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.

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.

The management systems of defense projects need to be well-maintained because of huge cost and long-terms of acquisition & operation in conducting defense acquisition. In this paper, we use a structural equation model(SEM) to develop an project management index(PMI) for effective defense project. The concept of a customer satisfaction index is used to assess the PMI for strategic improvement plans for various characteristics of project management. It is expected that our model can be used to evaluate and improve the project management capability of defense acquisition.

최근 방위력 증강을 위해 대규모 무기체계 획득사업을 추진하면서 큰 폭의 국방예산 증액이 예상되고 있으며, 이러한 무기체계 획득에 필요한 재원 확보를 위해 국방예산의 효율화 필요성이 제기되고 있다. 또한 국방획득사업의 예산 절감뿐만 아니라 해외 수출가능성, 고용창출 효과 등 국내 경제에 영향을 미치는 경제성 요소에 대한 관심이 높아지고 있다. 이러한 요구에 부응하기 위해 국방획득사업 추진 시 비용편익 분석, 경제적 파급효과 등을 고려한 경제성 분석을 검토하고 있으나, 아직까지 국방획득사업의 특성을 고려한 경제성 분석 방법론에 대한 연구는 초기 단계인 실정이다. 본 연구에서는 국방획득사업의 경제성 분석을 위한 방법론을 제안하고, 국지도발에 대비해서 추진하고 있는 ${\bigcirc}{\bigcirc}$유도무기에 대한 경제성 분석 실증연구를 수행하였다. 본 연구에서 제안한 경제성 분석 방법은 그동안 다수의 무기체계 획득사업에서 수행해왔던 비용 대 효과분석을 보다 일반적인 비용편익 분석방법과 연계하여 그 분석 결과를 제공함으로써, 향후 보다 포괄적이고 신뢰성 있는 무기체계 획득사업 경제성 분석 확립에 본 연구가 개념적 방법론적으로 다소간 기여할 수 있을 것으로 판단된다.

The term of defense procurement is used indifferently from defence acquisition. It consists of two sectors : domestic defense procurement and foreign defense procurement. For efficient and transparent defense procurement, Defence Acquisition Program Law in Korea suggests some principles including the purchase of domestically manufactured munitions in the first instance, and the Defense Acquisition Program Administration(DAPA)'s direct procurement of munitions, etc. By reviewing the characteristics, process, current situation and model contracts of defense procurement, it is found that domestic procurement contracts only propose the legal approach instead of arbitration and foreign procurement contracts suggest confusedly both the legal approach and arbitration for amicable disputes settlement. Therefore, it is quite recommended for arbitration organizations such as the Korean Commercial Arbitration Board(KCAB), the Korean Arbitrators Association(KAA), and the Korean Association of Arbitration Studies(KAAS) to foster a variety of strong awareness campaign, education and consulting programs, etc. for the popular use of arbitration clause. It will contribute to settle any disputes and controversies between the parties more speedy, economically and rationally, thereby reducing the costs, time and pains for solving them.

In the defense acquisition, a company's goal is to maximize profits, and the government's goal is to allocate budgets efficiently. Each year, the government estimates the ratio of indirect cost sector to defense companies, and estimates the ratio to be applied when calculating cost of the defense articles next year. The defense industry environment is changing rapidly, due to the increasing trend of defense acquisition budgets, the advancement of weapon systems, the effects of the 4th industrial revolution, and so on. As a result, the cost structure of defense companies is being diversifying. The purpose of this study is to find an alternative that can enhance the rationality of the current methodology for estimating the ratio of indirect cost sector of defense companies. To do this, we conducted data analysis using the R language on the cost data of defense companies over the past six years in the Defense Integrated Cost System. First, cluster analysis was conducted on the cost characteristics of defense companies. Then, we conducted a regression analysis of the relationship between direct and indirect costs for each cluster to see how much it reflects the cost structure of defense companies in direct labor cost-based indirect cost rate estimates. Lastly a new ratio prediction model based on regularized regression analysis was developed, applied to each cluster, and analyzed to compare performance with existing prediction models. According to the results of the study, it is necessary to estimate the indirect cost ratio based on the cost character group of defense companies, and the direct labor cost based indirect cost ratio estimation partially reflects the cost structure of defense companies. In addition, the current indirect cost ratio prediction method has a larger error than the new model.

국방무기체계획득사업 관리의 목적은 궁극적으로 요구된 성능, 예산, 전력화시기를 충족시키는 것이다. 2006년 출범한 방위사업청은 무기체계 획득사업을 효율적으로 수행하기 위해서 통합사업관리제를 도입하여, 방위력개선사업 관리를 위한 프로젝트 조직이 61개가 운영 중에 있다. 하지만 한국적인 국방획득환경에서의 프로젝트 관리 측면에서 실증적인 분석연구가 미흡한 것이 현실이다. 따라서 본 연구는 무기체계획득사업관리를 하나의 프로젝트로 인식하고, 프로젝트관리 연구에서 제시된 프로젝트 성공요인(CSF : Critical Success Factors)과 무기체계획득사업관리의 관계에 대해서 알아보았다. 연구 결과 전체적으로는 의사소통, 사용자 참여, 명확한 요구사항 변수가 프로젝트 성공에 영향을 주는 것으로 분석되었다. CSF 요소는 사업추진단계별, 사업의 특성, 규모에 따라서 프로젝트 성공에 미치는 영향이 각각 다르다는 것을 실증적으로 증명하였다. 이번 연구 결과를 통해서 통합사업관리팀이 무기체계획득사업 수행 시 사업 단계, 특성, 규모에 따라서 중점 관리 분야를 식별한 것이 이 논문의 의의라고 생각한다.

The contractor management for the effective defense project is essential factor in the modern defense acquisition task. The occurrence of unlawful company causes hastiness for project manager and setback to the deployment of defense weapon system. In this paper, we develop a prediction model for the effective defense project by using the discriminant analysis and analyse the variables that discriminate the unlawful company in many variables. It is expected that our model can be used to improve the project management capability of defense acquisition and contribute to the establishment of efficient procurement procedure through entry of the reliable defense manufacturer.

Exploiting models and simulations are encouraged among the defense acquisition society, as now enforced by the Defense Aquisition Program Administration's regulations. They are useful and, sometimes, inevitable especially in an earlier phase of system development. Computer-simulation-based experimentation technique for the system operational performance analysis for a torpedo defense system is introduced in this paper. Problem definition for the torpedo defense system analysis and engineering efforts for models and simulations development are presented here, including defining measures of performance and effectiveness for the torpedo defense system, conceptual modeling for torpedo engagement and defense simulation, design of experimentation, design of simulator and experimentor, and hardware and software implementation of an analysis support tool - a system operations demonstration and experimentation simulator.
