What this model is

The whole Bottling Line modeled as one Constraint at 100 bottles/min, with five Interrupts competing on it — this is the line-level rollup. The 5-Constraint model (next card to the right) splits the same line into five per-machine Constraints. Same plant, same answer — close-coupled machines make the line-level rollup and the per-machine view equivalent for throughput.

Questions it answers

  • "Where's the bottleneck?" (spoiler: at the line level there isn't a structural one)
  • "Why is the line at ~53% efficiency?"
  • "How does this compare to the 5-Constraint model?"

The same topology on the other track

One Constraint, LEDS-Level Interrupts runs this structure against LEDS-level interrupt data. It reports 53.2% efficiency against 53.4% here — the throughput prediction barely moves. What changes is what the model can tell you about the cause.
