Warehouses are essential to manufacturing. They do more than just store materials. A properly managed warehouse enables manufacturers to ensure that materials and parts are present, identifiable, secure, and supplied in the right place at the right time.
Knowing how warehouses work is crucial to understanding production logistics.
What Is the Purpose of a Production Warehouse?
A production warehouse bridges the gap between inbound goods and manufacturing.
Goods might be received from a supplier, sit in the warehouse for a period, and then be moved to a production line according to a production schedule.
Thus, the warehouse must fulfill two main goals: ensure material availability and avoid excessive stockpiling.
Receiving Goods
Warehouse activity starts when goods are delivered.
Receiving staff usually inspect the quantity, the item identification, the condition of the packaging, and any related paperwork.
It’s important to get these details right, since mistakes made during receiving can lead to wrong records in the inventory, and eventually lead to problems with production.
Storing Goods
How goods are stored can have a big impact on the efficiency of the warehouse.
Ideally, every product should have a fixed location and items that are used regularly should be kept in a place that allows quick access.
Depending on the nature of the product, storage may also depend on the size of the goods, the weight, how they are handled, or the environment in which they need to be kept.
Maintaining Inventory Records
A warehouse cannot support production if the inventory records are not accurate.
If the actual amount of a material in the warehouse differs from what is shown in the system, production planners will make decisions based on inaccurate data.
To reduce these errors, regular counts and timely updates on material transactions should be done.
Picking Goods
Picking refers to the process of gathering the goods that are required for a specific production order or process.
In a well-run picking process, the correct goods and the correct amount are gathered and delivered to the designated place.
Mistakes in picking can lead to delays in production, incorrect assembly of parts, additional handling, or simply wasted time.
Moving Goods Within the Warehouse
Once the goods are picked, they need to be moved to the production floor.
Transporting goods within a warehouse can be done manually, by trolley, by forklift, by conveyor, by robotic equipment or any other means.
However, the objective of transporting goods isn’t only speed. It’s also important to ensure that goods are moved safely, orderly, and in accordance with production needs.
Supporting Just-in-Time Production
Some production processes try to keep minimal stock levels and supply materials as close to when they are needed as possible.
Such a process requires close cooperation among suppliers, warehouses, production planners, and the production team.
When deliveries are timed precisely to match the production schedule, companies can reduce their storage needs and excess stock.
But, such a process is only possible when the production and supply chain can be reliably planned.
Warehouse Design
The design of a warehouse can have a significant impact on how quickly staff and equipment can move around.
A poorly designed warehouse can lead to long travel distances, congestion, excessive handling, or difficulty finding goods.
The design of the warehouse should consider the flow of goods, the capacity of the warehouse, the accessibility requirements, the safety requirements, and the frequency of use of various products.
Technology in Warehousing
Many modern warehouses are equipped with technological solutions that increase visibility and control.
A warehouse management system can be used to manage stock locations, amounts, movements, and orders.
In addition, technologies such as barcode scanners, RFID tags, automated storage and retrieval systems, and up-to-the-minute inventory data can help make the warehouse more efficient and require less manual effort.
These technologies are particularly helpful when the warehouse deals with a large number of items or high volumes of movement.
Ensuring Safety in the Production Warehouse
A warehouse should be efficient, but safety should never be compromised.
Goods should be properly stored, transportation paths should be clear, and handling equipment should be used correctly.
Employees should also know how to safely lift, transport, store, and handle the various kinds of goods.
A safe warehouse is an integral part of a successful production operation.
Tracking Warehouse Efficiency
The efficiency of a warehouse can be measured by several metrics.
Some examples are:
- Inventory accuracy
- Order picking accuracy
- Stock retrieval time
- Space utilization
- Internal transport time
- Number of mistakes
Such metrics can be used to find areas where problems exist and determine which areas could use improvement.
The Warehouse as Part of the Production Process
The warehouse does not operate in isolation.
It is part of procurement, inventory management, production scheduling, internal transport, and ultimately production itself.
Without proper coordination in the warehouse, even a well-planned production schedule will fail.
For this reason, warehouse management is best seen as part of production logistics.
Conclusion
Proper warehouse management makes sure that goods are available, well-organized, traceable, and supplied to the right place at the right time.
The objective of a warehouse is not only to hold as much as possible. It’s about managing the movement of goods through the warehouse so that they are stored correctly and transported efficiently to production.
A warehouse is only as good as its ability to support the flow of production, rather than simply holding inventory.
