A Layered Software Architecture for the Management of a Manufacturing Company
In this paper we describe a layered software architecture in the management of a manufactur-ing company that intensively uses computer technology. Application tools, new and legacy, after the updating, operate in a context of an open web oriented architecture. The software architecture enables the integration and interoperability among all tools that support business processes. Manufacturing Executive System and Text Mining tools are excellent interfaces, the former both for internal production and management processes and the latter for external processes coming from the market. In this way, it is possible to implement, a computer integrated factory, flexible and agile, that immediately responds to customer requirements.ICT, Service Oriented Architecture, Web Services, Computer-Integrated Factory, Application Software
Industrial agents in the era of service-oriented architectures and cloudbased industrial infrastructures
The umbrella paradigm underpinning novel collaborative industrial systems is to consider the set of
intelligent system units as a conglomerate of distributed, autonomous, intelligent, proactive, fault-tolerant,
and reusable units, which operate as a set of cooperating entities (Colombo and Karnouskos,
2009). These entities are forming an evolvable infrastructure, entering and/or going out (plug-in/plugout)
in an asynchronous manner. Moreover, these entities, having each of them their own functionalities,
data, and associated information are now connected and able to interact. They are capable of
working in a proactive manner, initiating collaborative actions and dynamically interacting with each
other in order to achieve both local and global objectives.info:eu-repo/semantics/publishedVersio

Engineering of next generation cyber-physical automation system architectures
Cyber-Physical-Systems (CPS) enable flexible and reconfigurable realization
of automation system architectures, utilizing distributed control architectures
with non-hierarchical modules linked together through different communication
systems. Several control system architectures have been developed and validated in
the past years by research groups. However, there is still a lack of implementation
in industry. The intention of this work is to provide a summary of current alternative
control system architectures that could be applied in industrial automation domain
as well as a review of their commonalities. The aim is to point out the differences
between the traditional centralized and hierarchical architectures to discussed ones,
which rely on decentralized decision-making and control. Challenges and impacts
that industries and engineers face in the process of adopting decentralized control
architectures are discussed, analysing the obstacles for industrial acceptance and the
new necessary interdisciplinary engineering skills. Finally, an outlook of possible
mitigation and migration actions required to implement the decentralized control
architectures is addressed.The authors would like to thank the European Commission for the support,
and the partners of the EU Horizon 2020 project PERFoRM (2016b) for the fruitful discussions.

Industrial automation based on cyber-physical systems technologies: Prototype implementations and challenges
Cyber-Physical Systems (CPS) is an emergent approach that focuses on the integration of computational applications with physical devices, being designed as a network of interacting cyber and physical elements. CPS control and monitor real-world physical infrastructures and thus is starting having a high impact in industrial automation. As such design, implementation and operation of CPS and management of the resulting automation infrastructure is of key importance for the industry. In this work, an overview of key aspects of industrial CPS, their technologies and emerging directions, as well as challenges for their implementation is presented. Based on the hands-on experiences gathered from four European innovation projects over the last decade (i.e. SOCRADES, IMC-AESOP, GRACE and ARUM), a key challenges have been identified and a prioritization and timeline are pointed out with the aim to increase Technology Readiness Levels and lead to their usage in industrial automation environments.The authors would like to thank for their support the European Commission, and the partners of the EU FP6 SOCRADES (www.socrades.net), EU FP7 GRACE (www.grace-project.org), EU FP7 IMC-AESOP (www.imc-aesop.eu) and EU FP7 ARUM (www.arum-project.eu) projects, for their fruitful support and discussions.info:eu-repo/semantics/publishedVersio
Interoperability for Industrial Internet of Things Based on Service-oriented Architecture
The new Industry 4.0 envisions a future for agile and effective integration of the physical operational technologies (OT) and the cyber information technologies (IT) as well as autonomous cooperation among them. However, the wide variety and heterogeneity of industrial systems and field devices -especially on the factory floor - increase integration complexity. To address these challenges, new technologies and concepts such as the Industrial Internet of Things (IIoT), Service-oriented Architecture (SoA), Semantic Technologies, Machine Learning and Artificial Intelligence are being introduced to the industrial environment. In this paper, we focus on how industrial automation systems and field devices can be integrated into the IIoT framework and coordinated to adapt to dynamic operating environment. Specifically, this paper proposed an interoperability solution that makes use of SoA and Semantic Technologies to achieve supervised coordination of IIoT application systems. To illustrate the potential of this approach, the Service-oriented Architecture-based Arrowhead Framework is used as the fundamental framework for the implementation of the approach.acceptedVersio
Service-oriented architecture for device lifecycle support in industrial automation
Dissertação para obtenção do Grau de Doutor em
Engenharia Electrotécnica e de Computadores
Especialidade: RobĂłtica e Manufactura IntegradaThis thesis addresses the device lifecycle support thematic in the scope of service oriented industrial automation domain. This domain is known for its plethora of heterogeneous equipment encompassing distinct functions, form factors, network interfaces, or I/O specifications supported by dissimilar software and hardware platforms. There is then an evident and crescent need to take every device into account and improve the agility performance during setup, control, management, monitoring and diagnosis phases.
Service-oriented Architecture (SOA) paradigm is currently a widely endorsed approach
for both business and enterprise systems integration. SOA concepts and technology
are continuously spreading along the layers of the enterprise organization envisioning
a unified interoperability solution. SOA promotes discoverability, loose coupling,
abstraction, autonomy and composition of services relying on open web standards â features that can provide an important contribution to the industrial automation domain.
The present work seized industrial automation device level requirements, constraints and needs to determine how and where can SOA be employed to solve some of the existent difficulties. Supported by these outcomes, a reference architecture shaped by distributed, adaptive and composable modules is proposed. This architecture will assist and ease the role of systems integrators during reengineering-related interventions throughout system lifecycle. In a converging direction, the present work also proposes a serviceoriented
device model to support previous architecture vision and goals by including
embedded added-value in terms of service-oriented peer-to-peer discovery and identification, configuration, management, as well as agile customization of device resources.
In this context, the implementation and validation work proved not simply the feasibility and fitness of the proposed solution to two distinct test-benches but also its relevance to the expanding domain of SOA applications to support device lifecycle in the industrial automation domain
