Abstract：Operation experiences of operators affect the enterprise economic benefit and production safety in the pro-duction process.Motivated by improving efficiency and safety,a real-time online decision support system with priority is proposed in this paper,combining with the idea of steady-state target calculation(SSTC)in two-layer model predictive con-trol(MPC).For the case that cost coefficient can not be determined accurately,the operation priority optimization method is introduced.the optimal operation target(including controlled variables and manipulated variables)is calculated based on the priority idea of controlled variables of SSTC layer.The problem that the importance of independent variables can't be distinguished for each layer modules in modular multivariable operation guidance is solved,and the similarity of structure between multi-priority optimization and modular multivariable optimization is explained.Finally,an example of decision support system based on the proposed method is taken and the effectiveness of the methods mentioned is proved.
