Abstract In the procedure of steadystate objective calculation, the soft constraints adjustment and objective relaxation were required for getting satisfying results when the optimization problem is infeasible. The goal priority factor was introduced to describe the priority of the constraints and objectives; thereby the soft constraints adjustment and objectives coordination were solved systemically in realtime steadystate objective calculation. Simulation was processed with the example of the shell heavy oil fractionators benchmark problem, and the result shows the validity of the proposed algorithm.
