Packrift scenario model
Pet Supply Refills: Two-pack repeat order
Pet refill orders repeat often enough to deserve narrow rules, but dense pouches and mixed accessories need separate damage and leak checks. This repeat quantity band model uses 640 monthly orders and a DIM divisor of 139 to compare the current Multi-depth 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 4.26 in, 2.1 lb per unit, and 2 units per order. The current package is 14 x 10 x 9.2 in with 92 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
Create separate pet refill rules for dense pouches, light accessories, and mixed carts instead of one subscription carton rule.
Assumptions used
- $0.78 per billable pound.
- $19.50 per warehouse labor hour.
- 1.55% current damage rate.
- $36.00 expected replacement or support cost.
Risk checks
- pouch corner wear
- odor containment
- mixed accessory dents
- repeat-order quantity bands
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.
