Packrift scenario model

Subscription Refill Orders: Single-unit order

Subscription orders are attractive packaging tests because quantities repeat. The package rule can be narrow and still affect meaningful volume. This single-order flow model uses 950 monthly orders and a DIM divisor of 139 to compare the current Multi-depth carton against smaller protective formats.

Decision read

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 8 x 5 x 2.8 in, 1.15 lb per unit, and 1 unit per order. The current package is 12 x 9 x 7 in with 74 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.

Procurement rule

Candidate rule

Create separate rules for one-cycle, two-cycle, and family-plan quantities rather than letting one carton cover every subscription order.

Cost model

Assumptions used

$0.73 per billable pound.
$19.50 per warehouse labor hour.
1% current damage rate.
$34.00 expected replacement or support cost.
