The handling cost
What it costs to receive, store, pick and dispatch.
The part
What it is
Handling is labour and space, and it recurs at every node the goods pass through, which is what makes node count expensive.
It is usually held in facility overhead rather than allocated per unit, which is why it stays invisible.
The smallest level
The attributes it carries
Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
