Shelter consumable reorder point

Use consumption and delivery delay to set a chosen stock trigger.

How it is calculated

Reorder threshold = round up(daily consumption × (lead-time days + buffer days)). Stock position = stock − threshold.

Assumptions & limits

Applies to one interchangeable consumable. A negative stock position indicates stock below the selected trigger; delivery and demand variability may require more cover. Defaults are illustrative planning inputs, not recommended minimums or a guarantee of safety.
