As more and more businesses move into omni-channel distribution, the efficiency of ones inventory operation becomes relevant. But one may ask, when is a warehouse considered to be at capacity? The answer to this may vary, but typically a warehouse is at peak efficiency where space utilisation is at 80 - 85%. Breaching this threshold will see diminishing efficiency from a movement and space perspective. Pallet movement is restricted making each replenishment take more steps to complete, temporary storage of pallets on the floor will also inhibit efficiency. More steps to complete a move results in increased costs and slower processing, a business in this position will also have to expand to more locations quicker.
One of the first things to look at when assessing warehouse efficiency is by looking at each product on the shelves. In order to understand your specific situation, you need to assess the sell-through rate of each SKU sitting in inventory. This is the rate at which you sell through your entire inventory of a given SKU within a defined time period. Using this information, make an assessment on which products you may be overstocked on. With this in mind, here are some tips to make most efficient use of your warehouse.
Quantify the storage profile of your warehouse in terms of capacity and utilisation, look up and ensure you’re making best use of your vertical space. How many cubic meters of overhead space are not used? When discussing vertical space, make sure any changes you plan to make do not conflict with the fire safety installation of the building. While you’re on the subject of vertical space, identify functions where stacking heights are lower. It isn’t uncommon to observe empty upper rack space in areas of a warehouse where packing and dispatch take place. Another aspect of shelving that is often overlooked is depth, switch to double-depth racking to further increase efficiency.
If you are holding the same SKU across different bins or locations, try to consolidate these to increase space utilisation. Matching the size and sales of your different SKUs to an appropriate sized pick slot will also maximise the efficiency of your picking slots. If you find you’re overstocked on a couple of products, consider storing this inventory off-site to free up rack space for products with a high sell-through rate. Where possible, introducing drop-shipping for these products will further decrease your in-house inventory costs.
Another factor to consider is the width of your aisles, you don’t want these to be too wide as this will lower your overall space utilisation. By the same token you don’t want your aisles to be too narrow to the point where they inhibit picking equipment from operating effectively. Try to keep your inventory of packing materials relatively lean to retain space for other products. A good way to do this is by taking with your packaging supplier, aim to have them hold some inventory for you and simply take delivery every few days.
