Piecewise-linear approximation for planning

Advanced planning methods are only useful when they improve a real decision under real constraints. Here, piecewise-linear approximation for planning is framed as a testable system-design choice.

Practitioner lens

Separate prediction from action in piecewise-linear approximation for planning: identify what is estimated, what is optimized and which business rules must remain binding regardless of model confidence.

First experiment

Test the method at the level where the decision is executed, then inspect how aggregation changes results.

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