基于EIQ-ABC-SLP方法的钢铁物流园区仓储布局

Storage Layout of Steel Logistics Parks Based on EIQ-ABC-SLP Method

为了实现物流园区内仓储布局的合理性,针对当前钢铁物流园区普遍存在的仓位设置、堆场布局不合理,货场车辆流转时间长等问题,提出了一种整合的基于EIQ-ABC-SLP的钢铁物流园区仓储布局方法。首先通过历史订单资料的EIQ分析,找出货品出货数量和出货次数的特点,并据此对货品进行ABC分类,明确每类货品的出入库布局需求。其次应用SLP方法得到货品间的密切关系等级,明确货品相对位置布局需求。综合出入库布局需求和相对位置布局需求可得出具体的仓储布局方案。最后,将该方法应用于某钢铁物流园区的螺纹钢堆场布局,给出了布局方案,并与其他布局方案进行了对比。分析结果表明,使用EIQ-ABC-SLP方法得到的布局方案能有效减少车辆流转时间,提高堆场工作效率。

Reasonable layout in Logistics Parks is a key factor to efficient operations with low costs.To address widespread problems such as unreasonable positioning of warehousesand low transit efficiency of trucks in freight yards in steel Logistics Parks nowadays,an integrated planning method for steel Logistics Parks layout based on EIQ,ABC and SLP is proposed.Firstly,the EIQ analysis is conducted on the outbound data to find out the characteristics of shipment quantities and frequencies of goods,according to which the ABC classification of products is conducted and the shipment requirements of goods are determined.Then,the SLP is implemented to derive thelevels of closeness relationships among goods to find out the relative positioningrequirements of goods.The warehouselayoutplan can be worked out based on in/out requirements and relative positioning requirements.Finally,the method is applied to a real deformed steel bar yard in a Logistics Park.A comparative analysis is conducted and the results show that the integrated EIQ-ABC-SLP methodis an effective tool for Logistics Parks to speed up vehicle circulation andto improve operational efficiency in storage yards.
