| Abstract: | This paper proposes a resilience dynamics modeling and control approach for a reconfigurable electronic assembly line under disruptions. A Digital Twin (DT) platform is developed as the basis for resilience analysis, and open reconfigurable architectures (ORAs) are introduced to support reconfiguration of the assembly line. The time-delays of disruptions are identified and used to characterize their spatio-temporal attributes. A systematic method based on max-plus algebra is proposed to model resilience dynamics under disruptions. The resilience control policy used in the DT platform is developed to minimize production losses, and it is tested on a smart phone assembly line, with its effectiveness validated by comparative analysis. |
