Engineering methods and tools for cyber–physical automation systems
Much has been published about potential benefits of the adoption of cyber–physical systems (CPSs) in manufacturing industry. However, less has been said about how such automation systems might be effectively configured and supported through their lifecycles and how application modeling, visualization, and reuse of such systems might be best achieved. It is vitally important to be able to incorporate support for engineering best practice while at the same time exploiting the potential that CPS has to offer in an automation systems setting. This paper considers the industrial context for the engineering of CPS. It reviews engineering approaches that have been proposed or adopted to date including Industry 4.0 and provides examples of engineering methods and tools that are currently available. The paper then focuses on the CPS engineering toolset being developed by the Automation Systems Group (ASG) in the Warwick Manufacturing Group (WMG), University of Warwick, Coventry, U.K. and explains via an industrial case study how such a component-based engineering toolset can support an integrated approach to the virtual and physical engineering of automation systems through their lifecycle via a method that enables multiple vendors' equipment to be effectively integrated and provides support for the specification, validation, and use of such systems across the supply chain, e.g., between end users and system integrators

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.
