There are many demands for interoperability between weapon systems as the operational needs for joint and coalition based on network in modern and future warfare have been increasingly needed. In DoD, LISI has been applied throughout information system life cycle from the planning phase to the development phase to assess the level of interoperability. We also developed SITES which is a tool to assess the level of interoperability in information systems. But we should extend the assessment model from the previous information systems to the weapon systems to assess the level of interoperability including weapon systems as well as information systems. In this paper, we proposed the assessment model of interoperability, implemented the E-SITE based on the proposed model, applied 12 weapon systems and analyzed the experimental result.

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.

본 논문은 현재 국방 체계의 상호운용성 수준을 평가하는 방법으로 사용하는 LISI 모델에 대해 개선되어야 할 내용을 제시한다. 우리 군은 국방 체계에 대해 상호운용성 수준 측정을 위해 LISI를 기반으로 한 자동화 도구를 활용하는 등 상호운용성 확보를 위해 많은 노력을 기울이고 있다. 그러나 소요제기/개념단계, 설계 단계에서 적용되는 LISI 모델에는 미흡한 점이 있다. 이를 극복하기 위해 본 논문에서는 아키텍처 구축 시 LISI를 적용하는 방법에 대해 제안한다. 상호운용성이 확보 가능한 아키텍처를 구축하기 위해 서는 LISI를 기반으로 아키텍처 대안들을 평가함으로써 향후 개발에 적용될 아키텍처가 상호운용성 요구를 달성하고 있음을 검증해야 한다. 더불어 본 논문은 LISI 모델 기반 상호운용성 평가를 위해 주요하게 고려되는 능력모델에 대한 절차(P), 응용(A), 기반구조(I), 데이터(D) 내용을 참조모델을 통해 최신화하는 방안에 대해 제안한다.

국방 정보분야의 효율 효과적인 개발 및 운용을 위해 통합과 표준의 설정 등을 통한 상호운용성 확보가 요구된다. 상호운용성 표준화 기술은 전사적 아키텍처 기반 상호운용성 조정 통제, 플랫폼 중심의 상호운용성 확보를 위한 공통운용환경 및 데이터공유환경 구축에서 시작하여, 현재에는 네트워크 중심 환경에 적합한 SOA(Service Oriented Architecture) 기반 상호운용성 증진 전략으로 패러다임이 변화하고 있다. 미군의 경우 단일체계 관점에서 복합체계 관점으로 확대 적용을 위하여 기존의 공통운용환경 및 데이터 공유환경을 SOA 기반의 NCES(Net-Centric Enterprise Service)로 전환을 추진해왔다. 또한 이와 병행하여 미 육군 수준에서는 전쟁을 수행하는 각 객체를 컴퓨팅 환경으로 구분하여 육군 차원의 공통운용환경을 구축하고 있다. 이에 본 고에서는 국방 공통운용환경의 동향을 미군의 사례를 중심으로 살펴보고 시사점을 도출한다.

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.

Recently, Levels of Information Systems Interoperability (LISI) that are used for assessing the information systems interoperability are defined according to the importance of interoperability among information systems. At that time, it is necessary to the construction of an assessment information repository to store and retrieve the interoperability assessment data efficiently. An LISI repository constructed for storing and retrieving an assessment information should support assessment systems that are developed in various Platforms and provide its functions by a standardized way. Business logics of LISI repository should be developed as distributed components, and we need to modify existing software design methods to show characteristics of LISI repository in addition to the standardized LISI data expression. Also a concrete method to recognize various implementation technologies and to apply them to implementation of LISI repository is needed. This paper provides a design method for developing an LISI repository that is considering the characteristics of LISI repository by three concerns, and an implementation scheme that can apply to the integration of the various repository implementation technologies systematically, as the LISI repository development framework for constructing the LISI repository. These help developers to construct the LISI repository effectively by providing concrete guidelines for considerations and appliable methods to construct the LISI repository.

The current weapon system is operated as a complex weapon system with various standards and protocols applied, so there is a risk of failure in smooth information exchange during combined and joint operations on the battlefield. The interoperability of weapon systems to carry out precise strikes on key targets through rapid situational judgment between weapon systems is a key element in the conduct of war. Since the Korean military went into service, there has been a need to change the configuration and improve performance of a large number of software and hardware, but there is no verification system for the impact on interoperability, and there are no related test tools and facilities. In addition, during combined and joint training, errors frequently occur during use after arbitrarily changing the detailed operation method and software of the weapon/power support system. Therefore, periodic verification of interoperability between weapon systems is necessary. To solve this problem, rather than having people schedule an evaluation period and conduct the evaluation once, AI should continuously evaluate the interoperability between weapons and power support systems 24 hours a day to advance warfighting capabilities. To solve these problems, To this end, preliminary research was conducted to improve defense interoperability capabilities by applying natural language processing techniques (①Word2Vec model, ②FastText model, ③Swivel model) (using published algorithms and source code). Based on the results of this experiment, we would like to present a methodology (automated evaluation of interoperability requirements evaluation / level measurement through natural language processing model) to implement an automated defense interoperability evaluation tool without relying on humans.

For effective battlefield situation awareness and command resolution, information exchange without seams between systems is essential. However, since each system was developed independently for its own purposes, it is necessary to ensure interoperability between systems in order to effectively exchange information. In the case of our military, semantic interoperability is guaranteed by utilizing the common message format for data exchange. However, simply standardizing the data exchange format cannot sufficiently guarantee interoperability between systems. Currently, the U.S. and NATO are developing and utilizing information exchange models to achieve semantic interoperability further than guaranteeing a data exchange format. The information exchange models are the common vocabulary or reference model,which are used to ensure the exchange of information between systems at the content-meaning level. The information exchange models developed and utilized in the United States initially focused on exchanging information directly related to the battlefield situation, but it has developed into the universal form that can be used by whole government departments and related organizations. On the other hand, NATO focused on strictly expressing the concepts necessary to carry out joint military operations among the countries, and the scope of the models was also limited to the concepts related to command and control. In this paper, the background, purpose, and characteristics of the information exchange models developed and used in the United States and NATO were identified, and comparative analysis was performed. Through this, we intend to present implications when developing a Korean information exchange model in the future.
