Packrift scenario model
Automotive Accessories: Long-zone DIM exposure
Automotive accessory savings can be misleading because dense hardware and sharp edges increase puncture, support, and reship risk. 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 12 x 5 x 3.2 in, 2.7 lb per unit, and 1 unit per order. The current package is 16 x 10 x 8 in with 96 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
Keep a corrugated reserve for hard automotive parts unless edges are capped and hardware is separately contained.
Assumptions used
- $1.18 per billable pound.
- $21.00 per warehouse labor hour.
- 2.1% current damage rate.
- $46.00 expected replacement or support cost.
Risk checks
- sharp brackets
- oil or residue
- hardware bag containment
- finish scuffing
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.
