Abstract: Based on the idea of collaborative optimization of production planning and scheduling，a rolling optimization model of planning and scheduling was established，and a “closed-loop integration - rolling rescheduling” strategy was proposed. When the production system had dynamic changes such as capacity constraints or order changes，the scheduling and planning formed a “closed-loop response mode”，and further used the dynamic constraint balancing hybrid algorithm to optimize the production planning and scheduling. In order to verify the effectiveness and feasibility of the proposed cooperative optimization strategy，a typical example was selected for simulation. The results show that the strategy may effectively deal with the dynamic changes of the production system，and ensure the timely adjustment of the system scheduling optimization.

摘要： 基于生产计划与调度协同优化的思路，建立了计划与调度滚动优化模型，并提出一种 “闭环集成滚动重调度”策略。当生产系统出现产能受限或订单变更等动态变化时，调度与计划形成“闭环响应模式”，进而采用动态约束平衡的混合算法对生产计划与调度进行协同优化。为验证所提出协同优化策略的有效性和可行性，选取典型算例进行了仿真研究，结果表明该策略能有效处理生产系统的动态变化，保证系统的调度优化及时调整。
