Packrift scenario model
Pet Supply Refills: Long-zone DIM exposure
Pet refill orders repeat often enough to deserve narrow rules, but dense pouches and mixed accessories need separate damage and leak checks. This long-zone dimensional-weight pressure model uses 520 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 stresses carrier cost by modeling a higher landed rate per billable pound, which makes cube reduction more important than material savings alone. The model starts with an item profile of 10 x 7 x 3.8 in, 2.1 lb per unit, and 1 unit per order. The current package is 14 x 10 x 8 in with 86 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
- $1.18 per billable pound.
- $19.50 per warehouse labor hour.
- 1.5% 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
- Select a long-zone lane with repeated shipments.
- Compare carrier invoice billable weight against the modeled billable weight.
- Keep the package change lane-specific until invoice variance is understood.
