Abstract: In this paper, we propose an indicator to systems-of-systems (SoS) structural analysis through dependencies evaluation which is based on interoperability and exchange inefficiency assessments, with dependencies representing links between component systems within the SoS. Interoperability is a quality that can be viewed from various perspectives. Therefore, we propose an illustrative classification for interoperability that embraces: barriers, scopes and levels. Our study involves a set of metrics to assess each interdependency’s interoperability barriers within the SoS through interoperability levels. Two different case studies, from the Moroccan economic infrastructure, are presented to apply the proposed approach. Results are cross-compared and evaluated.

Abstract: The system architecture for self-organizing smart home ecosystems must fulfill the standard requirements of measuring home conditions, processing instrumented data, and monitoring home appliances as well as providing self-configurations mechanisms for the sensors and actors forming the ecosystem. The communication framework should allow devices to discover counterpart devices, discover the services they offers, invoke these services when needed and get notifications about the state changes of their cooperation partners. Our approach takes advantages of the communication framework OPC UA, since it provided a set of prebuild services, which can be adapted to our needs. The following lines describe the OPC UA communication framework first and describe the architecture of our communication model secondly.

Abstract: IEC61850 uses the abstract communication service interface (ACSI) and specific communication service mapping (SCSM) definition method. Most of data structure and communication service are mapping to Manufacturing Message Specification (MMS), but MMS has high abstraction, many 61850 ACSI services are mapping to one mms service [6]. At the same time there are many fuzzy definitions even mapping deviation phenomena, different vendors may have inconsistent understanding to the standard, this is harmful to the interoperability. This paper provide analysis and comparison to the 61850 ACSI services mapping to the MMS read, including GetDataValues, GetDataSetValues, GetBRCBValues and so on, and based on these, firstly gives implementation using the mms-ease lite of SISCO Company and detailed explanations of actual telegram. Our research is helpful to eliminate understanding difference and achieve interoperability. System test uses multiple popular software of different company to simulate as server, and the widely used network protocol analyzer software Omicron IEDScout is used to capture packets, the result verifies our implementation satisfy the functionality and interoperability.

Abstract: The exchange of data between systems is a very complex process. This is the resultant of a huge variety of communication tools, the differences in the systems' structure, data storage, etc. Therefore, integration of systems - highly desired by businesses - becomes equally important challenge as the possession of the systems. Systems integration, however, is responsible only for the exchange of information. Wider notion from integration is interoperability. Treated as a systems property, allows not only to exchange information but also mutual understanding between them. The paper presents the concept of middleware application that could provide the interoperability of enterprise systems. The application structure was based on three aspects: the transformation, completeness verification and validation of data that can be exchanged between ERP and MES systems. Each of these aspects is discussed in this paper. The application uses a unified model of data based on a dedicated language B2MML.

Abstract: This research is to show that functions are the indispensable elements for e-marketplace construction, and that basic functions in particular are able to meet the demand for highly interoperable and cost-effective e-marketplaces. Specifically, this research relies heavily on historical literature event methodology by studying existing electronic marketplaces through thousands of research papers, ranging among 1,221 articles published in journals and conferences over the period of 1986-2012. Based on the basic functions generated from the function published year and the function counted quantity, this research eventually shows that e-marketplace designers, facilitators, buyers, and sellers will be able to construct and select a suitable e-marketplace automatically for their diverse purposes.

Abstract: The disunion of communication protocol standards at present creates a huge barrier against the interconnection and interoperability of heterogeneous devices in home. To solve this problem, a method of multiple protocols conversion of home gateway was proposed to integrate a variety of heterogeneous protocol networks. Firstly, a new task description language based on ClassAD was designed to describe different heterogeneous devices for communicating each other in home networks. And a plug-in expansion mechanism was introduced to improve the scalability of heterogeneous protocols and the throughput of home networks system. As a result, the ability of semantic interoperability of heterogeneous devices is achieved to integrate new applications and drivers into the deployed intelligent home system during runtime based on the proposed home gateway.

Abstract: Global Navigation Satellite System (GNSS) interoperability could make use of the information from different navigation satellite systems. To estimate GNSS interoperability at the system level, an innovative assessment algorithm was presented in this paper. First of all, three assessment parameters, namely, Dilution Of Precision (DOP), Navigation Satellite System Precision (NSSP) and Navigation Satellite System Integrity (NSSI) were introduced. Secondly, availability and continuity of the assessment parameters were adopted to quantify the GNSS performance. A further step was then taken to focus on the assessment rule for GNSS performance by employing the weighted sum of availability and continuity. Simulation results demonstrate that GNSS performance could be improved significantly by interoperability.

Abstract: Power Grid in China integration running trend makes EMS(Energy Management System) at all levels of information exchange between the increasingly urgent demand. And CIM is the most important base information. In order to solve the model information differences between different EMS, this paper analyzes the current EMS model information related to the standardization of applications, from standard CIM model, the model file formats and file content model three aspects, based on interoperable standards IEC61970 process-oriented information model calibration and validation process for each part of the key technologies are discussed in detail. Through the practical application of the method validation results show that the calibration method is reasonable and correct.

Abstract: For the purpose of measuring document interoperability, a Feature Data Model (FDM) of open office document format is proposed to deal with documents. Feature Data is defined as a document container, which contains a number of document features. Each data object in the container meets different document standards and specifications. By using FDM, the instance documents establish the mapping relationships of features between different formats. Then use Feature Data as assistance to measure interoperability and calculate the statistical results automatically. The Documents Interoperability Measuring System (DIMS) mentioned in this paper is implemented by JAVA to prove the feasibility of this model and architecture.

Abstract: The Military Scenario Definition Language (MSDL) is an approved SISO standard for describing components of military scenarios that can be shared across a variety of modeling and simulation systems. However, the “last mile problem” for MSDL development is to have a user interface that represents information flowing to/from C2 and simulation systems. We have developed an open-source Toolset for this purpose: MSDL Scenario Editing Toolset (MSDLSET), providing an easy-to-use graphical user interface to MSDL developers that can serve as a surrogate input/output GUI or alternately to generating MSDL file. MSDLSET is developed using other open-source Tools: Xcentric's JaxFront and BBN's OpenMap. MSDLSET provides easy and efficient means for the end user to edit validate and add MSDL components to the MSDL file. Numerous initiatives are in progress to employ the new Toolset and to realize the benefits of exchanging scenarios files across diverse systems.
