| Output unit | pallets |
What this model is
This model introduces Converters: the Filler, Case Packer (10 bottles → 1 case), and Palletizer (10 cases → 1 pallet). Only two nodes are real Constraints now (Capper and Labeler); the others are Converters doing bundling math. Output is measured in pallets. Bottleneck: the Filler Converter, system OEE 54.1%.
The line
| Node | Type | Detail |
|---|---|---|
| Bulk Storage | Buffer | ∞ supply |
| Filler | Converter | 100/min |
| Capper | Constraint | 100/min · 1 interrupt |
| Labeler | Constraint | 100/min · 1 interrupt |
| Case Packer | Converter | 10/min · 10:1 |
| Palletizer | Converter | 1/min · 10:1 |
| Warehouse | Buffer | ∞ capacity |
2 Constraints + 3 Converters · bottles → cases (10:1) → pallets (10:1) · OEE 54.1% · bottleneck: Filler (n0) · output in pallets

The same topology on the other track
Two Constraints, Three Converters — LEDS runs this structure against LEDS-level interrupt data. It reports 54.3% efficiency against 54.1% here — the throughput prediction barely moves. What changes is what the model can tell you about the cause.
