Application of an Intelligent Integrated Planning and Scheduling System for DHCR

The direct hot charge rolling process can reduce energy consumption, increase production output, and shorted waiting times between production stages, but the integrated planning and scheduling problem for hot charge rolling process was an NP hard. An intelligent integrated planning and scheduling system for direct hot charge rolling process was introduced in this paper. The intelligent system frame and function, especially the integrated planning and scheduling models and the optimization method, have been described in detail. The actual application showed that the solution for integrated planning and scheduling problem of direct hot charge rolling was feasible and effective.
