现代仓储中心存储布局的优化研究

Study on Storage Layout Optimization of Modern Warehouse Center

仓储中心的货架摆放布局是影响拣选作业效率的重要因素之一,为研究货架摆放布局对有效存储面积的影响,以鱼骨布局为研究对象,构建其有效存储面积利用率模型,并对其进行仿真验证。结果表明,在鱼骨布局设计的仓库中,主拣选通道角度一定时,拣选通道宽度与货架宽度比例越大,有效存储面积利用率越小;拣选通道宽度与货架宽度比例一定时,主拣选通道角度越趋近于0度或者90度时,有效存储面积利用率越大。由此,鱼骨布局等改进型仓储布局为决策拣选路径提供了新的思路,也从理论上证明了改进型仓储布局实践应用的可行性。

The layout of shelves in the storage center is one of the important factors affecting the efficiency of picking operation.In order to study the impact of layout of shelves on the effective storage area,the Fishbone layout is chosen as the research object,an estimation model of the proportion of effective storage area is constructed and verified by simulation.The results show that when the angle of the main picking channel is fixed,the larger the ratio of the picking channel width to the shelf width,the smaller the utilization of the effective storage area,when the ratio of the picking channel width to the shelf width is fixed,the more the angle of the main picking channel approaches 0 degree or 90 degrees,the greater the utilization of the effective storage area.Therefore,the improved storage layout such as the Fishbone layout provides a new way for decision-making in picking operation,and also proves the feasibility of the practical application of the improved storage warehouse layout.
