Choose the plan and its protection together.
What the evidence means
A resilient plan balances the costs represented in the model against service and risk constraints. Fresh challenge futures test the frozen plan; they do not prove protection against every possible event. A solver gap applies to the stated optimization model, and is not a guarantee of real-world performance. Scope and data must be validated before a demonstration.

Buy protection where it pays, not buffer everywhere.
Protection takes many forms: inventory in the right place, spare capacity on the bottleneck, a second source for one critical part, flexible terms, a hedge. Each protects against different risks, over a different horizon, at its own cost.
VYAN sizes and places inventory buffers across the network as part of the plan and shows what that protection costs beside the exposure it removes. Supplier flexibility and reserved capacity join the same choice as VYAN grows. Some risks are rationally left unprotected, because protecting them costs more than they put at risk.
The resilient plan gives up a little against perfect hindsight, and holds up where the others do not.
Test today's commitments by moving forward through the futures.
A capacity reservation made this month binds a line three months out. A purchase made now cannot be undone when the outlook changes. So VYAN moves today's commitments forward through possible futures and re-decides at each new state, using only the choices still open.
Only the decisions needed now are committed. Later choices stay open, as decisions to be made when their time comes.
