Planning Physics Encyclopedia
Supply planning has physics. Zero-day planning needs them.
Supply planning is governed by repeatable laws — inventory, flow, lead time, capacity, constraint, commitment, and authority. This is the operator's reference to the concepts that make a plan reproducible, explainable, and usable when conditions change.

The plan is a connected system.
The concepts relate — supply becomes promiseable, promises become commitments, commitments become a governed planning record. Trace the connections.

Read the entry →A governed boundary that changes which actions are allowed as the need date approaches.
Read the entry →A governed buffer sized to absorb uncertainty at a defined service objective.
Read the entry →Every event by which future supply is reserved, promised, released, consumed, or superseded.
Read the entry →An agent whose evidence, tools, permissions, and state changes are explicit — authority follows the action.
Read the entry →A secure, time-ordered record of who or what changed planning data, decisions, and commitments.
