- Application system and services: design and implementation - a cook bookPublication . Delsing, Jerker; Albano, Michele; Ferreira, Luís Lino; Blomstedt, Frederik; Olovsson, Per; Varga, PalIn previous chapters local automation clouds and a SOA based architecture supporting the design and implementation of IoT based automation systems. This chapter is devoted to design and implement of application services. The ambition is to discuss: • Design of an Arrowhead Framework system • Implementation of such system and its services • Interoperability test
- Arrowhead Framework core systems and servicesPublication . Delsing, Jerker; Eliasson, Jens; Albano, Michele; Varga, Pal; Ferreira, Luís Lino; Derhamy, Hasan; Hegedus, Csaba; Puñal Pereira, Pablo; Carlsson, OscarIn chapter 2 local clouds was discussed followed by a local cloud automation architecture in chapter 3. The automation architecture supports the implementation of local automation clouds. Such implementation is supported by the Arrowhead Framework and its core Systems and Services. The Arrowhead Framework core systems enables the creation and operation of local clouds. First implementation of these systems and their services are described in detail in this chapter. There currently are two types of core services within the Arrowhead Framework: - Mandatory core systems - needed to establish the minimal local cloud - Automation support core systems – extending local cloud capabilities intending to provide support for the design and operation of local automation clouds an interaction between local clouds.
- Attack Detection in Cyber-Physical Production Systems using the Deterministic Dendritic Cell AlgorithmPublication . Pinto, Rui; Gonçalves, Gil; Tovar, Eduardo; Delsing, JerkerCyber-Physical Production Systems (CPPS) are key enablers for industrial and economic growth. The introduction of the Internet of Things (IoT) in industrial processes represents a new revolution towards the Smart Manufacturing oncept and is usually designated as the 4 th Industrial Revolution. Despite the huge interest from the industry to innovate their production systems, in order to increase revenues at lower costs, the IoT concept is still immature and fuzzy, which increases security related risks in industrial systems. Facing this paradigm and, since CPPS have reached a level of complexity, where the human intervention for operation and control is becoming increasingly difficult, Smart Factories require autonomic methodologies for security management and self-healing. This paper presents an Intrusion Detection System (IDS) approach for CPPS, based on the deterministic Dendritic Cell Algorithm (dDCA). To evaluate the dDCA effectiveness, a testing dataset was generated, by implementing and injecting various attacks on a OPC UA based CPPS testbed. The results show that these attacks can be successfully detected using the dDCA.
- Making system of systems interoperable – The core components of the arrowhead frameworkPublication . Varga, Pal; Blomstedt, Fredrik; Lino Ferreira, Luis; Eliasson, Jens; Johansson, Mats; Delsing, Jerker; Martínez de Soria, IkerThe objective of the Arrowhead Framework is to efficiently support the development, deployment and operation of interconnected, cooperative systems. It is based on the Service Oriented Architecture philosophy. The building elements of the framework are systems that provide and consume services, and cooperate as systems of systems. Some commonly used systems, such as orchestration, authorization or service registry are considered as core. These can be used by any system of systems that follow the guidelines of the Arrowhead Framework. Within the framework, systems – using different information exchange technologies during collaboration – are helped through various approaches. These include the so-called Interoperability Layer, as well as systems and services for translation. Furthermore, one of the main problems of developing such highly interoperable systems is the lack of understanding between various development groups. Adequate development and service documentation methodologies can help to overcome this issue. The design, development and verification methodology for each service, system and system of systems within the Arrowhead Framework supports that these can be implemented, verified, deployed, and run in an interoperable way. This paper presents an overview of the framework together with its core elements – and provides guidelines for the design and deployment of interoperable, Arrowhead-compliant cooperative systems.
- QoS-as-a-Service in the Local CloudPublication . Lino Ferreira, Luis; Albano, Michele; Delsing, JerkerThis paper presents an architecture that supports Quality of Service (QoS) in an Arrowhead-compliant System of Systems (SoS). The Arrowhead Framework support local cloud functionalities for automation applications, provided by means of a Service Oriented Architecture (SOA), by offering a number of services that ease application development. On such applications the QoS guarantees are required for service fruition, and are themselves requested as services from the framework. To fulfil this objective we start by describing the Arrowhead architecture and the components needed to dynamically in run-time negotiate a system configuration that guarantees the QoS requirements between application services.
- Quality of Service on the Arrowhead FrameworkPublication . Albano, Michele; Barbosa, Paulo; Silva, José; Duarte, Roberto; Lino Ferreira, Luis; Delsing, JerkerQuality of Service (QoS) is an important enabler for communication in industrial environments. The Arrowhead Framework was created to support local cloud functionalities for automation applications by means of a Service Oriented Architecture. To this aim, the framework offers a number of services that ease application development, among them the QoSSetup and the Monitor services, the first used to verify and configure QoS in the local cloud, and the second for online monitoring of QoS. This paper describes how the QoSSetup and Monitor services are provided in a Arrowhead-compliant System of Systems, detailing both the principles and algorithms employed, and how the services are implemented. Experimental results are provided, from a demonstrator built over a real-time Ethernet network.
- The Arrowhead Framework architecturePublication . Delsing, Jerker; Varga, Pal; Ferreira, Luís Lino; Albano, Michele; Puñal Pereira, Pablo; Eliasson, Jens; Carlsson, Oscar; Derhamy, HasanThe objective of Arrowhead Framework architecture is to facilitate the creation of local automation clouds. Thus enabling local real time performance and security. Paired with simple and cheap engineering. While simultaneously enabling scalability through multi cloud interaction. The architecture addresses the move from large monolithic organisations towards multi-stakeholder cooperations where cooperation are fostered by market requirements. This is to support the high level topics in today’s society such as sustainability, flexibility, efficiency and competitiveness in production.
