Abstract: This disclosure relates to the field of metallurgical automation technologies, and discloses a method and device for cross-process use of cold/hot-rolled excess material, medium, and program product. The method is applied in an electronic device. In this method, multiple futures contracts and multiple cold/hot-rolled excess materials with same steel grade are obtained, forming at least one matching pair consisting of a futures contract and a cold/hot-rolled excess material by taking the multiple futures contracts and the multiple cold/hot-rolled excess materials as nodes in a weighted binary graph, to construct a matching relationship graph. In addition, a matching weight of each matching pair in the at least one matching pair is determined. Then, a use solution is obtained by computing the matching relationship graph based on a binary graph maximum weight matching algorithm. By doing so, the automation and scale of cross-process use of cold/hot-rolled excess materials can be implemented, the use efficiency of cold/hot-rolled excess materials and futures contract can be improved, and the optimal use of excess materials can be achieved.
