Resilience in Industry 4.0 Digital Infrastructures and Platforms Daniel RIBEIRO a,b, 1 , António ALMEIDA a,b , Américo AZEVEDO a,b and Filipe FERREIRA b a Faculdade de Engenharia, University of Porto, 4200-465 Porto, Portugal b INESC TEC—Institute for Systems and Computer Engineering, Technology and Science, 4200-465 Porto, Portugal Abstract. We live in a world where companies are shifting to the industry 4.0 paradigm. One of the pillars of Industry 4.0 is the digitalization of physical assets and manufacturing processes, moving toward the Cyber-Physical Production Systems concept (CPPS). In these systems, every component of the production process - machines, tools, workstations, etc. - is equipped with sensors, possesses information about itself, and can interact with each other, allowing the production of smaller batches at lower prices and increase product customization through adaptative processes. Consequently, companies are evolving their information systems to have more visibility and control over their production systems. This change increases both the production system’s agility and its vulnerability to communication and information related disruptions. Hence, companies that adhere to Industry 4.0 enabling technologies must adopt new methodologies and tools to become aware of the new risks that arise by the introduction of new digital platforms, their impacts in the production systems, and how they may react to remain resilient. In this paper, disruption events and adequate mitigation strategies are analysed, modelled, and simulated as part of a methodology designed to measure the impacts of disruptive events on the production system.

Introduction Industry 4.0 consists of a paradigm shift from automated production to an intelligent production concept where all physical assets such as products, components, workstations, and machines possess individual information about themselves and are part of a network with communication interfaces, where all participants can interact with each other using technologies such as the Internet of Things. These assets are now called Cyber-Physical Systems (CPS), and the manufacturing system itself a Cyber-Physical Production System (CPPS). CPPSs are highly flexible systems that allow small batches to be produced at lower prices and increase product customization through adaptive production processes [1]. Consequently, companies are evolving their information systems to have more visibility and control over their production systems. As an example, companies are 1 Corresponding author, E-mail: daniel.s.ribeiro@inesctec.pt. Advances in Manufacturing Technology XXXIV M. Shafik and K. Case (Eds.) © 2021 The authors and IOS Press.
