AI Technical Summary

Technical Problem

In existing technologies, the cross-process utilization of cold and hot coil scraps has problems such as low work efficiency, easy error, and difficulty in achieving global optimization. In particular, in steel production, the rules for cross-process utilization of cold and hot coil scraps change frequently and the material types are diverse.

Method used

By acquiring multiple futures contracts of the same steel grade and multiple hot and cold coil scraps, a weighted bipartite graph is constructed to form a matching relationship graph. The maximum weight matching algorithm of the bipartite graph is used to solve the matching scheme, determine the matching weight of the matching pair, and realize the automated and large-scale matching of hot and cold coil scraps across processes.

Benefits of technology

It improves the efficiency of using hot and cold coil scraps across processes, achieves optimal utilization of scraps globally, reduces steel companies' inventory, shortens the delivery period of futures contracts, and enhances adaptability and flexibility to dynamic production.
