Layouts by volume

Decision 25: Plus One's layout follows volume. These are the three layouts the N+1 factory engine laid out from demand, copied from nplus1labs/factory at 9bc6753 (engine/examples/plus-one-*-run/layout.json). Each one runs the same eight steps (S1 to S8) and the same target times from this OPD.

Everything here is simulated from assumed values and uncalibrated. No unit has been built.

Layout	File	For	Takt	People	Capacity, good units an hour	Bottleneck
Bench cell	bench-cell.json	the first 100 builder units, in five build days	1,215 s	1	about 17	the technician
U cell	u-cell.json	about 2,000 to 4,500 a month	255 s	2	about 32	the operator on S1 to S6
Balanced MadeCell line	madecell-balanced.json	about 10,000 a month	51 s	7	about 89	W1 (S1 and S2)

• Takt comes from the assumed demand: one 8-hour shift less half an hour of breaks, a 10% allowance and 21 working days a month.
• Capacity comes from a discrete-event run of 2,000 units, with a ±30% spread on every target time.
• The balanced line sits on decision 24's MadeCell base: a 40 x 8 ft frame with four bays and stations facing out from a central conveyor. S8 becomes a cell of three test fixtures.
• Outside the simulation: the audio loopback, the RF check and wireless charging.
