Cold-Chain Shipper Cost at 99% in-spec arrival rate: a worked example

Push in-spec arrival rate up to 99% and the picture changes. This example computes every intermediate figure at that operating point. A specialty distributor planning a 2-8C vaccine shipment uses it to size insulated shipper and gel-pack cost against the in-spec delivery rate.

The inputs for this scenario

  • Cold-chain shippers packed out: 800 shippers (unchanged)
  • Shipper plus coolant (PCM/gel) cost: 46 $/shipper (unchanged)
  • In-spec (temperature-compliant) arrival rate: 99 % (raised for this scenario; the documented default is 98)
  • Pack-out qualification and validation cost: 1,200 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total shipper cost = shippers packed x shipper & coolant cost x in-spec arrival rate% + validation) to the inputs above produces each figure below.
  • At this operating point the engine returns 37,632 $ for total cold-chain shipper cost, the number this scenario is built around.
  • At this operating point the engine returns 47.04 $ / piece for cold-chain shipper cost per unit.
  • At this operating point the engine returns 36,432 $ for variable cold-chain shipper cost.
  • At this operating point the engine returns 1,200 $ for fixed cold-chain shipper cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where in-spec arrival rate sits at 98% and the headline result is 37,264 $, this scenario comes in 0.99% above the baseline at 37,632 $.
  • It multiplies shippers packed by per-shipper cost and the in-spec arrival factor, adds the fixed validation cost for total cost, then divides by shippers for cost per shipper. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
