摘　　要：系统地研究了在约束条件可调整的情况下CMMO问题中可行性与目标协调的关系,论述了当系统优化不可行时,在进行软约束调整的过程中要兼顾系统的期望目标,以获得满意的优化结果.运用混合逻辑的方法描述了软约束调整的优先级,并将多目标协调问题转化为逻辑约束满足问题,从而系统地解决了稳态优化中软约束调整与目标协调问题.以壳牌重油分馏塔标准问题为例进行了仿真,仿真结果表明了该算法的有效性.The relationship between feasibility and objectives coordination of CMMO problem under flexible constraint conditions is discussed. That soft constraints adjustment and objective relaxation are required to get satisfying result when the optimization problem is infeasible. The mixed logic method is introduced to describe the priority of the constraints and objectives, thereby the soft constraints adjustment and objectives coordination are solved systemically in real-time dynamic optimization. Simulation is processed with the example of the shell heavy oil fractionators benchmark problem, and the result shows the validity of the algorithm.
