Production planning system in clothing enterprises based on Drum-Buffer-Rope theory

To solve the problem with low Due Date Performance (DDP) and throughput in clothing enterprises, we propose a new bottleneck scheduling algorithm, design and implement production planning system with a core of the algorithm based on Drum-Buffer-Rope (DBR) theory. Firstly, Shipping Buffer model is built for typical clothing enterprises; secondly, some problems of traditional scheduling for the bottleneck are discussed, and an Insertion neighborhood search algorithm and an example to minimize TDD are presented; thirdly, material releasing is created and the mechanism of three colored zone Buffer Management is introduced; finally, the system with the algorithm has successfully been implemented in one of the famous brand clothing enterprises and achieves good results, which bring high DDP and throughput to the enterprise. The enterprise economic efficiency also has improved.
