摘　　要：为了研究印染生产过程的优化问题,分析包括烧毛在内的前处理工艺、染色工艺和后整理的整个印染生产工艺,得出染色工艺是整个印染生产过程优化调度的关键.针对染色工序,建立单阶段的基于直接前后序的连续时间混合线性整数规划(MILP)优化调度模型.该模型考虑有直接前后序加工关系印染产品颜色的深浅关系和这2个产品切换生产成本的因素,调度目标包括提前完工和延期完工惩罚因素.根据给出的案例,利用ILOG公司的求解器对模型求解.调度结果的甘特图表明,通过对染色机生产的优化调度,整个印染生产过程的各种资源得到优化,提高了生产效率,降低了库存成本.The stage with pre-finish starting at singeing,dyeing and post-finish was analyzed to study the optimized scheduling of printing and dyeing process.Dyeing is a key stage for the printing and dyeing process.A novel single stage,continuous-time and immediate batch precedence based mixed integer linear programming（MILP） mathematical model was proposed for the dyeing stage.The color relation for the products with immediate batch precedence was considered,as well as the switching cost between the two products.The objective of the scheduling included the penalty coefficients of early and tardy completion.After solving a case with the solver of ILOG Company,Gantt chart for the scheduling results indicated that the resources of printing and dyeing process were optimized by the optimized scheduling of dyeing stage.The productivity was improved,and the inventory cost was reduced.
