missile(SLBM), and many kinds of weapons for sudden provocations. Therefore, ROK navy needs the cutting-edge warship combat systems in order to defeat the enemy threats effectively in the sea. The paper analyzes current warship combat system acquisition process and studies US navy and other advanced countries acquisition process and their contraction trends. After that, the paper proposes the optimal acquisition process of warship combat system for the ROK navy based on our current situation and other advanced countries acquisition trends. The paper will dedicate the next generation warship combat system acquisition process.

In next war, it will be expected that some requirement such as information acquisition, battlefield surveillance and control, increased power projection, precision attack by guided missile and electronic warfare may have special importance. The use of robot weapon system by Airforce will make up for some weak points of man based weapon system that Airforce currently has. And Airforce man/robot combined air vehicle weapon system can extend military operational theater and give its flexibility in next war where power, mobility and information should be all-in-one for military purpose.

Cost estimates are necessary for government acquisition program to support decisions about funding, to develop annual budget requests and to validate resource requirements at key decision points. Many researches have been done about cost estimating technique recently. Parametric cost estimating models based on CERs(Cost Estimating Relationships) have been mainly used using regression method with historical data. However, there are many restrictions in developing Korean version CERs because the number of data points are too small. Specially, data collection and data management system are unstable in Korean defense environment, when developing CERs. In this research, we analyzed the historical data, and found some cost drivers in guided weapon system area. We developed the Acquisition Unit Cost CER using the regression to remove multicollinearity in the historical data. So we could overcome the restriction of the insufficient sample number. This research as a first attempt is meaningful in terms of obtaining our own Acquisition Unit Cost CER using historical cost and physical characteristic in Korean development environment.

Currently, cost estimation is very important to the government acquisition programs to support decisions about funding and to evaluate resource requirement as key decision points. Parametric cost estimating models have been used extensively to obtain appropriate cost estimates in early acquisition phase. However, they have many restrictions to ensure the cost estimating result in Korean defense environment because they are developed in the U.S.A. environment. In order to obtain a good R&D cost estimate, developing our own CERs (Cost Estimation Relationships) using historical R&D data is essential. Nevertheless, there has been little research to develop our own CERs. In this research, we established a CER development process and found some cost drivers in the historical movement weapon system R&D data. The R&D CER is developed using the PCR(Principle Component Regression) method to remove multicollinearity among data and to overcome the restriction of the insufficient number of sample. At least, this research is meaningful as a first attempt in terms of defining the CER development process and obtaining our own R&D CER based on the historical data in Korean weapon system R&D environment.

In general, weapon systems require very high reliability. Recently Korean defense reliability technologies growth rapidly. However, there are some matters of reform in reliability management, reliability assurance, and defense acquisition environment, etc. In this paper, we propose the reliability development plan for Korean defense system as follows; 1) reliability improvement programs for each acquisition stages, 2) reliability improvement methods for logistics support, 3) reliability improvement programs for developers and manufacturers, 4) reform matters for the defense acquisition law, 6) establishment of defense reliability assessment center and defense reliability committee.

In this paper, we consider an economic order quantity(EOQ) and an optimal discount pricing policy for the monopsony related to the weapon system acquisition. In the monopsony case, a buyer wishes to maximize the profit. However, a seller wants to minimize the total inventory related cost since a buyer can determine the purchase price for the product. We develop a generalized version of EOQ model for the monopsony, including one seller-one buyer model and two seller-one buyer model. A model of buyer reaction to any given pricing scheme is developed to show that there exits a unified pricing policy which motivates the buyer to increase its ordering quantity per order, thereby reducing the joint(buyer and seller) ordering and holding costs in the system.

In Korea weapon system acquisition processes, it's required a cost estimation report obtained from a commercial cost model. The PRICE model is generally used as a cost estimation model in Korea. However, the model uses American historical R&D data and it's output cost component is different from our cost component of defense accounting system. Also, we found that estimating results show about 10% of difference when we comparing with actual costs in 44 finished weapon acquisition projects. There are some limitations in calibration to increase an accuracy of the PRICE model because it's difficult obtain good real input data, detailed cost and technical data in low level WBS. So, only 8% of the defense R&D projects are calibrated and validation of calibration results is more difficult. Therefore, we studied the standard calibration process and performed the calibration about the MCPLXS/E parameters of the PRICE model based on actual cost data. In order to obtain a good calculation result, we collected the actual material costs from the defense industry companies. Our results can be used for an reference in similar weapon system R&D and production cost estimation cases.

경쟁이 심화되는 글로벌 방산수출환경은 다양한 비정형적 데이터의 체계적인 분석을 통해 수출목표국가에 대한 수출유망분야를 선정한 후 수출방향에 대한 전략적 맞춤화가 필요한 시점이다. 이에 본 연구는 방산수출품목 시장확대를 목적으로 수출목표국가를 독일, 영국, 프랑스로 선정하고 해당국가별 향후 10년간 무기체계 획득계획에 대한 비정형 예측 데이터를 확보하고자 하였다. 이후 텍스트 마이닝 분석 중 TF-IDF 기법을 활용하여 3개국의 데에터에서 자주 등장하는 핵심어를 도출하고자 하였다. 분석결과, 각 국의 주요 획득사업에 대한 핵심어를 도출할 수 있었고 이를 토대로 3국의 공통적 획득계획이 있는 핵심어를 유사한 의미로 분류하여 현 시점의 방산수출에 대한 유망수출품목을 발굴할 수 있었다.

The Israeli military's track record boasts victories in four Middle East wars and numerous counter-terrorism battles. This can be attributed to the implementation of a flexible defense acquisition system, allowing for the rapid acquisition of cutting-edge weaponry in response to ever-changing enemy vulnerabilities. If Korea were to adopt the defense acquisition system employed by the Israeli Defense Forces (IDF) it has the potential to transform into a small but strong country, mirroring the accomplishments of the IDF.

무기체계의 성능을 뜻하는 작전운용성능(Required Operational Capability)은 신규 무기체계의 소요 결정 시 함께 결정되며, 무기체계의 획득부터 전술적인 운용에 이르기까지 결정적인 영향을 미치기 때문에 이를 정의하는 것은 매우 중요한 일이다. 본 연구에서는 새롭게 개발되는 무기체계인 관측포탄의 ROC를 검증하기 위한 시뮬레이션 기반의 방법론을 제안한다. 이를 위해, ROC를 구성하는 무기체계의 주요 성능과 무기체계의 성능에 영향을 미치는 외부환경요인을 입력값으로 하고, 작전운용효과를 결과값으로 출력하는 이산사건 시뮬레이션 모델을 제안한다. 시뮬레이션 모델을 구현하는데 필요한 모의논리를 설명하고 민감도 분석 등 다양한 시뮬레이션 결과를 활용하여 ROC를 검증할 수 있는 방법에 대해 설명한다. 본 연구는 관측포탄과 같이 유사무기체계가 없고 군의 분석모델을 직접적으로 활용하기 어려운 무기체계의 ROC를 분석하고 작전효과를 예측할 수 있는 방법론으로 활용이 가능할 것이다.
