Abstract
En 中文
• This study is the first to explore digital twin-driven online optimization for smart reconfigurable manufacturing systems with human-robot collaboration while jointly considering manufacturing flexibility, position flexibility, and human-robot configuration flexibility. • A novel markov decision process is constructed for smart reconfigurable manufacturing systems with human-robot collaboration, featuring an order size-independent state representation with strong generalization, and a rule-based action set with explicit semantics and computability. A normalized Tchebycheff reward aggregation method is employed to simultaneously optimize enterprise-level objectives (Makespan) and human-centered objectives (human balance index). • A multi-agent collaborative online optimization mechanism is proposed, and its advantages in scalability, fault tolerance, and local disturbance isolation over single-agent approaches are demonstrated. • A multi-objective multi-agent twin delayed deep deterministic policy gradient algorithm (MO-MATD3) is designed, extending dual critics, delayed updates, and target policy smoothing to multi-objective and multi-agent scenarios.
