Time-expanded network design

A method that performs well on average may still fail at the tail. This note examines time-expanded network design with attention to stress cases, feasibility and operational control.

Practitioner lens

Uncertainty assumptions drive the behavior of time-expanded network design. Document how scenarios are generated, what dependencies they preserve and which low-probability cases deserve special attention.

First experiment

Separate model-generated proposals from approved actions; preserve a safe fallback when inputs are missing.

This is an original educational brief. It is a starting point for discussion, not a claim that one technique fits every supply chain.
