In the modern warfield, as the defense systems has been digitalized, intelligent, and working with network, the importance of interoperability among the systems has been also increasing. KMND(Korean Ministry of National Defense) has developed and used the SITES(Systems Interoperability Test & Evaluation System) based on Korean LISI(Levels of Information Systems Interoperability). SITES had been developed in order to evaluate the interoperability among information systems from the viewpoint of technical attributes. In this paper, we propose the extended interoperability evaluation model which can be applied not only the information systems, but also the weapon systems. Moreover, the extended interoperability evaluation model also includes the consideration of non-technical attributes.

The improvement of the reliability of weapon systems and the reduction of the total life-cycle cost based on the improving of the DT&E system for Company Organized weapon systems research and development are urgently required. The major advanced countries operate test and evaluation centers for military (U.S.), manage a large scale organization of IPT personnel (England) or conduct management of DT&E through a third party organization (France). Based on a survey of experts, an improvement of the DT&E policy in terms of reliability and objectiveness is needed, and management through a third party national defense agency and civilian agency such as the Surion development case is required. In addition, although it appears that efficiency improves when management of DT&E is performed by national defence agencies rather than civilian agencies, it is necessary to proceed by selecting a civilian agency based on competition in the case that it is difficult to select a national defence agency.

It has been tested for SW reliability in order to prevent the SW error during the development of weapons systems. According to a recent report, defects such as memory leak, buffer overflow, and null deference occur usually in the development stage, but also in the mass production stage. Although it is intended to enhance the SW test and evaluation to prevent SW failures in the development stage, the non-functional problems like syntax errors are not completely revised due to the limitation of the schedule and costs. In addition, SW failure rate are usually fluctuated by the operational environment through SW upgrade in contrast with HW. In this paper, we propose a method to increase SW reliability in the mass production stage of Korean weapon systems.

By deriving the limitations of the test evaluation, it was intended to suggest a plan to improve the test evaluation system for the appropriateness of the number of ship crews according to the design and construction of troops-saving ships. Currently, the number of crew members by ship type is confirmed and specified in the ROC(Operation Requirement Performance) in the early stages of design, such as conceptual design, but there is a limit to testing and evaluating the appropriateness of ensuring reliability of combat performance.

There are many technical datum in related with design, test & evaluation and logistic support which will be exchanged between geographically isolated units and heterogeneous hardwares & softwares in developing and operating the weapon systems. The paper proposes the conceptual database schema to establish configuration management information systems in which these datum can be automatically interchanged, tracked, audited and status-accounted without errors under the various environments. The paper investigates how to identify and classify the data in accordance with document identification, task analysis, system development, logistic support, system test & evaluation and data management. Furthermore, the investigation includes drawing the subject areas and modeling the conceptual database schema to explain the relationships between these datum. Thus, the paper results in the conceptual framework and data models of configuration management information systems, while additional customization efforts be required in applying the models to a specific weapon systems R&D.

This paper examines the ongoing research on ways to improve cybersecurity during the entire life cycle of weapons systems applied in advanced countries such as the United States, analyzes restrictions on obtaining domestic weapons systems, and presents effective security evaluation measures. By consistently performing mission-based risk assessment in the cybersecurity test and evaluation plan suitable for domestic circumstances at all stages of acquisition, important information is provided to major decision-making organizations in a timely manner to support decision-making, and to respond to identified vulnerabilities in cybersecurity. It is proposed to set the rules of engagement so that the protection measures can be verified, and a simulated invasion is proposed. In addition, the proposed cybersecurity test and evaluation system was compared with the domestic weapon system test and evaluation. Through this, the mission-based risk assessment element was grafted into the cybersecurity test and evaluation system research conducted so far to identify risks in a timely manner between acquisition projects, thereby supplementing the capability to support major decision-making.

As NCW has appeared, the importance of interoperability in modern warfare has been also increased. Korean Defense has constructed and used the Systems Interoperability Test & Evaluation System based on LISI, in order to increase interoperability between Defense Information Systems. However, its evaluating targets are limited to only the information systems, so that it is difficult to apply it to weapon systems. This paper proposes an integrated interoperability assessment framework for korean embedded software of weapon systems based on reviewing the limitations of SITES and the other interoperability assessment models.

최근 현대 무기체계는 최첨단 기술로 인한 무기체계 개발 속도 증가와 획득환경의 다변화와 더불어 이에 대한 위험도 동시에 증가하고 있다. 이에 따라 미국방부는 무기체계의 수명주기를 고려하여 시험평가를 지속 적용토록 강조하고 있다. 따라서 기존의 무기체계 시험평가 프로세스에서 다루는 시스템 설계에 대한 단계별 안전 활동의 강화의 필요성 역시 강조되고 있다. 그 중에서도 무기체계 개발의 핵심 활동에 해당하는 체계개발 단계는 양산에 들어가기 전의 최종 활동으로서 제대로 수행되어야만 초기에 의도한 무기체계 개발의 목적을 달성할 수 있을 것이다. 본 논문에서는 시스템 안전성 요소를 고려한 시험평가 프로세스의 개선사항 도출과 모델링을 통해 무기체계 시스템인 무기체계를 대상으로 적용 및 조정 구축에 대한 내용을 기술하고 있다. 본 연구의 결과를 토대로 향후 시험평가 기간의 단축 및 비용 절감과 데이터의 관리 및 추적 기능을 개선함으로써 무기체계 개발 후의 안전사고 발생 가능성을 줄일 수 있을 것으로 기대된다.

The importance of interoperability in modem warfare has been increasing ever since. Korean Ministry of National Defense has constructed and used the Systems Interoperability Test & Evaluation System in order to evaluate level of interoperability among defense information systems. However, as primary targets of SITES were information systems, there is limitation to be applied to weapon systems. This paper proposes an interoperability testing architecture and interoperability testing configuration items which encompass various aspects of interoperability testing. We developed a prototype which proved that the proposal can be realized and useful.

The live fire test has been playing a critical role in evaluating the goals-to-meet of the weapon systems which utilize the power of explosives. As such, the successful development of the test systems therein is quite important. The test systems development covers that of ranges and facilities including system-level key components such as mission control, instrumentation or observation, safety control, electric power, launch pad, and so on. In addition, proper operational guidelines are needed with well-trained test and operation personnel. The emerging weapon systems to be deployed in future battle field would thus have to be more precise and dynamic, smarter, thereby requiring more elaboration. Furthermore, the safety consideration is becoming more serious due to the ever-increasing power of explosives. In such a situation, development of live fire test systems seems to be challenging. The objective of the paper is on how to incorporate the safety and other requirements in the development. To achieve the goal, an architectural approach is adopted by utilizing both the system components relationship and safety requirement when advanced instrumentation technology needs to be developed and deteriorated components of the range are replaced. As an evaluation method, it is studied how the level of maturity of the test systems development can be assessed particularly with the safety requirement considered. Based on the concepts of both systems engineering and SoS (System-of-Systems) engineering process, an enhanced model for the system readiness level is proposed by incorporating safety. The maturity model proposed would be helpful in assessing the maturity of safety-critical systems development whereas the costing model would provide a guide on how the reasonable test resource allocation plan can be made, which is based on the live fire test scenario of future complex weapon systems such as SoS.
