In Korean military measuring systems interoperability is based on LISI (Level of Information System Interoperability) model at the requirement generation and acquisition process. However, LISI model cannot be used for interoperability measurement of system of systems (SoS) because LISI model is focused on interoperability measurement of a given system or system pair. Also, LISI model cannot provide quantitative information for interoperability decision because of qualitative rather than quantitative approach. This paper proposes a quantitative interoperability measurement methodology of SoS. At the proposed methodology, mission threads and supporting systems are identified using architecture approach, and Interoperability of SoS is measured with systems multiplicity and resemblance coefficient. Finally, a case study is presented to show the usefulness of the methodology.

지휘 통제 자동화 체계는 군의 현대화를 위해서는 반드시 필요한 체계이며, 다양한 기능들이 복합된 매우 복잡한 체계이다 체계의 완전한 성능을 발휘하기 위해서는 다른 많은 체계들과 복합 연동 운용되어야 하는 특성이 있다. 이 모든 체계들은 기술 집약적 고가의 체계들이기 때문에 이 체계들을 동시에 개발, 구축하기는 곤란하므로 체계의 효용성, 경제성등을 분석하여 국가적 차원에서의 철저한 우선순위를 결정하여 구축해나가야 할 것이다

This study presents the direction of the Republic of Korea Army in the future by examining the Manned and Unmanned Teaming(MUMT) Systems of the Military Advanced Countries of the United States, Israel, and France. In this study, the current status of the U.S. Ground Forces' 'Squad-X' program, the Israeli Ground Forces' Digital Army Program (DAP), and the French Army's Scorpion program were examined. Next, it was followed by a discussion of The Combat concept, a way of fighting in the future battlefield, with the development trend of a complex Combat system with various weapon systems supporting it. Finally, based on this, the direction of the development of MUMT system, which the Republic of Korea Army should engage in in the future, was presented as a conclusion. Since such MUMT system of advanced military forces are being developed in a secret manner, continuous longitudinal research needs be conducted.

As the substantial increase in battlefield density, multiple and complex weapon systems, Ensuring the Survivability of the platform has been emphasized. Most of platforms have equipped with ASE (Aircraft Survivability Equipment) system in order to protect the platform and operator against at modernized hostile weapon. ASE system enhance the survivability of the platform through providing accurate situation awareness information by detecting and countermeasuring hostile threats. One of Key factor of the AE system performance is handling multiple and complex threats. In this study, it describes the fact that the performance of ASE system with proposed threat integration algorithm is verified in the developed threat emulation system and also, suggests system verification method before deployment by dealing with complex threat situation.

As the substantial increase in battlefield density, multiple and complex weapon system, Ensuring the Survivability of the platform has been emphasized. Most of platforms have equipped with ASE (Aircraft Survivability Equipment) system in order to take action against at modernized hostile weapon under current battlefield. ASE system enhance the survivability of the platform through providing accurate situation awareness information by detecting and countermeasuring hostile threats. One of Key factor of the AE system performance is handling multiple and complex threats. Multiple and complex threat emulation is an effective means of ASE system verification In this study, It discuss system verification method before installation by dealing with complex threat situation consists of individual threat.

In this study, assuming that the maritime manned-unmanned systems, which will be used as the main force of the ROK Navy in the future, conducts its sea line of communication(SLOC) protection operations, the combat effectiveness against major threats was measured, and through this, the development direction of the manned-unmanned systems was suggested. Multi-criteria decision-making techniques such as Delphi and AHP were used to measure combat effectiveness, and the AHP survey was conducted on 40 naval officers, including 25 senior officers who are well-understood in the combat effectiveness of the weapons system and MUM-T. As an evaluation index for measuring combat effectiveness, the OODA loop was set as the main attribute, followed by Observe(0.358), Orient(0.315), Act(0.217), and Decide(0.110). The combat effectiveness of each major threat in SLOC, the lowest alternative, was measured to be 1.68 times higher than the response to maritime conflicts in neighboring countries and 3.61 times higher than the response to transnational threats. These results are expected to support rational decision-making in determining the level of technology required for acquisition of marine manned-unmanned systems and establishing operational plans for naval forces.

해군에서 운용하는 각 함정은 여러 가지 무기체계를 동시에 탑재하고 있는, 고가의 복합무기체계이다. 주어진 기간동안 효과적인 정비를 수행함으로써, 가동률을 극대화하는 것이말로 복합무기체계인 함정을 효과적으로 운용하는 방법이며, 경제적인 국방운용이라 부를 수 있을 것이다. 정비인시는 여러 무기체계가 동시에 탑재된 복합무기체계 정비의 핵심이다. 정비인시를 정확하게 알고 있어야만, 제한된 정비기간을 각 무기체계에 정확히 할당할 수 있을 것이며, 최적의 요소에 대한 정비가 수행될 수 있을 것이다. 본 연구에서는 해군에서 운용중인 특정장비에 대한 약 10년간의 정비자료를 이용하여 정비인시를 예측하는 모델을 제안하였다. 모델의 성능은 R2 Score를 통해 0.69의 준수한 수치를 보였다. 이 모델을 통해 조금더 세밀하고, 정확한 정비인시 예측과 정비계획 수립이 가능하리라 판단하였다.

Increasing of the multinational corporation brought into the international multimodal Increasing of the multinational corporation brought into the international multimodal transport on the logistics environment. In case of Europe which have a great infrastructure, they are tried to develope a second of the silk road constantly. This paper emphasized the importance of international multimodal transport and proposed the model for northeast multimodal transport. For this research, we analyzed the multimodal transport system in Europe and north corridor of TAR. We are expecting economic effect of the route is including republic of korea and developed a model for connecting with sea, air and road. Actually, this research can not be enough data of numerical value for proving this effectiveness. but we developed and proposed a specific route of multimodal transport that was never suggested. Consequently, we established basic ground for comparing each transport route in the future research.

After patrol corvett Cheonan was hit and sank on duty, the Republic of Korea Navy has tried to install hybrid propulsion system on naval ship to reduce vibration and noise problems during navigation. The hybrid propulsion system has advantage that propulsion motor can be propelled in low speed operation of the vessel. This can be a better quietness than a mechanical propulsion system which consists of a conventional internal combustion engines. And more economical operation is possible by using a propulsion motor in a low speed operation where a fuel efficiency of the internal combustion engine is poor. In this paper, we set up virtual ship on the basis of a combat support ship in the Republic of Korea Navy, economically compared and analyzed fuel consumption between conventional and hybrid propulsion system. As a result, it was confirmed that the fuel efficiency of hybrid propulsion system which use electric motor had been relatively improved.
