abstract
In the last years, many organizations intend to convert their existing production systems
towards ones that are characterized by adaptability, openness, flexibility and modularity. This
requires a redesign of existing information processing systems especially related to control,
leading possibly to the implementation of Cyber-Physical Production Systems (CPPS).
However, the implementation of new control technologies will have a direct impact on the
normal operational status of production while engineers will also face several challenges and
obstacles in adopting intelligent automation systems. New step-wise migration strategies are
required to holistically support industries in their journey towards CPPS taking into account
technical, economic and social aspects.
This work describes the definition of a migration approach for innovative production systems,
particularly those CPPS that are developed under the PERFoRM ecosystem, establishing
guidelines for a smooth migration from a traditional system to agile plug-and-produce systems
in a secure and efficient way. The designed migration approach comprises five phases,
namely Preparation, Options Investigation, Design, Implementation and Deployment,
sustained by three different migration strategies, namely One-Shot, Parallel and Phased. The
modelling of the migration process uses the Petri nets formalism taking advantage of its
inherent capabilities to synthesize the process specifications but also to verify, simulate and
validate the correctness of the system specifications during the design phase.
