Every term the course uses, in plain words, with the lesson that teaches it.

A

Address — A bin's name, written row / bay / level, for example ROW-A01/B03/L2. Bays and levels count from 1. Bins and levels

Advisory — A readiness item that does not stop a run. The run assumes something and says so. Running the warehouse

Aisle — The lane in front of a rack row that a forklift drives along. Written A in a lay pattern. Racking 101

Apron — The yard space in front of a dock door where a truck backs up. Aisles, routes and roads

Assumed — A value nobody measured. A provenance, and a word the platform uses whenever it fills a gap. Operating profiles
