HOPS - Hamming-Oriented Partition Search for production planning in the spinnin...

In this paper, we investigate a two-stage lot-sizing and scheduling problem in a spinning industry.A new hybrid method called HOPS (Hamming-Oriented Partition Search), which is a branch-and-bound based procedure that incorporates a fix-and-optimize improvement method is proposedto solve the problem. An innovative partition choice for the fix-and-optimize is developed. The computational tests with generated inst...
