Order Consolidation, Staging and Buffering

Order Consolidation, Staging and Buffering

Order consolidation, staging, and buffering are used in warehousing, distribution, and manufacturing environments for aggregating component parts into orders or kits for a manufacturing production run.

Benefits of Order Consolidation, Staging and Buffering

Order consolidation is the physical aggregation of so that they can be kept in a staging area. For example, a kit can have parts coming from a variety of different areas, and those components are typically picked into some kind of a tote with a license plate identifier. Order consolidation is commonly guided by some kind of automation, such as put by light (i.e., put wall), put by mobile device, or put into a carousel system.

Staging is the accumulation of the goods or parts until the order is completed and it is pulled. Staging may involve different staging locations, as well as different types of automation, such as flow rack, shelving, carousels, and standard racking. In some cases, the staged parts are inducted and pulled with only a mobile device or inducted with a mobile device and pulled with light-directed operations. In other cases, the parts are staged using a hybrid solution that involves a horizontal carousel, vertical carousel, or vertical lift module (VLM).

Buffering refers to the process for joining up the picks from different zones or areas of a warehouse to complete the entire order or work order. Buffering is also referred to as an order buffering system, put wall, consolidation system, etc.

Order consolidation, staging, and buffering capabilities are important for distributors and manufacturers with high volume and high SKU count of goods or parts, where picking occurs in multiple areas and it is not practical to perform traditional pick and pass. These warehouses and distribution centers rely on parallel picking, where all the component parts of orders must be brought together from different areas within the warehouse or distribution center, and then staged prior to preparation for packing, shipping, and/or truck loading. Without a system to direct and automate order consolidation, staging, and buffering, these processes can be slow, error-prone, and labor intensive.  

 

 

Automation optimizes order consolidation, staging, and buffering

Manual identification of parts or goods from various areas is time-consuming and prone to error. The process can be automated with some form of pick to tote or license plate identifier to identify what’s been picked in a particular area. Automation like this typically requires a warehouse execution system (WES) or warehouse control system (WCS) to manage the process and control the associated automation. The WES/WCS manages the manual or automated storage system used to actually perform the staging, buffering, and then the pulling process.

Automating order consolidation, staging, and buffering can improve warehouse throughput and reduce labor. After the component parts of the orders are picked there is usually a very narrow window of time for them to be assembled for shipment and/or truck loading. If automation is not used for order consolidation then large amounts of peak labor need to be applied. It is very difficult to balance these workloads because the labor tends to be needed in a huge spike towards the end of the shift.

The best software solutions for order consolidation, staging, and buffering

Enterprise resource planning (ERP) systems and ERP warehouse management software (WMS) modules, such as SAP and Oracle, rarely handle order consolidation, staging, and buffering processes well. They also do not handle any process automation, whether it is put and pull by light or any form of vertical or horizontal carousel solution.

A warehouse execution system (WES) or warehouse control system (WCS) software solution manages not only the communication to light directed operations and/or carousels, but also the workflow and process improvement functionality to identify all the different component parts from the various areas in an automated fashion, without slow and cumbersome manual verification. A WES or WCS can pull all of these functions together and seamlessly integrate them with automation, such as put and pull by light, horizontal carousels, vertical carousels, vertical lift modules (VLMs).
