Combining a large number of orders into one wave does not necessarily reduce picking time. Order cut-off time, warehouse area, product characteristics and review capabilities will all affect grouping. WMS wave design needs to consider both picking and subsequent packaging to avoid centralized completion of the front stage and accumulation and waiting in the back stage.

How to arrange records and operations

Group rules save applicable order range and priority, and check inventory availability status before generating tasks. Out-of-stock orders are allowed to be processed individually, and allocated inventory cannot be freely occupied by another wave. When manually splitting waves, the original order relationship is retained, and the review is still based on the order requirements.

Before releasing a wave, you can check the task scale by warehouse area, order deadline and operating equipment. Out-of-stock orders should not be silently mixed into the normal picking queue. Shortage lines and processing arrangements should be displayed. When the picking task has been picked up, the execution personnel need to be notified to cancel the wave and register where the physical objects are placed. The re-picking task is associated with the original order and the original difference, and cannot increase the shipment quantity. During the test, two people were asked to receive tasks at the same time to check whether the task ownership and the picked quantity were consistent.

Specific scenarios that need to be checked

For example, if the same wave includes fragile goods and general goods, you should check whether zone picking and separate packaging are required. Test order cancellations, partial completion of tasks, and replenishment delays to observe whether tasks can be safely released or continued. When evaluating, check for mispicks, waits, and repeated walks at the same time to avoid pursuing only wave size.
