摘要：排污负荷分配到源是进行大气污染总量控制的一个基本原则。应用数学规划的方法进行排污负荷分配研究,可以得到区域总体优化的分配方案。通常的线性规划模型在进行该项研究时,存在规划排污量“极端化”的现象,即绝大多数的污染源要么以下界排放,要么以上界排放。这常常不能很好地符合实际工作的需要,引入硬边界约束和软边界约束,很好地解决了这个问题,使得排污负荷分配方案既不失总体优化特征,又能更好地符合实际。

Abstract：By using the methods of mathematical programming,a comprehensively optimal scheme of the allocation for pollutant load discharged was established. The traditional linear programming model often results in an extreme allocation of the pollutant amount discharged from the source,i. e.,the optimal amount of pollutant discharged from each source is either the upper limit or the lower limit for most of the sources. This result can not meet the requirement of the practical applications. By using the solid boundary constraints and the flexible boundary constraints,the problem can be solved. The scheme obtained from the advanced model has the same optimal characteristics as that in the original one.
