Stack inventory
Log yard inventory, counted stack by stack
In Atlas, yard stock is a set of stacks, and each stack is a list of measured logs. The count and the volume of a stack come from the logs in it, and its weight from the recorded weights of the delivery notes that brought them, so the figure the office reads is the figure the yard can show.
One yard, one length, one species
A stack holds logs of one yard, one length and one species. That rule keeps every stack a clean unit of stock: it can be counted, sold and loaded without sorting it again.
The logs reach a stack from the delivery notes of the trucks that brought them, already measured on the handheld, one reading per log.
What each stack shows
Open a stack and its figures are there, worked out from its logs and their delivery notes rather than typed in:
- Log count.
- Volume in m³.
- Weight in tonnes.
- Density, in tonnes per m³.
- Stock age, so the oldest wood is easy to find.
Build, move and merge stacks
Yard operators build stacks, move them and verify them. When two stacks fit together, they merge into one. When stock changes place, a stack moves to another yard.
Remnants from different stacks can be combined into one stack, so small leftovers do not turn into a scatter of half-empty piles.
Loaded logs, counted from what stays
After loading, the logs left in a stack are scanned as remnants. The loaded logs are the stack's logs minus its remnants, so nobody has to scan every log as it is loaded to know what left.
The remnants keep their own tags, and can be combined with the remnants of other stacks.
Audits that re-measure the stack
A stack can be audited. The auditor re-measures it and can add a photo, so the stack's figures are checked against the logs themselves.
Yard operators, auditors and warehouse admins work from the same stack records, so a question about stock gets one answer instead of three spreadsheets.
From the stack figure back to the truck
Every log in a stack keeps its tag, SED, length, species and origin forest. A stack figure traces back to the delivery notes and trucks that brought its logs, which is what a buyer or an auditor asks for.
