How to use it
- Choose a crisis. Start with baseline, then close borders or the plant.
- Choose a policy. Reactive control is cheap; resilience requires a deliberate hedge.
- Run the twin. Watch material batches, factory status, backlog and cash move together.
- Compare evidence. Use the same seed to separate policy effects from random demand.

Run the compound crisis, then explain why the lowest-inventory policy may not be the cheapest policy.
The operations question
Resilience is a network property. A factory can have capacity and still stop when one critical component is trapped upstream; customer demand then converts operational delay into cash pressure.
The control logic
The control tower counts on-hand plus in-transit material, reallocates scarce FG by backlog severity and accelerates alternate lanes when a border is blocked.
Class challenge
- Keep service above 95%.
- Avoid negative cash.
- Explain the cost of each hedge.
