| 摘要: |
| 以延安市区生活垃圾处理方案为研究对象，采用模糊数学模型对3种生活垃圾处理方案(填埋、焚烧 填埋、堆肥 填埋)进行优选。针对延安市区生活垃圾的特点和城市特征以及方案论证必须要考虑的因素，分别从技术、经济、环境、管理、政策等5个层次，选取15个准则作为比选的依据。以选择经济适用的处理方案为目标层，构建层次结构模型。运用三标度法对定性指标进行量化，对可以定量的因素直接进行归一化处理，建立各层次问的判断矩阵，确定各个因素的权重系数向量，并由单因素评价子集建立隶属函数和单因素评价矩阵，最后根据模糊综合评判确定各个备选方案的总评分值，从中选出最优方案。结果表明，焚烧 填埋法是环境可持续、经济可承受及社会可接受的最优方案，其次为填埋法，堆肥 填埋的方案可行性最差。 |

| Optimization of MSW treatment schemes by fuzzifying mathematics in Yan'an city |

| Abstract: |
| Fuzzifying mathematics was adopted for optimization by studying MSW treatment scheme of Yan'an city.The three drifted schemes were landfill,incineration plus landfill and compost plus landfill.The fifteen norms stemmed from technology,economy,environment,management,policy stratums were aimed at characteristics of Yan'an MSW.The economic and suitable schemes were taken as target stratum.The stratified structure model was established.The qualitative norms were quantified by three-scale method.The quantitative factors were handled to be normalization.Judging matrixes of different hierarchies and weight vector of different factors were offered.Membership function and one-factor evaluate matrix were established by one factor evaluate subset.The gross mark of all selected schemes was fixed according to fuzzifying synthetical judge.The results showed that the scheme of incineration plus landfill was the best disposal system.Then landfill,compost plus land fill was the worst scheme. |
