Packrift scenario model
Light Bulky Home Goods: Long-zone DIM exposure
Light bulky items usually show savings in billable weight before material cost. Cutting cube is the primary lever. This long-zone dimensional-weight pressure model uses 520 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 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 18 x 12 x 4 in, 2.2 lb per unit, and 1 unit per order. The current package is 24 x 18 x 12 in with 114 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
Prioritize carton-size reduction before changing package family when a product is bulky but still crush sensitive.
Assumptions used
- $1.18 per billable pound.
- $21.00 per warehouse labor hour.
- 1.7% current damage rate.
- $48.00 expected replacement or support cost.
Risk checks
- length-plus-girth
- surface scuffing
- oversize surcharge triggers
- void-fill waste
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.
