Abstract: In order to solve the problem of customized workshop production-logistics collaborative dynamic scheduling, a completely-reactive scheduling cyber-physical system framework is proposed. On the basis of this framework, a "single-step" scheduling algorithm is proposed and a task priority calculation rule that comprehensively considers customer satisfaction, equipment utilization and energy consumption is designed. Because the "single-step" scheduling algorithm only considers the scheduling of the current production or logistics task each time, and the production-logistics collaboration ability is weak, so in order to make up this defect, a "double-step" scheduling algorithm that comprehensively considers the scheduling of production and logistics two-step task is proposed. The anti-disturbance mechanism was designed to enhance the anti-disturbance capability of the two algorithms. The simulation results show that the "single-step" scheduling algorithm is better than the traditional scheduling algorithm but not as good as the "double-step" scheduling algorithm. The latter can better allocate production and logistics resources under certain workshop disturbance, and perform particularly well in the index of "average advance/delay cost of job", and can better adapt to personalized customization scenarios.
