基于多目标决策的水污染负荷分配方法

为科学、合理地配置汇流区域的水污染负荷,从经济最优性、公平性综合决策角度,构建了一个以区域环境经济收益最大化、水污染负荷削减费用和加权综合基尼系数等最小化为目标的水污染负荷分配多目标决策优化模型,并将该模型应用于巢湖流域COD削减负荷分摊中.计算得到合肥市、肥东县、肥西县、巢湖市、庐江县、无为县、含山县、和县和舒城县等...

Model for wastewater load allocation based on multi-objective decision making

To scientifically and rationally allocate waste loads in a basin, a multi-objective decision making model, which takes such three factors as economic income maximum, pollution abatement cost minimum and weighted comprehensive Gini coefficient minimum to be sub-objective functions, was proposed from the viewpoints of synthetically considering both economy optimization and fair principles. As a case, the model proposed above was applied for the allocation of COD loads among nine cities and counties in Chaohu Lake Basin. Study results indicated that the established multi-objective decision making model was suitable and effective for waste load allocations. Thus, a novel process was provided for the optimization assignment of waste loads.
