Packrift scenario model
Marketplace Multi-SKU Bundles: Two-pack repeat order
Bundles are where average carton logic breaks down. The same master carton may work for operations while quietly adding cube to most orders. This repeat quantity band model uses 640 monthly orders and a DIM divisor of 139 to compare the current Corrugated carton against smaller protective formats.
What this scenario is testing
This version tests whether the second unit still nests efficiently or pushes the order back into carton territory. The model starts with an item profile of 10 x 7 x 3.36 in, 1.6 lb per unit, and 2 units per order. The current package is 15 x 11 x 9.2 in with 100 seconds of pack time.
Packrift treats the result as a screening recommendation. It is strong enough to prioritize a pilot, not strong enough to replace invoice analysis, damage tracking, or warehouse observation.
Candidate rule
Use fit screens to split stable bundles from exception-prone bundles before changing the pack rule.
Assumptions used
- $0.79 per billable pound.
- $20.50 per warehouse labor hour.
- 1.85% current damage rate.
- $40.00 expected replacement or support cost.
Risk checks
- SKU mix volatility
- pick sequence
- insert collisions
- exception rate
How to test it
- Tag orders with exactly two units.
- Record whether the second unit changes dunnage or fold behavior.
- Keep the rule separate from single-unit orders until variance is measured.
