摘　　要：目前印染车间作业计划还是依靠人工经验和软件辅助来安排,而不是通过建立数学模型描述生产过程和求解获得的,所以非常耗时,作业计划的生产效率低,甚至不能满足订单的交货期.文中提出了包含染色机清洗的印染生产过程优化调度数学模型,建立产品加工,工序,设备和交货期等的约束,以最大程度满足订单交货期为目标函数.不论订单有多少,印染生产过程有几条生产线,同一生产工序有几种生产设备,该模型都能满足印染生产过程调度的要求,只是数据文件的大小和模型求解的复杂度不同.以印染企业的5个订单为案例,通过ILOG CPLEX软件求解调度模型,获得订单车间作业计划.研究结果表明,生产的安排满足了订单的交货期,染色机只清洗了一次,模型的求解时间为秒级,极大地提高了印染车间作业计划安排的精确和效率.At present,the workshop schedule of the printing and dyeing enterprises still relies on manual experience and software assistance to complete,rather than establishing mathematical models to describe the production process and solve it,which is very time-consuming.Also the production efficiency of the workshop schedule is low,and it cannot even meet the due date of orders.This paper proposes a mathematical model for optimizing the scheduling of printing and dyeing production processes,including dyeing machine cleaning.The model adopts continuous time modeling to establish constraints on product processing,processes,equipment,and delivery time,with the objective function of maximizing order delivery time.No matter how many orders there are,how many production lines there are in the printing and dyeing production process,and how many production equipment there are in the same production stage,this model can meet the requirements of printing and dyeing production process scheduling,but the size of the datafile and the complexity of the model solution are different.In case study,taking 5 orders,equipment,and a production line of a printing and dyeing enterprise as a case,get orders,equipment,and process data from the information system of printing&dyeing enterprise to form a datafile,describe the mathematical model using ILOG CPLEX OPL language,CPLEX is used to solve the OPL model obtain workshop schedule,The research results indicate that the workshop schedule meets the due dates of the 5 orders,and the dyeing machine was only cleaned once.The solving time of the model is in seconds,which greatly improves the accuracy and efficiency of the printing and dyeing workshop scheduling.
