SOHOMA 2016: A description and analysis method for reconfigurable production systems
New production systems are highly reconfigurable and interact with dy-namic industrial environments. Their modelling, simulation and analysis of the opera-tions and evaluation of performances are now much more complex than in the past when system had a static and predefined behavior. This paper proposes a formalism to describe complex production systems, based on utilization of FSA (Finite Status Au-tomaton). This approach is enabling better understanding and sharing with stakeholders of how a system works, but it is also a good basis for computer based simulation and control. The interaction with external environments is structured in terms of External Events (inputs) and Trigger Outputs. The analysis of the system status evolution pro-vides the possibility to calculate KPIs in specific conditions or their evolution along the time. In the paper it is proposed a simplified description language to describe the au-tomaton including output generation and triggering of other functions of the production environment. The approach is implemented and demonstrated in a particular industrial domain: industrial machinery fabrication sector.

SOHOMA 2016: Instantiating the PERFoRM System Architecture for Industrial Case Studies
The PERFoRM project, an innovation action promoted under the scopeof the EU Horizon 2020 program, advocates the use of an Industrie 4.0 compliant system architecture for the seamless reconfiguration of robots and machinery. The system architecture re-uses the innovative results from previous successful R&D projects on distributed control systems domain, such as SOCRADES, IMCAESOP, GRACE and IDEAS. This paper, after describing the main pillars of the PERFoRM system architecture, focuses in mapping the system architecture into four industrial use cases aiming to validate the system architecture design before its deployment in the real environments.

IECON 2016: Towards Industrial Exploitation of Innovative and Harmonized Production Systems
Industrial competitiveness today means shorter product lifecycles, increased product variety and shorter time-tomarket. To face this challenge, the manufacturing industry is forced by different initiatives, namely Internet of Things, Industrie 4.0 and Cyber-Physical System to move from traditional control approaches towards intelligent manufacturing control systems that are dynamically adaptable to changing production environment and flexible to different processing tasks. For years several emergent intelligent approaches such as Multi-Agent Systems, Service-oriented Architecture, Plug-and- Produce systems and Cloud technologies have been developed in a variety of research fields. This paper reviews the state-of-theart methodologies and technologies of flexible and reconfigurable manufacturing systems outlining the differences between them and arising benefits within the vision of the PERFoRM (Production harmonizEd Reconfiguration of Flexible Robots and Machinery) project. Current trends and challenges in industrial implementation of these methodologies are reported and research opportunities are described.

IECON 2016: Assessment of industrial middleware technologies for the PERFoRM project
To meet the increasing requirements which are set for modern production systems regarding flexibility, reconfigurability and collaborative behavior, a common information, Communication & Control (ICT) platform for guaranteeing connectivity has to be put in place. Industrial Middleware, i.e. SW/HW solutions, which help connecting and mediating different industrial cyber-physical components of a distributed system (such as a production system) are an essential component of such a platform.The paper describes the assessment of existing industrial Middleware solutions which are targeting re-configurability and connectivity of modern industrial environments. It states a set of important functional requirements which need to be considered to select the right solution for individual use cases. A big emphasis is put into finding industrially applicable solutions.

IECON 2016: Specification of the PERFoRM Architecture for the Seamless Production System Reconfiguration
The world is assisting to the fourth industrial revolution, with several domains of science and technology being strongly developed and, specially, being integrated with each other, allowing to build evolvable complex systems. Data digitization, big-data analysis, distributed control, Industrial Internet of Things, Cyber-Physical Systems and self-organization, amongst others, are playing an important role in this journey. This paper considers the best practices from previous successful European projects addressing distributed control systems to develop an innovative architecture that can be industrially deployed. For this purpose, a particular design process has to be addressed in order to consider the requirements and functionalities from various use cases. To investigate the known practices, four use cases are enlighted in this paper, which cover a wide spectrum of the European industrial force, as well as industrial standards to support a smooth migration from traditional systems to the emergent distributed systems.

IECON 2016: Selection of a Data Exchange Format for Industry 4.0 Manufacturing Systems
With the emergence of the Industry 4.0 concept, or the fourth industrial revolution, the industry is bearing witness to the appearance of more and more complex systems, often requiring the integration of various new heterogeneous, modular and intelligent elements with pre-existing legacy devices. This challenge of interoperability is one of the main concerns taken into account when designing such systems-of-systems, commonly requiring the use of standard interfaces to ensure this seamless integration. To aid in tackling this challenge, a common format for data exchange should be adopted. Thus, a study to select the foundations for the development of such a format is hereby presented, taking into account the specific needs of four different use cases representing varied key European industry sectors.

IECON 2016: Functional Requirements for Reconfigurable and Flexible Cyber-Physical System
A truly global market characterized by aggressive competition on a global scale and rapid changes in process technology requires creating production systems that are easy to upgrade, being able to readily integrate new technologies and new functions. In these terms, PERFoRM (Production harmonizEd Reconfiguration of Flexible Robots and Machinery) a European funded project, aims at developing an innovative manufacturing system based on a new agile concept introducing the implementation of methods and methodologies for transforming existing production systems into plug-and-produce production ones based on Cyber-Physical Systems technologies. In particular, this paper aims at describing a methodology leading to identification and deployment of general business and strategic requirements needed to implement new plug-and-produce paradigms into traditional production systems. This approach mainly based on the Requirement Engineering methodology (RE) also leads to the identification of an appropriate set of KPIs (technical and business) able to measure and to benchmark collected requirements. Four Industrial Use Cases have been analyzed, taking the CPS-5C architecture as reference model to map their AS-IS and TO-BE situations with respect to their CPS attitude, confirming the possibility to use this approach among different manufacturing sectors, for large companies, SMEs as well as for new and existing small plants.

IECON 2016: Exploring the integration of the human as a flexibility factor in CPS enabled manufacturing environments: methodology and results
Cyber Physical Systems (CPS) are expected to shape the evolution of production towards the fourth industrial revolution named Industry 4.0. The increasing integration of manufacturing processes and the strengthening of the autonomous capabilities of manufacturing systems make investigating the role of humans a primary research objective in view of emerging social and demographic megatrends. Understanding how the employees can be better integrated to enable increased flexibility in manufacturing systems is a prerequisite to allow technological solutions, as well as humans, to harness their full potential. Humans can supervise and adjust the settings, be a source of knowledge and competences, can diagnose situations, take decisions and several other activities influencing manufacturing performances, overall providing additional degrees of freedom to the systems. This paper, studies two different integration models: Human-in-the-Loop and Human-in-the-Mesh. They are both analysed in the context of four industrial cases of deployment of cyber physical systems in production.
