Abstract
The survival of original equipment manufacturers (OEMs) requires rapid responses to changing customer demands while keeping cost savings as their top priority. This paper proposes a Digital Twin (DT) enabled reconfiguration framework for the semi-automatic electronic assembly line with frequent changeovers. The DT platform develops an open architecture for the equipment and the assembly line to support its rapid physical reconfiguration, and a generalized knowledge encapsulation technique is applied to facilitate virtual reconfiguration. The dynamic performance is evaluated by max-plus semiring. Subsequently, an optimal reconfiguration algorithm via analytical target cascading, named minimal reconfiguration, is proposed to solve the coupled optimization of order scheduling, line balancing, and buffer allocation. A smart-phone assembly line is applied to verify the DT platform efficiency and minimal reconfiguration optimization approach.
