摘要
针对服装生产线员工变动频繁、技能熟练度不一致以及设备布局受限等造成的流水线部件逆流和不平衡问题,提出了一种基于先验算法的服装生产工序组合关联规则挖掘方法,以优化流水线设计.根据服装工艺和生产特点提出了工序编码方法,通过改进Apriori算法来挖掘用于流水排布的生产工序关联规则,建立了以逆流情况和流水线平衡为约束的评判指标,通过工序内容与评判指标进行流水线优化排布.结果表明:优化后的流水线完全避免了零部件在路径上的传递损失,流水线的排布效率提高了 20％,线内工位平均均衡比相较于原有产线提高了 20％,排布内容更切合工厂生产实际环境和经验要求.使用该方法挖掘工序关联组合具有较好的可靠性,工序组合的应用有利于提升流水线排布的实际意义.
Abstract
Aiming at the problems of countercurrent and unbalance of assembly line components caused by frequent staff changes,inconsistent skill proficiency and limited equipment layout in garment production line,a method of mining association rules for garment production process combination based on the Apriori algorithm was proposed to optimize assembly line design.Based on the clothing process and production characteristics,a process coding method was developed,Apriori algorithm was improved to mine the production process association rules used for flow arrangement,and an evaluation index constrained by countercurrent situation and pipeline balance was proposed.The optimization and layout of the assembly line were carried out by process content and evaluation index.The experimental data show that the optimized assembly line completely avoids the transmission loss of parts in the path,the layout efficiency of the assembly line is increased by 20％,the average balance of workstations on the production line is increased by 20％compared to the original production line,and the layout content is more in line with the actual production environment and experience requirements of the factory.To sum up,the mining process association combination using the method has good reliability,and the application of process combinations is of practical significance to improving the assembly line layout.
