In principle, R&D of general weapons systems are led by companies or government-funded organizations. In terms of project execution, the defense R&D planning system was reorganized to conduct SE-based project management by integrating the naval ship project execution procedure into the general weapon system R&D procedure. The development progress was confirmed according to the guide for SE application of DAPA, and a technical review meeting was proposed to enter into the each next phase in the R&D process. This paper focuses on improvement for technical review in terms of technical management based on system engineering for R&D mounted weapon systems and the naval surface ship project in preliminary design and detailed design. So, the improvement direction for reviewing the entry criteria for the R&D weapons systems of the naval ship and mounted weapons is proposed.

Purpose: Recent weapon systems in defense have increased the complexity and importance of software when developing multifunctional equipment. In this study, we analyze the accuracy of the proposed software reliability model when applied to weapon systems. Methods: Determine the similarity between software reliability analysis results (prediction/estimation) utilizing data from developing weapon systems and system failures data during operation of weapon systems. Results: In case of a software reliability prediction model, the predicted failure rate was higher than the actual failure rate, and the estimation model was consistent with actual failure history data. Conclusion: The software prediction model needs to adjust the variables that are appropriate for the domestic weapon system environment. As the reliability of software is increasingly important in the defense industry, continuous efforts are needed to ensure accurate reliability analysis in the development of weapon systems.

This note suggests three approaches to improve reliability in developing weapon systems. The high complexity of the weapon systems make it hard to analyze and predict of those reliability. Current situations of the reliability have been reviewed in terms of logistics support analysis (LSA), warranty policy, maintenance and development. Three suggestions are notified to improve the reliability considering the complexity of the weapon systems.

The requirement verification is the integral part of the weapon system R&D to reduce cost and schedule. And, a systems engineering is an interdisciplinary engineering management process that evolves and verifies an integrated, life-cycle balanced set of system solutions that satisfy customer needs. Therefore, this study analyzes the national defense need and acquisition management process, investigates the systems engineering verification activity. Through the requirement verification example in terms of technical evaluation this study presented the requirement verification approach in the weapon system R&D.

State-of-the-art design S/W and other 3D systems are used for design and development of weapon system. It is possible to detect problems of design through 3D or VR(Virtual Reality) in advance, and then reduce the development cost by finding solutions before prototype production. Therefore, we can increase efficiency for supportability of weapon system. In this study, we first propose a design verification procedure. Then we verify design of weapon system, underwater guided weapon, as a case study. Finally, we suggest alternatives for underwater guided weapon under development with DMS(Digital Maintenance System) and ICIDO from the point of view of ILS(Integrated Logistics Support). Developed S/W, DMS, draws maintenance procedures for components. Commercial S/W, ICIDO, verifies cable maintainability.

The Core in Weapon system R&D is to realize the user required capabilities in limited schedule and cost. Therefore, the design of weapon system focuses to functional design for realization of requirement capabilities. However, the weapon system should not only basically bring the confidence to friendly forces bring fear to enemy forces to maximize the operational effectiveness of weapon systems and we consider the exterior design as the important factor to compete with foreign systems in international defense market besides capabilities and cost. For that reason, we made study case about the visual design decision process applied to the LVT(light tactical vehicle) project which was recent successful deployment among the many R&D projects of auto industry. Based on this case, this study suggests the necessity of the exterior design decision process the maneuver weapon system is developed.

무기체계는 기술의 발달로 인하여 급속도로 발전하고 있다. 이러한 발전덕분에 과거 무기체계에서 보지 못했던 고가의 첨단 전자장비들이 포함된 무기체계가 등장하게 되었다. 더불어, 고도의 기술이 적용된 무기체계의 운영 및 유지보수를 위한 장비유지예산 또한 증가되고 있다. 그러나 장비유지예산은 장비자산대비 그 비율이 감소추세에 있어, 효율적인 무기체계 운영에 어려움이 초래되고 있다. 이처럼 고비용 환경이 되고 있는 국방경영 및 감소되고 있는 장비유지예산을 고려하는 연구가 필요하다. 본 연구는 무기체계를 운영 및 유지보수 하는데 필요한 정비장비에 초점을 두고 있다. 최신 무기체계는 계측장비와 같은 정비장비를 활용하여 무기체계의 정렬 및 검교정 절차를 수행 후, 적정한 무기 성능이 유효하다고 볼 수 있다. 이러한 계측장비는 주기적으로 업체 외주정비(검교정 절차)를 하여 계측장비 자체의 정렬 및 상태 이상 유무를 확인해야 한다. 일반적으로 계측장비는 신뢰성이 입증된 해외업체의 계측장비를 구매하게 되고, 이러한 계측장비는 주기적으로 해외 외주정비를 받을 수밖에 없게 된다. 즉, 정비장비가 해외 외주정비를 진행하는 동안, 해당 무기체계는 성능에 대해 신뢰할 수 없으며 불가용 상태라고 볼 수 있다. 본 연구의 목적은 정비장비의 해외 외주정비로 인해 발생하는 무기체계의 손실비용과 정비장비의 구매 비용을 비교하여, 적절한 정비장비의 구매 대수를 제시하고자 한다. 본 연구의 결과가 효율적 작전 수행 보장에 기여할 것으로 판단되며, 전력 공백 문제를 해결 가능한 방안이 될 것이다.

Quality management is essential to achieve the desired quality throughout a program. Especially in phase of research and development(R&D) of a program, that is an effective and efficient way to achieve the quality goals and improve the quality of a program in total life cycles. For applying the quality management to a R&D program, characteristics of the program should be considered in various aspects. In this study, the characteristics of developments of defense weapon systems were analyzed and the meaning of quality in that field was defined. And then, application methods of the quality management were established and the quality management model with four view points(external, organization, programs, practices) was proposed. In addition, detailed tasks of the quality management activities were described and some examples of applying the model were introduced.

무기체계 평가를 위한 시험업무는 무기체계 획득 또는 개발 전 수명주기 동안 수행되는 프로세스 중 가장 중요한 프로세스 중 하나이다. 무기체계 개발완료 전, 무기체계에 대한 적절한 평가시험을 수행할 경우, 무기체계 개발과정 중 발생할 수 있는 결함을 조기에 발견함으로써, 개발위험과 소요비용을 크게 감소시킬 수 있다. 본 연구에서는 연초 계획된 무기체계 평가시험 물량을 연말까지 달성할 확률이 얼마나 되는지 파악하기 위한 방법으로 몬테카를로 시뮬레이션 기반의 확률적 예측 기법을 제안하였다. 또한 연말 달성 확률 예측 결과를 바탕으로 시험일정 수립 담당자가 월간 시험 수행건수를 조정하기 위한 의사결정에 도움을 줄 수 있는 정량적 관리방안을 제시하였다. 상기와 같이 제안된 예측 및 관리 기법은 국방과학연구소 제 8기술연구본부의 실제 시험계획 및 실적 데이터에 적용하였으며, 그 적용 결과를 고찰하였다.

Recently, the use of domestic products securing domestic technology is encouraged, because of export restrictions of the countries or DMSMS(diminishing manufacturing sources and shortages). Domestic weapon systems are actively focused on the parts localization process of R&D projects based on Systems Engineering. However, it is the only way to do technical review for Systems Engineering process up to now. There is a case of application in Localization with Systems Engineering process, but the SE activity is not enough. This study is how to apply Systems Engineering process to Localization effectively based on real cases.
