许多仓库开槽算法忽略了工人的人体工程学。这项研究的目的是制定人体工程学开槽准则的基础上，背部和肩部的姿势和肌电图（EMG）的三角肌和竖脊肌肌肉的反应时，个别项目被选中，或完整的情况下补充，不同的货架高度在两项研究的第一项研究中，参与者解除小件物品代表件挑选任务从七个货架高度。在第二项研究中，参与者进行了一项模拟的整箱补货任务，他们将重量在2.7到10.9公斤之间的箱子从手推车上抬到流动货架上。货架高度显着影响所有的姿势和肌电图变量，并有一个权衡之间的背部和肩部肌肉活动在不同的货架高度。总之，这些研究被用来开发一些通用的人体工程学开槽指南，可以实施，以减少配送中心工人所经历的生物力学负荷暴露。
Many warehouse slotting algorithms have overlooked worker ergonomics. This research aimed to develop ergonomics slotting guidelines based upon the back and shoulder postures and electromyographic (EMG) responses of the deltoid and erector spinae muscles when individual items are picked from, or full cases replenished to, different shelf heights In the first study of two studies, participants lifted small items representative of piece-pick tasks from seven shelf heights. In the second study, participants performed a simulated full case replenishment task in which they lifted boxes weighing between 2.7 and 10.9 kg from a cart into a flow rack. Shelf height significantly affected all postural and EMG variables and there was a trade-off between back and shoulder muscle activity across the varying shelf heights. Together, these studies were used to develop some general ergonomic slotting guidelines that could be implemented to reduce biomechanical load exposures experienced by distribution center workers.
