层次分析法在四川省城市生活垃圾处理技术方案选择中的应用

摘要

The disposal method of municipal solid waste（MSW） in Sichuan Province was studied by analytic hierarchy process（AHP）.Firstly,the hierarchy was built and then the objective items were compared to each other to work out the weight of decision layer to objective layer.As an example,Chengdu was analyzed by AHP which showed that incineration was the best method of MSW disposal in this city.Lastly,a simplified method of AHP worked on MSW disposal method selection in Sichuan was given,and provided referencl for municipal solid waste disposal method.%以四川省城市生活垃圾处理技术方案为研究对象,使用层次分析法构建层次结构,进行目标项两两比较确定权重及归一化处理,确定决策层对目标层的权重。并以成都为实例,确定方案层对决策层的权重,根据权重累加后的综合得分对技术方案进行优选,结果表明成都市采取全部焚烧,并对焚烧余热进行利用是最佳方案。最后对四川省城市生活垃圾处理技术方案选择的层次分析法提出了一种简化方法,为我国城市生活垃圾处理技术方案的选择提供参考。
