Service-oriented design of environmental information systems

Service-orientation has an increasing impact upon the design process and the architecture of environmental information systems. This thesis specifies the SERVUS design methodology for geospatial applications based upon standards of the Open Geospatial Consortium. SERVUS guides the system architect to rephrase use case requirements as a network of semantically-annotated requested resources and to iteratively match them with offered resources that mirror the capabilities of existing services

SoaML-basierter Entwurf eines dienstorientierten Überwachungssystems. [Workshop]

Von einem Überwachungssystem zur Begleitung von Personen innerhalb von Gebäuden wird häufig gefordert, sich in die bestehende Anwendungslandschaft eines Unternehmens integrieren zu lassen und vorhandene Anwendungsfunktionalität möglichst wiederzuverwenden. Anwendungslandschaften werden verstärkt in Form dienstorientierter Architekturen strukturiert, weshalb ein integrierbares Überwachungssystem ebenfalls dienstorientiert entworfen werden sollte. Mit der Service oriented architecture Modeling Language (SoaML) existiert ein Standard, der eine Modellierung eines dienstorientierten Überwachungssystems ermöglicht. In dieser Arbeit werden die hierfür notwendigen Elemente der SoaML identifiziert und in einen Entwicklungsprozess eingeordnet

Agile Service Engineering in the Industrial Internet of Things

The emerging Industrial Internet of Things (IIoT) will not only leverage new and potentially disruptive business models but will also change the way software applications will be analyzed and designed. Agility is a need in a systematic service engineering as well as a co-design of requirements and architectural artefacts. Functional and non-functional requirements of IT users (in smart manufacturing mostly from the disciplines of mechanical engineering and electrical engineering) need to be mapped to the capabilities and interaction patterns of emerging IIoT service platforms, not to forget the corresponding information models. The capabilities of such platforms are usually described, structured, and formalized by software architects and software engineers. However, their technical descriptions are far away from the thinking and the thematic terms of end-users. This complicates the transition from requirements analysis to system design, and hence the re-use of existing and the design of future platform capabilities. Current software engineering methodologies do not systematically cover these interlinked and two-sided aspects. The article describes in a comprehensive manner how to close this gap with the help of a service-oriented analysis and design methodology entitled SERVUS (also mentioned in ISO 19119 Annex D) and a corresponding Web-based Platform Engineering Information System (PEIS)

Services in Industrie 4.0 - Interaction-based Architecture as defined in the DIN SPEC 16593-1

A common approach to face the requirements of smart factories is the definition of a reference model that provides guidance to software and system engineers when defining system (of systems) architectures. The paper provides an overview about the DIN SPEC 16593-1 recently published as a refinement of the Reference Architecture Model Industrie 4.0 (RAMI4.0). It is part 1 of an intended series of DIN SPEC 16593-x finally leading to a Reference Model of Industrie 4.0 Service Architecture (RM-SA). It clarifies the use of the terms "service" and service-oriented architecture (SOA) in RAMI4.0. The paper describes the classification into service types and the two major underlying interaction types: procedure-based interactions and state machine-based interactions to be used in Industrie 4.0

Soziale Angst bei schwerstadipösen Patienten

This paper provides an overview about the conceptual work performed by the VDI/VDE GMA working group 7.21 towards the specification of a reference model for Industrie 4.0 service architectures. It focuses on the conceptual design of service-oriented architecture (SOA) relying upon the “I40 component” as a core basic concept across the whole value network. Furthermore, the paper discusses the relevance of reference models of the Internet of Things and Services as a foundation

Smart Factory Web. Plattform eines offenen Marktplatzes für Produktionsfähigkeiten

The paper describes the goals and architecture of the Smart Factory Web as a platform for the networking of factories. The capabilities and capacities of factories are adapted and combined to achieve a flexible order fulfilment. This enables the Industrie 4.0 application scenarios “order controlled production” and “adaptable factory”. The architectural concepts of IIC and Industrie 4.0 as well as the international standards OPC UA and AutomationML form the basis for a sustainable and open solution
