针对一类混合(连续/离散)流水作业模型预测控制问题，提出了一种新的建模方案。在传送带类型的流水作业中，插入机器的作业的排列调度和机器内作业的连续动态控制同时优化。这种建模可以减少混合整数规划(MIP)问题中的二元决策变量的数量，从而显著减少求解该问题的计算负担。将该方法应用于某热连轧板坯加热炉的控制。
This paper proposes a novel modeling scheme for model predictive control of a class of hybrid (continuous/discrete) flowshops, where permutation scheduling of jobs inserted into machines and control of continuous dynamics on jobs inside machines are simultaneously optimized in the conveyor-type flowshops. This modeling allows us to reduce the number of the binary decision variables in the resulting mixed integer programming (MIP) problem, thereby achieving a remarkable decrease in the computational burden of solving it. The proposed method is applied to slab reheating furnace control for a hot strip mill.
