Theory 198/Elevator scheduling/Ratio lens
Capacity Is Round Trip Against Interval
The claim
System capacity is set by the ratio of round-trip time to the target interval, so a faster car does not increase capacity if the interval is fixed.
01Mechanism
Capacity is cars per interval; the ratio determines how many round trips fit.
02Prediction
Capacity should track the ratio.
03Refutation
Capacity tracking car speed would remove the interval.
