Abstract: Order-driven customized manufacturing enterprises face highly stochastic external demands with respect to variety, quantity, due time, and customization level. Meanwhile, disturbances within the manufacturing system such as the insertion of urgent orders and equipment failures, are inevitable. Consequently, the dynamic coordination and synchronization between production and logistics (PL) emerge as the key for the efficient operation of systems. A multi-dimensional optimal synchronization (SYNC) state-guided out-of-order synchronization for PL management and control is proposed, to address the collaborative optimization challenges confronted by flexible manufacturing systems in complex, uncertain environments. Firstly, inspired by the “Out-of-order execution (OoOE)” found in computer processors, the mapping relationship between processors and the operations of manufacturing systems is analyzed. An instruction-based OoOE synchronization mechanism for PL operations within smart manufacturing systems is developed. Subsequently, an out-of-order decision-making approach guided by a multi-dimensional optimal sync-state is designed. A PL optimization model focused on multi-dimensional synchronization is formulated and an improved multi-objective simulated annealing algorithm is designed to generate an initial instruction queue. Guided by the optimal sync-state, real-time data-driven multi-dimensional priority is designed to control instruction dispatch, facilitating dynamic adjustments to the execution order of PL operations and resource allocation in response to disturbances to ensure the real-time performance and resource utilization of the system. Experiment results from laboratory case studies demonstrate that the proposed method significantly enhances the efficiency and resilience of the system in complex uncertain scenarios, providing innovative insights and strategies for dynamic control and data-driven optimization within the realm of smart manufacturing.
