ECRS和SLP在服装单件流工序排序中的应用

Application of ECRS and SLP in Scheduling One-piece Clothing Flow

针对中小型服装企业在实施单件流过程中不能有效解决生产线工序排序的问题,提出一种基于ECRS原则和SLP法的工序排序方法。首先利用ECRS原则对制约流水线生产能力的瓶颈工位和能力过剩工位进行分析与改进,其次采用SLP法在顺序因素和聚类因素的基础上划分出非物流关系程度等级,然后通过绘制物流相关表建立各工位与生产线之间的量化关联关系,并提出生产线工序排序方案,进行工序的平衡分配和工位的合理编排,最后采用Flexsim系统仿真验证该方案的可行性。通过实例验证表明,该方案在由捆包流向单件流转化过程中,可有效缩短物流距离,提高生产效率,且简单易行。

Aiming at the problem that operation sequencing could not be solved efficiently when the small and medium garment enterprises implemented one-piece flow, an operation sequencing method based on ECRS princi- ples and SLP method was proposed. Firstly, the bottleneck and excess capacity station restricting flow production lines were analyzed and improved by using ECRS principles. Secondly, degree of non-logistics relationship grade was classified in accordance with the SLP method based on sequential factors and clustering factors. Then, the quantitative relationship between the station and the producing line was established through drawing logistics related table. Producing line ordering scheme was put forward to balance the process and station. Finally, Flexsim simula- tion system was used to verify the feasibility. It can effectively shorten the logistics distance and improve the pro- duction in the process from bale flow to one-piece flow.
