Forecast combinations under regime change

Advanced forecasting should be judged by horizon, segment and decision value—not one aggregate score. This note examines forecast combinations under regime change with that evaluation discipline.

Practitioner lens

Operational monitoring for forecast combinations under regime change should track residual patterns, input drift, interval coverage and performance by lifecycle state—not only a global score.

First experiment

Propagate predictive distributions into the downstream inventory or capacity decision where possible.

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