Decision makers in developing countries are struggling to solve the present problems of solid waste management. Prioritisation and ranking of the most important indicators that influence the waste management system is very useful for any decision maker for the future planning and implementation of a sustainable waste management system. The aim of this study is to evaluate key indicators and their related sub-indicators in a group decision-making environment. In order to gain insight into the subject it was necessary to obtain the qualified opinions of decision makers from different countries who understand the situation in the sector of waste management in developing countries. An assessment is performed by 43 decision makers from both developed and developing countries, and the applied methodology is based on a combined use of the analytic hierarchy process, from the multi-criteria decision-making set of tools, and the preferential voting method known as Borda Count, which belongs to social choice theory. Pairwise comparison of indicators is performed with the analytic hierarchy process, and the ranking of indicators once obtained is assessed with Borda Count. Detailed analysis of the final results showed that the Institutional-Administrative indicator was the most important one, with the maximum weight as derived by both groups of decision makers. The results also showed that the combined use of the analytic hierarchy process and Borda Count contributes to the credibility and objectivity of the decision-making process, allowing its use in more complex waste management group decision-making problems to be recommended.
发展中国家的决策者们正在努力解决当前的固体废物管理问题。对影响废物管理系统的最重要指标进行优先级排序和排名，对任何决策者未来规划和实施可持续废物管理系统都非常有用。本研究的目的是在群体决策环境中评估关键指标及其相关子指标。为了深入了解该主题，有必要获取来自不同国家、了解发展中国家废物管理部门情况的决策者的专业意见。43位来自发达国家和发展中国家的决策者进行了评估，所应用的方法基于多准则决策工具集中的层次分析法（Analytic Hierarchy Process）与属于社会选择理论的名为博尔达计数（Borda Count）的优先投票方法的结合使用。指标的成对比较通过层次分析法进行，一旦获得指标排名，就用博尔达计数法进行评估。对最终结果的详细分析表明，制度 - 行政指标是最重要的指标，两组决策者得出的权重最大。结果还表明，层次分析法和博尔达计数法的结合使用有助于提高决策过程的可信度和客观性，因此建议将其用于更复杂的废物管理群体决策问题。
