In this article we explain the meaning and define single-level picking in logistics or production.
What is single-stage picking?
Single-stage picking is a picking process in intralogistics in which an order is picked directly in the warehouse or in production. The picker (employee) goes to a storage location (in the storage zone) and picks the goods directly into a container, carton or box. The picking process is then completed in single-stage picking.
Single-stage order picking and conveyor technology
In logistics, partial orders are often picked in separate storage zones to improve picking performance. In the method, the process is also often supported with a conveyor technology to optimize the picking times (travel time). The picking of the items in the appropriate quantity takes place immediately and without intermediate steps. The picker works directly order-oriented at the storage location. The correct ABC analysis helps to optimize the handling costs.
Various picking methods, such as Pick-to-Light, Voice Picking, Pick-by-Point®, Pick-by-Cart, Pick-by-Frame®, etc., are used to support single-step picking.
