Case Study on the Production Lot Planning of the Hot Rolling Strip

A concrete model for production lot planning of hot rolling strip was constructed based on practical production process and general method of production lot planning of steel rolling plant. By analyzing model parameters, a specific representation of the model parameter was given. The genetic algorithms were successfully applied to production lot planning of the hot rolling strip. An experimental original system has been developed by combining operational research with human-machine cooperation technology. This system has two benefits: (1) improving hot rolling scheduling quality. Hot rolling schedules created by the new system are superior to that produced by the manual system. The average improvement by the new system is over 20% in comparison with old system (manual system); (2) reducing the time taken by creating the hot rolling schedules.
