What this model is

The same line as the 1-Constraint model, split into five per-machine Constraints (Filler → Capper → Labeler → Case Packer → Palletizer) with one Interrupt each — machine-level detail kept. The throughput answer lines up with the 1-Constraint rollup (both land at ~54% OEE and ~7M bottles): that's the point — close-coupled Constraints roll up cleanly into the line-level view. The difference shows up in 36% blocked-or-starved time — stages waiting on each other, which the 1-Constraint rollup can't show because there's only one node.

The line

Node Type Detail
Bulk Storage Buffer ∞ supply
Filler Constraint 100/min · 1 interrupt
Capper Constraint 100/min · 1 interrupt
Labeler Constraint 100/min · 1 interrupt
Case Packer Constraint 100/min · 1 interrupt
Palletizer Constraint 100/min · 1 interrupt
Warehouse Buffer ∞ capacity

Five serial Constraints · one interrupt each · OEE 54.7% · bottleneck: Case Packer · 7.09M bottles · 36% blocked-or-starved

The same topology on the other track

Five Constraints in Series — LEDS Interrupts runs this structure against LEDS-level interrupt data. It reports 54.0% efficiency against 54.7% here — the throughput prediction barely moves. What changes is what the model can tell you about the cause.
