Editorial Standards
How accuracy, safety, sources and consolidation are handled.
Material-flow first
Guides distinguish mass flow, inventory, dwell, route capacity, equipment availability and service reliability so one metric does not stand in for the whole logistics system.
Primary sources
Safety context is checked against OSHA, U.S. freight-rail context against FRA/FHWA, digital-twin context against NIST, and advertising/privacy requirements against official Google documentation.
Safety boundary
No conveyor servicing, jam clearing, lockout, confined-space, combustible-dust, vehicle-operation or machinery settings are provided.
