Valve Spare Parts Inventory Capacity at 61% storage utilization rate: a worked example

This worked example runs the valve spare parts inventory capacity numbers for a tougher week than the baseline: 61% storage utilization rate instead of the typical 85%. Calculate effective spare parts stocking capacity for valve inventory based on warehouse bin positions per aisle, available aisles, storage utilization, and inventory accuracy rate.

The inputs for this scenario

  • Bin positions per aisle: 60 positions / aisle (held at the documented default)
  • Aisles available for valve spares: 8 aisles (held at the documented default)
  • Storage utilization rate: 61 % (the input this scenario stresses; the baseline uses 85)
  • Inventory accuracy rate: 95 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross bin capacity = bin positions per aisle x aisles available.
  • Effective SKU stocking capacity works out to 278 SKUs at these inputs, and this is the headline figure for the scenario.
  • Gross bin positions available works out to 480 SKUs at these inputs.
  • Positions lost to utilization limits works out to 187 SKUs at these inputs.
  • Positions lost to inventory inaccuracy works out to 14.64 SKUs at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where storage utilization rate sits at 85% and the headline result is 388 SKUs, this scenario comes in 28.24% below the baseline at 278 SKUs.
  • Use it when sizing a spares store, deciding whether to add racking, or setting a SKU cap before introducing new stock items. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Effective SKU stocking capacity: 278 SKUs (headline result)
  • Gross bin positions available: 480 SKUs
  • Positions lost to utilization limits: 187 SKUs
  • Positions lost to inventory inaccuracy: 14.64 SKUs
