In this paper, we have proposed a design method for standardization of weapon information exchange between a weapon control computer of guided missile system and a high echelon command and control system. Because the weapon control computer based on diverse combat platforms is operated with several kinds of a high echelon system, it is necessary to provide a standardized design method for weapon information exchange between mutual system. In fact, it is possible to standardize a interface design specification of weapon information message because weapon information message is closely related to standard tactical data link message. It is essential that the interface design specification of weapon information is submitted to that of tactical data link information. It seems that this interface design specification is very useful in development process of the future weapon system.

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.

Purpose: There is a difficulty in Environmental Stress Screening (ESS) test design for weapon system's electrical/electronic components/products in small and medium-sized enterprises. To overcome this difficulty, I propose an easy ESS test design approach algorithm that is optimized with only one environment tolerance design information parameter (${\Delta}T$). Methods: To propose the mass production weapon system ESS test design for cost-effective optimization, I define an optimum cost-effective mathematical model ESS test algorithm model based on modified MIL-HDBK-344, MIL-HDBK-2164 and DTIC Technical Report 2477. Results: I clearly confirmed and obtained the quantitative data of ESS effectiveness and cost optimization along our ESS test design algorithm through the practical case. I will expect that proposed ESS test method is used for ESS process improvement activity and cost cutting of mass production weapon system manufacturing cost in small and medium-sized enterprises. Conclusion: In order to compare the effectiveness of the proposed algorithm, I compared the effectiveness of the existing ESS test and the proposed algorithm ESS test based on the existing weapon system circuit card assembly for signal processing. As a result of the comparison, it was confirmed that the test time was reduced from 573.0 minutes to 517.2minutes (9.74% less than existing test time).

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.

In this paper, we have proposed a methodology which can make effective test for system integration of complex guided missile system. System integration test play a significant role in the development of weapon system, providing the means to detect and isolate faults on first linkage between sub-systems. Integration tests for domestic weapon system has executed not a technology-intensive method based on tool but labor-intensive method based on experience. Higher cost, longer period, and more resource are required to execute system integration test for complex guided missile system comparing with past weapon systems, because recently weapon systems have more complex and more networked functions. Because the proposed design method for system integration test decreases number of test case, it lead to a decrease of cost, period, and resource for integration test of weapon system. The proposed configuration for system integration test will ensure reliability through detection and isolation of fault on linkage between sub-systems.

The Systems Engineering method is increasingly recognized as a central in the Acquisition of Weapon Systems in South Korea. Because of these trends, issues concerned with improving weapon system design are increasingly raised. This paper presents a development of Operational Mode Summary/Mission Profile (OMS/MP) in terms of Weapon Systems Acquisition for application to Systems Engineering method. For a systematic approach, a precise concept of OMS/MP is derived by analyzing the concept of conventional OMS/MP. This paper reviews the results of a series of previously reported examples aiming to develop the OMS/MP of a weapon system. Based on this, the limitations of the conventional OSM/MP applications are investigated. And these limitations can be resolved by the Fundamentals of Systems Engineering. Finally, the OMS/MP framework based on the Fundamentals of Systems Engineering has been proposed and is successfully implemented for the Harbor Underwater Surveillance System.

Test and evaluation of weapon system is an important task to evaluate the performance of overseas weapon system purchasing project. Especially, quantitative evaluation of performances is hardly completed in defense projects where multiple criteria are conflicted each other. In order to solve this problem, we apply Axiomatic Design (AD) and Inner Dependence AHP method. First, finite functional requirements (FRs) are categorized in hierarchy structure by selecting proper design parameters (DPs) to implement their corresponding FRs. If there are no ways to select DPs when design is coupled between FRs and DPs, then inner dependence is allowed to overcome the strict rule of independence in AHP. Second, the weights of DPs are calculated by applying both Inner Dependence AHP method for coupled design and normal AHP method for uncoupled or decoupled design. Finally, information axiom of AD is applied to the proposed weapon systems by calculating information contents for all parameters. Weapon system with minimum sum of information contents is considered as the best solution. The proposed method in this study should be used in multiple criteria decision making problems involving various conflicting criteria.

무장통제 소프트웨어는 무장체계와 연동하여 함정 전투체계 내 무장 운용을 지원하는 기능을 수행한다. 무장통제 소프트웨어는 무장체계에 의존적이므로 연동 정보 변화에 따라 소프트웨어 수정이 필연적으로 이뤄지는 특성을 가진다. 소프트웨어의 수정은 신뢰성 시험과 같은 검증 단계를 반드시 거쳐야 하므로 개발 비용의 상승을 초래한다. 본 논문에서는 기존 무장통제 소프트웨어의 수정 요소를 최소화하기 위해 무장통제 소프트웨어 표준 아키텍처를 설계하였다. 연동 정보 관리를 위해 휘처 모델(Feature Model)로 공통요소와 가변요소를 구분하였고 디자인패턴 중 전략 패턴(Strategy Pattern)을 적용하여 소프트웨어 구조를 개선하였다. 소프트웨어 평가 실험을 통해 제안한 아키텍처가 기존 무장통제 소프트웨어보다 개발 비용이 감소하고 변경용이성과 재사용성이 향상된 것을 확인하였다.

In general, weapon system design/configuration data consist of system structure information which is linked to Part information, documents and drawings. For configuration management, version and revision control are necessary and access control of users to information should be managed for information security. Configuration data of weapon systems have various kinds of different meta data which are contained in the structure as well as attributes of parts and documents information. If neutral types of meta data models be used for building configuration management system, they can be applied to many different kinds of weapon systems with a little customization. In this paper, five meta data models are supposed and implementation results of them by using CBD(component based design) methodology are presented.

지향성 에너지 무기는 순간적으로 집중된 에너지를 특정한 방향으로 방사하여 적 전자장비를 교란하거나 과부하를 초래하는 무기체계이다. 이러한 지향성 에너지 무기체계의 성능을 결정하고, 설계를 수행함에 있어 표적에 대한 효과 분석은 중요한 고려 요소 중 하나이다. 본 논문에서는 대표적인 지향성 에너지 무기체계인 공중방어체계에 대한 효과도를 분석하였다. 이를 위하여 고출력 원형편파 피드혼을 적용한 반사판 안테나를 설계하고, 거리 별 유효면적에 인가되는 출력밀도를 시뮬레이션 툴과 프리스 공식을 활용하여 분석하였다. 이를 통하여 안테나 시스템 설계에 대한 유효성을 검증하고, 표적에 대한 지향성 에너지 무기의 효과를 확인하였다.
