Dairy & Frozen Food Manufacturing worked example

Cold Storage Days with average cold-chain demand of 3,000 cases / day: a worked example

What does the result look like when average cold-chain demand reaches 3,000 cases / day? The full calculation is worked below with real intermediate numbers. Use it when cold storage days in dairy and frozen food manufacturing is being sized for a buffer or safety stock review.

The inputs for this scenario

  • Average cold-chain demand: 3,000 cases / day (raised for this scenario; the documented default is 1,200)
  • Production or replenishment lead time: 85 days (unchanged)
  • Cold storage safety stock: 1.1 cases (unchanged)

Working through the calculation

  • Applying the documented formula (Lead-time cold-chain demand = average cold-chain demand × production or replenishment lead time) to the inputs above produces each figure below.
  • At this operating point the engine returns 32.09 cases for protected days of supply, the number this scenario is built around.
  • At this operating point the engine returns 35.29 days for unprotected days.
  • At this operating point the engine returns 3,000 pieces for inventory.
  • At this operating point the engine returns 85 pieces / day for daily usage.

How this compares with the baseline

  • Against the tool's baseline example, where average cold-chain demand sits at 1,200 cases / day and the headline result is 12.83 cases, this scenario comes in 150% above the baseline at 32.09 cases.
  • A figure at this level is achievable when average cold-chain demand is genuinely sustained, not just peaked for a shift. It assumes steady average demand; seasonal frozen spikes (summer ice cream, holiday pies) can blow through a buffer sized on the annual average.

Results at a glance

  • Protected days of supply: 32.09 cases (headline result)
  • Unprotected days: 35.29 days
  • Inventory: 3,000 pieces
  • Daily usage: 85 pieces / day
