Maximizing space utilization is more critical than ever before; lean methodologies, cost-effectiveness, increased efficiency, and productivity are key drivers of operational improvement in material handling. Warehouse space often represents 15% to 20% of the cost per order and moving to new space is expensive and time-consuming. Follow the subsequent steps to calculate warehouse volume capacity and take the action to assign someone responsible for ongoing analysis.
Step 1: Calculate Warehouse Space Utilization for Material Handling
The optimal range of space utilization ratio is between 22%-27%. However, with automation, it’s possible to achieve higher densities. Use the steps to determine your current ratio.
- Find the total available square footage by SUBTRACTING the square footage of all offices, restrooms, and other non-storage areas.
- Determine the overhead height by ADDING the height of all steel beams, suspended lighting, overhead fans, or other mechanical equipment (also on blueprint)
- Calculate the warehouse available storage capacity (WASC) by MULTIPLYING available square footage x overhead height.
- Calculate the Warehouse Storage Cube (WSC) by MULTIPLYING the width and length of racks times the height the inventory that’s stored. Tip: Look at the Blueprint for rack size and/or measure the racks.
- Calculate warehouse space utilization by DIVIDING your WSC by your WASC :
Step 2: Identify Areas of Material Handling Improvement
Check all that apply:
- Do you use Vertical Space (Check with sprinkler design and fire code.)
- Are you utilizing your department space correctly? (Ex: move activities that don’t require high overhead ceiling height into areas with low ceilings.)
- Are inventories consolidated by type (Consider implementing a dedicated put-away process.)
- Do you match item sizes with accurately sized slots
- Do you use drop-shipping when storing and shipping large items
- Are you cross docking
- are you using the entire depth of your storage (Review not only the effective use of the height of locations and/or consider double-depth racking.)
- Are your shipping and receiving docks separate? (Consider combining shipping and receiving docks to save space.)
- Do you have a mezzanine? (Consider installing a mezzanine to house functions that do not require high-bay storage.)
- Reduce Inventory (Re-locate items that are not being sold at the anticipated velocity.)
How Automation can Help
Automation can increase the volume capacity by increasing the density of how totes/pallets are stored inside a facility, and some automation systems allow for new options in space utilization. For example, aisles may not require forklift-width or human-width sizing, as robotics and automation would pull cases from out behind others (depending on the system); thereby increasing the storage density. Automation can both be implemented in formerly human-centered storage spaces, or portions of existing facilities can be allocated to flexible robotic storage systems and AS/RS systems.
