We examine interoperability for integrated training simulation of a mechanized infantry battalion that uses a war game model of Korean army, Combat 21, and virtual simulators of K1 tanks. We discuss issues and problems for integrated simulation of the virtual and constructive models, including differences between the model scopes, model resolutions, engagement algorithms, and data consistency and training audiences of the war game model and virtual simulators. From these, we identify interoperability requirements. We propose ways of resolving the problems using a model converter.

In the initial step of BIM based architectural design process, workloads are increased and the decision making process becomes more complex than those of the conventional design process. Technologies regarding distribution, exchange, classification, verification of BIM data are fundamental elements of construct environment for information sharing based on BIM. Interoperability of BIM model data is another issue to integrate BIM model. To improve interoperability in BIM-based collaboration, a model for utilizing formal&unformal design informations is suggested. Futhermore, Prototyping the model and practical test is conducted for advancement of data exchange making design data richen.

Recently, there is a rising interest in smart grid operating system which manages various types of distributed generation, smart meters, and electric vehicles with power grid. Considering the features of smart grid environment, the interoperability should be one of the important factors to build smart grid environment successfully. To secure interoperability, smart grid operating system should conform to some standards in terms of the data representation and communication. CIM and OPC-UA are the international standards widely used in smart grid domain for enabling interoperability. They provide common information model and the unified architecture for communicating between each systems or applications. In this paper, we illustrate a smart grid operating system that we have developed to secure interoperability between not only applications but also numerous legacy systems(applications) by implementing CIM based information model and OPC-UA based communication interface services.

Smart grid is called it as a system of systems. There are diverse types of systems in smart grid environment. Therefore, one of key factors to achieve smart grid successfully is interoperability among diverse systems. To secure interoperability, smart grid operating system should be developed complied with standards in terms of the data representation and communication. Common Information Model (CIM) and OLE Process for Control - Unified Architecture (OPC-UA) are the representative international standards in smart grid domain. Each standard defines data representation and communication by providing common information model and the unified architecture. In this paper, we explain a smart grid platform that we have developed to comply with CIM and OPC-UA standards for secure interoperability among numerous legacy systems.

Critical to more widespread use of Internet telephony are the smooth interoperability with the existing telephone network and the improved quality of voice connections. Of these requirements, this interoperability comes through the use of Internet Telephony Gateway's which perform protocol translation between an IP network and the Public Switched Telephone Network. In this paper, we have focused on the necessity and possibility of interoperability, and furthermore derives the necessary requirements for interoperability between IP networks and PSTN. For this purpose, we have analyzed the signaling protocols for gateway system. Then, we have modelled the inter-working part using the Petri-Net model. Through reachability trees of the Petri-Net model, we have confirmed that interoperability is possible, and that characteristics of deadlock, liveness, and boundness are satisfied.

Cloud computing has proven its efficiency, especially after the increasing number of cloud services offered by a wide range of cloud providers, from different domains. Despite, these cloud services are mostly heterogeneous. Consequently, and due to the rising interest of cloud consumers to adhere to a multi-cloud environment instead of being locked-in to one cloud provider, the need for semantically interconnecting different cloud services from different cloud providers is a crucial and important task to ensure. In addition, considerable research efforts proposed interoperability solutions leading to different representation models of cloud services. In this work, we present our solution to overcome this limitation, precisely in the IAAS service model. This solution is a framework permitting the semantic interoperability of different IAAS resources in a multi-cloud environment, in order to assist cloud consumers to retrieve the cloud resource that meets specific requirements.

본 논문에서는 정보기술아키텍처 구축 프로세스인 TAProcess(Technical Architecture Process)와 모든 조직에서 참조할수 있도록 만든 기술참조모델인 HanTRM(Technical Reference Model)과 HanTRM을 기반한 상호운용성평가시스템을 설계하였다. TAProcess는 효율적인 정보기술의 도입, 관리 및 운영을 위한 표준 절차와 방법론을 제공하며 기술참조모델인 HanTRM은 기술참조모델을 만들려는 모든 조직에서 참조할 수 있도록 기본틀을 제공한다. 본 논문에서는 상호운용성평가시스템을 설계하기 위해 HanTRM을 활용하는 방안과 정보시스템간 상호운용성을 측정하는 절차를 제시하여 조직에 보다 유용하게 적용할 수 있도록 하였다.

현재의 무기체계는 다양한 표준과 프로토콜이 적용된 복합무기체계가 운용되어서 전장에서 연합 및 합동작전시 원활한 정보교환 실패의 위험이 있다. 무기체계간 신속한 상황판단으로 핵심표적에 대한 정밀타격을 수행하기 위한 무기체계들의 상호운용성은 전쟁수행의 핵심요소이다. 한국군은 전력화 이후 다수의 소프트웨어 및 하드웨어의 형상변경과 성능개선 소요가 발생하고 있으나, 상호운용성에 미치는 영향에 대한 검증제도가 없으며, 관련 시험 도구 및 시설도 전무한 실정이다. 또한 연합 및 합동훈련시 무기 / 전력지원체계의 세부 운용방식과 소프트웨어를 임의로 변경한 후 이에 따른 사용자 간 오류가 빈번히 발생하고 있다. 그래서 주기적인 무기체계간 상호운용성 검증이 필요하다. 이러한 문제를 해결하기 위하여 사람이 평가기간을 잡아서 1번 평가를 진행하는것이 아니라, AI가 24시간 무기 / 전력지원 체계간 상호운용성을 지속적으로 평가하여 전쟁수행능력을 고도화해야 한다, 이러한 문제점을 해결하기 위하여 자연어 처리기법(①Word2Vec 모델 ②FastText 모델 ③Swivel 모델)을 적용(공개된 알고리즘과 소스코드 사용)하여 국방상호운용성 능력향상을 위한 사전연구를 수행하였다. 이 실험의 결과를 바탕으로 사람에 의존하지 않고, 자동화된 국방상호운용성 평가도구를 구현하기 위한 방법론(자연어 처리 모델을 통한 상호운용성 소요평가 / 수준측정의 자동화된 평가)을 향후 제시하고자 한다.

Lately CBD methodologies like as CBD96, Catalysis, Fusion, and SCIPIO have been introduced. These methodologies has their own proprietary component reference model. Using proprietary reference model falls interoperability among methodologies. Furthermore it can cause confusion and difficulty for component developers, In this paper, we propose a integrated component meta-model for support consistency and interoperability among component designs. Also, we compare our proposed meta model to existing component reference model by using component's characteristics. We expect that it is easy to add new meta model elements and extends meta-model by using integrated component meta-model.

As Geographic Information Systems represents three-dimensional topological Information, the systems provide accurate and delicate services for user. In order to execute three-dimensional topological operations, a dimensional transformation and heterogeneous spatial models should be used. However, the existing systems that use the dimensional transformation and the heterogeneous models, are not only difficult to operate the spatial operators, but also happened to support non- interoperability. Therefore, in order to support the spatial operation as well as interoperability between dimensions, we propose three-dimensional spatial operators for the proposed models. We defined the three-dimensional spatial operators prior to designing the proposed model. We also implemented the operators of proposed model and evaluated the implemented model on the component environment. Finally, the proposed model is able to not only support interoperability among systems but also execute spatial queries efficiently on three-dimensional spatial objects.
