Abstract：
A tool to quantify the pollution potential of leachate, termed the revised leachate pollution index (r-LPI), has been developed. It was developed using the fuzzy Delphi analytic hierarchy process (FDAHP). The formulation entails four major steps: parameter selection, weight calculation, normalization of parameters, and aggregation of the parameters. Eleven leachate parameters categorized into three criteria were selected using the fuzzy Delphi method (FDM). The relative weights of the parameters and the criteria were computed using the fuzzy analytic hierarchy process (FAHP), and rating curves were used for normalization of the parameters. The selection of an aggregation function is one of the most critical steps in the development of a composite indicator. In this study, the concept of r-LPI was briefly discussed and 14 different aggregation functions were examined to estimate the pollution potential of landfill leachate. Based on accountability and non-accountability of weights of the parameters, ambiguity, eclipsing, and constant functional behavior, 8 aggregation functions were eliminated. The remaining six aggregation functions were subjected to sensitivity analysis. Furthermore, information lost due to aggregation of parameters was quantified. Based on the findings, it was concluded that the weighted additive function effectively quantifies the pollution potential of landfill leachate and thus recommended for the r-LPI.
摘要：
一种量化渗滤液污染潜力的工具，称为修订后的渗滤液污染指数(r-LPI)，已经开发了。它是使用模糊德尔菲层次分析法(FDAHP)开发的。制定需要四个主要步骤：参数选择，重量计算,参数的归一化，和参数的聚合。使用模糊德尔菲法（FDM）选择了分为三个标准的11个渗滤液参数。使用模糊层次分析法（FAHP）计算参数和标准的相对权重，和评级曲线用于参数的归一化。选择汇总函数是制定综合指标的最关键步骤之一。在这项研究中,简要讨论了r-LPI的概念，并检查了14种不同的聚集函数，以估计垃圾渗滤液的污染潜力。根据参数权重的责任和不责任，模棱两可,日食，和恒定的功能行为，消除了8个聚集函数。对其余六个聚集函数进行敏感性分析。此外，量化了由于参数汇总而丢失的信息。根据调查结果,结论是，加权加性函数有效地量化了垃圾渗滤液的污染潜力，因此推荐用于r-LPI。
