Dependency X-Ray
Network Atlas · synthetic supplier study
Three suppliers. Two share one dependency.
Three suppliers can look like three alternatives until you follow the parts upstream. A and B both depend on X; C has a separate route. If X stops, how much of the order can still be filled?
Start with X selected, then add the Y → A bypass. It creates another path but delivers zero units per week. Watch the required-path reading change while the capacity shortfall stays the same. A connection tells you where something could travel; the capacity tells you how much can get through.
- Current allocation exposed to X
- 75%
- Demand shortfall if X is unavailable
- 70%
- Additional independent units/week for 70% output
- 4,000
Blue brackets mark required ancestry in the full admitted graph. They are separate from the directed links.

X is required for:A, B.
No admitted path to A avoids X.
Excluding X removes all admitted paths to:A, B, X.
Capacity reading:3,000 units/week remain under the stated no-inventory X-outage scenario.A path through C prevents X from dominating the product.

Boundary endpoints remain in the matrix when the branch closes. Empty cells indicate no admitted edge, not independent suppliers.
The 75% exposure is an allocation share, not an outage probability. The capacity scenario assumes one fungible component, no inventory, and expansion of C to 3,000 units/week.
