A new solution for large-scale scheduling in the steelmaking industry, called Finishing Line Scheduling (FLS), is described. FLS in a major steel mill is a task to create production campaigns (specific production runs) for steel coils on four continuous processes for a one-month horizon. Two process flows are involved in FLS, and the balancing of the two(More)

This report is an e ort to consolidate two di erent avors of a surplus inventory matching problem encountered in the steel industry: Surplus Un nished Inventory Matching, and Surplus Finished Inventory Matching. This report is compiled from two other reports that describe the heuristic solution approaches developed for a real world application of these(More)
This paper describes a constrained bin-packing •problem (CBPP) and an approximate, anytime algor i thm for solutions. A CBPP is a constrained version of the bin-packing problem, in which a set of items allocated to a bin are ordered in a way to satisfy constraints defined on them and achieve near-optimality. The algor i thm for CBPP uses a heuristic search(More)
Traditionally, Markov models have not been successfully used for compression of signal data other than binary image data. Due to the fact that exact substring matches in non-binary signal data are rare, using full resolution conditioning information generally tends to make Markov models learn slowly, yielding poor compression. However, as is shown in this(More)
