Cold Chain Loss Exposure at 65% temperature compliance yield: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop temperature compliance yield to 65%, then walk the calculation through step by step. Estimate releasable cold-chain units after shipment, excursion, and release losses for temperature-sensitive pharma or biotech products.

The inputs for this scenario

  • Cold-chain shipments or lots: 4 shipments (held at the documented default)
  • Units per shipment or lot: 480 units / shipment (held at the documented default)
  • Temperature compliance yield: 65 % (the input this scenario stresses; the baseline uses 90)
  • QA release yield after excursion review: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross capacity = Cold-chain shipments or lots × Units per shipment or lot.
  • Good output capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross cold-chain units works out to 1,920 units at these inputs.
  • Uptime loss works out to 672 units at these inputs.
  • Yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where temperature compliance yield sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to temperature compliance yield, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes independent, uniform yields across shipments — a single catastrophic excursion that wipes out a whole lot is not captured by average percentages.

Results at a glance

  • Good output capacity: 1,211 units (headline result)
  • Gross cold-chain units: 1,920 units
  • Uptime loss: 672 units
  • Yield loss: 37.44 units
