基于水资源节约的印染企业订单排序优化模型及应用

Order scheduling optimization for printing and dyeing enterprises aiming water conservation

针对印染过程中的主要耗水环节——染布清洗,运用过程优化思想,构建基于水资源消耗量最优的染布订单排序模型,并开发了基于动态生产的印染企业订单排序软件系统,在此基础上以某印染企业为对象进行了应用研究.结果表明:运用该系统对印染企业订单进行优化排序以后,在不对工艺和设备进行大量投资改造的情况下,印染企业可以在现有基础上节水20%-40%.

Printing and dyeing industry consumes huge water resource.Consequently,it discharges a great deal of wastewater containing complex pollutants which cause a heavy pollution.It is difficult to treat the discharge and the treatment cost is very high.Heavy pollution has been a great barrier for the sustainable development of the industry.The study examines the approaches minimizing water resource of dyeing-cleaning process which is one of the most water consuming processes.The research provides an optimization model for the order scheduling which can decrease the water consumption.Furthermore,the study develops software for order scheduling.On the base of above,the software is applied to a dyeing and printing enterprise.The result shows that it can reduce 20-40 percent of water consumption without any further investment in technologies and equipments.
