Abstract

Landfill site selection is a multi-criteria decision problem and has strategic value for various countries. The conventional method for landfill site selection is not enough to address the vague nature of linguistic assessment. An integrated Fuzzy AHP method was used to resolve this issue. Suitability maps produced by conventional Analytical Hierarchy Process (AHP) and integrated Fuzzy AHP methods were compared and validated, which adds a new dimension in the waste management field. Various environmental, socio-economic, and infrastructure factors were used as predictors, which included groundwater level, soil type, slope, land cover, distance to settlements, railways, roads, surface water sources, airport, power lines, wells, and protected areas. Relative Operation Characteristic (ROC) analyses gave results of 0.77 and 0.86 for the suitability maps of AHP and Fuzzy AHP, respectively. The landfill site suitability maps produced from this study could help urban planners, engineers, decision-makers, and land-use developers to make suitable decisions. Furthermore, the resulted integrated model showed the best suitability that could be implemented to resolve the fundamental landfill siting problems in other cities of Pakistan.

Ahp法与模糊Ahp法评价垃圾填埋场适宜性的比较

垃圾填埋场选址是一个多标准决策问题，对各国都具有战略价值。传统的垃圾填埋场选址方法不足以解决语言评估的模糊性。采用模糊层次分析法解决了这一问题。对传统层次分析法（AHP）和综合模糊AHP法生成的适宜性图进行了比较和验证，为废物管理领域增加了一个新的维度。各种环境、社会经济和基础设施因素被用作预测因素，包括地下水位、土壤类型、坡度、土地覆盖、与定居点、铁路、道路、地表水源、机场、电线、水井和保护区的距离。AHP和模糊AHP的适用性图的相对操作特征（ROC）分析结果分别为0.77和0.86。这项研究产生的垃圾填埋场适宜性地图可以帮助城市规划者、工程师、决策者和土地利用开发商做出适当的决定。此外，所得到的综合模型显示出最佳的适用性，可用于解决巴基斯坦其他城市的基本垃圾填埋场选址问题。
