A centralized support infrastructure (CSI) to manage CPS digital twin, towards the synchronization between CPS deployed on the shopfloor and their digital representation

Abstract

In order to support effective multi-disciplinary simulation tools in all phases of the factory life cycle, it is mandatory to ensure that the Digital Twin mirrors constantly and faithfully the state of the CPS. CPS nameplate values change over time due to situation and strain. Thereupon, this chapter describes the future CPS as equipped with special assets named Functional Models to be uploaded to CSI for synchronization and data analysis. Functional Models are essentially software routines that are run against data sent by the CPS. Such routines can regularly update CPS reference values, estimate indirect metrics, or train predictive models. Functional Models are fully managed (registered, executed, and monitored) by the CSI middleware.
