Packrift scenario model

Marketplace Multi-SKU Bundles: Single-unit order

Bundles are where average carton logic breaks down. The same master carton may work for operations while quietly adding cube to most orders. This single-order flow model uses 950 monthly orders and a DIM divisor of 139 to compare the current Corrugated carton against smaller protective formats.

What this scenario is testing

This page isolates the simplest order shape so the savings case is not distorted by bundle exceptions. The model starts with an item profile of 10 x 7 x 3 in, 1.6 lb per unit, and 1 unit per order. The current package is 15 x 11 x 8 in with 88 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.
