层次分析法在垃圾卫生填埋场选址中的应用

Application of Analytic Hierarchy Process to Site Selection of Solid Waste Sanitary Landfill

鉴于层次分析法在多目标决策分析方面的成效,将其运用到城市垃圾卫生填埋场场址选择环节。通过对具体候选场址分别进行分析,计算出各场址的相应综合适应性评价得分,比较各候选场址得分,得出最佳场址。整个分析过程和最终结果表明:层次分析法简化了选址过程,操作易于在计算机上实现,改进了传统选址方式定性分析过多,选址结果在很大程度上受主观因素影响的缺点,增强了选址的科学性和合理性。

Since the analytic hierarchy process(AHP) has greatly succeeded in multi-object decision, this paper applies it to site selection of solid waster sanitary landfill. The most feasible site can be decided through calculating and comparing the scores of each site, which are got by AHP. The analytic process and results indicate that the applying AHP in the tache makes the operation concise, and it is easy to carry out with computer. The shortages of traditionary mode of site selection such as overfull qualitative analysis and subjective factors can be improved through application of AHP in great extent, thus it can make this tache more scientific and reasonable.
