摘要： 针对涤纶短纤维生产中纺丝组件更换周期调度问题建立了一个优化模型,以保证在给定的生产计划期内包括纺丝组件的使用费用和更换费用在内的总消耗最小.将纺丝组件更换调度问题归结为设备更新问题:纺丝组件相当于设备,组件的运行天数相当于设备役龄;用动态规划方法给出了该模型的最优解.利用某大型石化企业的实际数据对模型进行了仿真,并与现有的经验方法进行了比较分析.结果表明,上述方法能使生产费用平均降低6%～10%,从而证明了该方法的有效性和实际应用价值.

Abstract: In a polyester staple fibre plant the spin pack is one of the key facilities in the process of polyester staple spinning and its performance directly affects the productivity and fibre quality. The spin packs have to be replaced periodically. The problem is to determine the time that the spin packs should be replaced so as to minimize the total cost in a given planned period, including the operating cost and replacement cost. As an equipment updating problem, it is modeled with a dynamic programming (DP) method given to solve it. The model and algorithm are applied to the actual data collected from a large-scale petrochemistry plant, and the computational results are compared to the data generated manually in the plant to verify the effectiveness of the proposed method. It is found that 6%-10% of the total cost is saved on average.
