Abstract

利用ELECTRE II法对深圳水库流域2020年的九个污水处理方案进行了优选。从决策准则、候选方案、决策方法及方案排序四个方面做了分析。1) 建立了决策指标体系并确定了指标权重,包括对深圳水库水质的影响、对沙湾河水质的影响、总投资、运行费用、实施难度及事故风险等六个指标;2) 识别了九个候选方案并计算了各方案的指标值;3) 根据研究问题的特点选择ELECTRE II作为决策方法;4) 计算了各方案的排名并进行了敏感性分析,提出方案五(全流域污水集中处理)为最优方案且排名稳定。 The selection of a sewage treatment plan from nine plans for Shenzhen Reservoir Basin is addressed using ELECTRE II method. Four aspects are covered, including criteria, alternatives, aggregation method and ranking. 1) We defined and obtained weights for criteria that take into account water quality of Shenzhen Reservoir and Shawan River, total investment, operating cost, difficulty of implementation, and risk. 2) We identified nine alternatives and evaluated them. 3) The ELECTRE II method was adopted according to the characteristics of the problem. 4) Alternatives were ranked and the results revealed that Alternative Five which centralized sewage treatment is ranked first. The sensitivity analysis reinforced that conclusion.
