Charge Planning in Steelmaking Industry
|||
Iron and steel are used widely in the world. The key processes for steelmaking including the basic oxygen steelmaking, the continuous casting and the hot rolling. As these processes are coupled to each other, integrated batch planning for each process is important for guaranteeing competitive steelmaking plant performance. we focus on one main batch planning for the processes of basic oxygen steelmaking, which are Integrated Charge Planning (ICP).
ICP, for the given technical constraints (hard and soft constrains), deals with determining which slabs are assigned into one charge to minimize charge number; and maximum the sum of slab weight in all charges. As the problem is NP-hard, two new heuristics based on a variable neighborhood search (VNS) are designed, one is harmony search embedded guided VNS, and the other is simulation annealing embedded guided VNS. We highlight the summary of solutions obtained by each of them for comparisons of these algorithms.The data of the ICP are attached.
