Abstract: Referring to Drum-Buffer-Rope (DBR) theory, a novel scheduling strategy with the core of bottleneck equipment control was designed for a kind of complex manufacturing system with multi-reentrant flows. For bottleneck identification, the concept of layered bottleneck was presented, and the calculation methods of system bottleneck and sub-layer bottlenecks were discussed. Based on layered bottleneck thoughtway, the Different Layers Scheduling (DLS) algorithm and its implementation procedures for multi-reentrant manufacturing systems were further explored. Finally, HP-24 semiconductor production line was used as an example to demonstrate the effectiveness of the proposed methods.

Key words: layered bottleneck, multi-reentrant manufacturing, scheduling algorithm, drum-buffer-rope theory
