将基于目标希望水平的含整变量多目标交互式优化方法用于研究大规模含整量多目标优化问题．针对具有块角约束结构的大规模含整变量优化问题，运用拉格朗日分解技巧，提出了一种比较实用的大规模含整变量多目标交互式分解协调优化方法 The method of multi-objective interactive optimization with integer variables based on the desired level of target is applied to the research of large-scale multi-objective optimization problems with integers. Aiming at the problem of large-scale integral variable optimization with block-angle constraints, a more practical method of large-scale multi-objective interactive decomposition and coordination optimization with integer variables is proposed by using Lagrange decomposition technique
