河流允许排污量公平分配的多准则决策方法

针对允许排污量分配领域存在多种公平分配观点与准则的特点,提出了综合考虑所有排污者的公平准则,再对不同准则下的方案进行协调,以期获得全体排污者愿意接受的分配结果.设计了2种求取公平协调解的多准则决策方法,分别采用满意度和公平偏离度作为衡量指标,根据最大化最小值原理求取最佳协调解,求解过程不需要人为给定权重.以广州-佛山跨界河网为例,研究表明,2种方法具有良好的一致性,分配结果较公平合理,可为解决跨界水污染矛盾和实施总量控制制度提供定量化的决策依据.

Multi-criterion decision making methods of river waste load allocation based on principle of equity

Equity of waste load allocation is a multifaceted concept. A polluter trends to choose different allocation rule which may result in favorable alternative while this may not be preferable to the others. It is suggested all measures of equity for which there are backers should be used in the decision making procedure of waste load allocation, and then to form a compromise scheme that all polluters prefer to accept. Two multi-criterion decision making (MCDM) methods are proposed for this purpose, which use Satisfactory Degree and Equity Distance as equity indicators, respectively. A compromise solution is determined according to the principle of maximizing the minimum value. Avoiding giving weights to the polluters, the solution is of objectivity. A case study of waste load allocation is conducted for Guangzhou City-Foshan City trans-boundary river network in Guangdong, China. The results show that the two MCDM methods have similar solutions which are equitable and reasonable. MCDM methods could provide quantitative guidance to solve trans-boundary pollution conflict and implement the policy of Total Pollutant Amount Control for water quality management.
