Drum-Buffer-Rope
Flow
Drum-Buffer-Rope
TOC scheduling method: the constraint sets the pace (drum), protected by a buffer, with material release tied to it (rope).
Examples
- 01The CNC bottleneck is scheduled; material is released only as fast as it consumes.
- 02A 4-hour time buffer protects the bottleneck from upstream disruptions.
- 03WIP falls by 35 % after introducing the rope.
