Line-Down Clock

Objective

Answer one question per part number: how many hours until this plant stops. On-hand plus everything in transit, burned down at the rate the line consumes it. There is no model and no forecast here on purpose. Every number is arithmetic a plant manager can redo on a whiteboard, which is what makes it trustworthy at two in the morning.

Try this

1. Start on Normal production. Almost everything is covered past the 72 hour horizon: this is what healthy looks like.
2. Switch to Lean inventory. Roughly five parts drop inside 12 hours and the network first-stop lands near four hours.
3. Switch to New model launch ramp. Two parts go critical, and both are JIS sequenced parts, which is the real-world pattern.
4. Click a different plant card to load its board. Each plant has its own line rate, so the same stock buys different time.
5. Use At risk only to strip the board down to what needs a decision now.

What to look for

• Burn per hour is line rate times per-vehicle usage. A line at 18/hour running 8 drive tires per truck burns 144 tires an hour.
• Cover ignores in-transit; stops at folds it in. When they differ sharply, a truck is the only thing keeping the line running.
• Downtime 72h is total starved hours, not the first stop. Two parts that both stop at four hours can deserve very different responses.
• The driving part on each plant card is the one constraint that actually decides when the plant stops.
