Packrift scenario model
Subscription Refill Orders: High-volume pick line
Subscription orders are attractive packaging tests because quantities repeat. The package rule can be narrow and still affect meaningful volume. This labor-heavy warehouse lane model uses 2,400 monthly orders and a DIM divisor of 139 to compare the current Multi-depth carton against smaller protective formats.
What this scenario is testing
This version gives more weight to pack-station time because small seconds-per-order changes compound at volume. 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 92 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
Create separate rules for one-cycle, two-cycle, and family-plan quantities rather than letting one carton cover every subscription order.
Assumptions used
- $0.73 per billable pound.
- $19.50 per warehouse labor hour.
- 1.05% current damage rate.
- $34.00 expected replacement or support cost.
Risk checks
- quantity bands
- insert cadence
- return rate
- fulfillment rule accuracy
How to test it
- Time ten consecutive orders in the current package.
- Time ten consecutive orders in the test package.
- Watch whether label placement or sealing changes the apparent labor win.
