QHAR: Q-Holonic-Based ARchitecture for Self-Configuration of Cyber–Physical Production Systems

open access: yesApplied Sciences, 2021
Production systems must be able to adapt to increasingly frequent internal and external changes. Cyber-Physical Production Systems (CPPS), thanks to their potential capacity for self-reconfiguration, can cope with this need for adaptation.
