Redundant and decentralised directory facilitator for resilient plug and produce cyber physical production systems

Cyber Physical Production Systems (CPSS) build on the concept of “Plug-and-Produce” aiming to deliver truly agile production systems. These systems are modular by nature and can be adapted based on changing requirements. One of the challenges in this domain is how to store and propagate information within CPPS. In this paper, a Redundant and Decentralised Directory Facilitator will be introduced to provide the capability to store and broadcast the existing system assembly capabilities. Additionally, this solution will provide redundancy and delocalization of the assembly capabilities information. The model used is described, as well as interactions, behaviours and deployment strategies. Finally a validation scenario is presented and conclusions are presented.
