仓储与配送科学-5.1.2 Bin-shelving or static rack

仓储与配送科学

Figure 5.2: Shelving, or static rack. (Adapted from “Warehouse Modernization and Layout Planning Guide”, Department of the Navy, Naval Supply Systems Command,NAVSUP Publication 529, March 1985, p 8–17.)

Simple shelving is the most basic storage mode and the least expensive (Figure 5.2).The shelves are shallow: 18 or 24 inches (0.46 or 0.61 meters) are typical, for example,but 36 inch (0.91 meter) deep shelf is sometimes used for larger cartons. Because the shelves are shallow, any signifificant quantity of a SKU must spread out along the pick-face. This reduces SKU-density and therefore tends to reduce pick density, increase travel time, and reduce picks/person-hour.

Skus which occupy more than one shelf of bin-shelving are candidates for storage in another mode that will enable greater SKU-density.

A typical pick rate from bin-shelving is 50–100 picks/person-hour. (Of course this and the pick rates for any equipment depends on which SKUs are stored there.)With shelving, both picking and restocking must be done from the pick-face and so, to avoid interference, must be scheduled at different times. This can mean working an additional shift.

5.1.2 搁板或静态货架

图5.2.搁板或静态货架。(引自“仓库现代化和布局规划指南”，海军部，海军供应系统司令部，NAVSUP出版物529,1985年3月，第8-17页)

简单的搁板货架，是最基础存储模式，而且也是最便宜的（图5.2).如图所示：典型的深度是18或24英寸(0.46或0.61米)，如果存更大箱子则有可能需要36英寸(0.91米)深。因为货架非常浅，将会需要沿着拣货工作面将一个SKU铺开，它将使SKU密度和拣货密度都会降低，行走时间增长，从而导致单位时间拣货次数减少。

如果采用让同一个SKU分散在多个货架中存放的模式，这将有助于提升SKU密度。

在搁板式货架中的拣货效率约为每小时50-100次（具体效率则依存储模式和所使用的设备而异）。因为搁板货架的拣货和上架需要在同一条通道中进行，则需要为这两种作业排出时间表，以免互相干扰。这有可能意味是需要安排一个额外的作业班次。
