Packrift scenario model
Craft And Hobby Kits: Long-zone DIM exposure
Kit orders are sensitive to rattling and missing components. A packaging win should preserve part containment, not only reduce cube. 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 9.5 x 6.5 x 2.1 in, 0.95 lb per unit, and 1 unit per order. The current package is 13 x 10 x 6 in with 84 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
Only downshift kit orders after the component bag or insert prevents movement inside the smaller package.
Assumptions used
- $1.18 per billable pound.
- $20.00 per warehouse labor hour.
- 1.7% current damage rate.
- $29.00 expected replacement or support cost.
Risk checks
- small-part escape
- bag seal strength
- insert collisions
- kit presentation
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.
