Locating candidate sites for municipal solid waste management facilities is a multi-criteria decision and involves spatial consideration that all municipalities have to deal with. This study aims to develop a holistic model for locating the most suitable facility sites in municipal solid waste management considering environmental and economic factors, and its application to an incineration facility in Izmir as a case study. A fuzzy analytic hierarchy process model was developed by integrating multi-criteria decision analysis methods and a geographic information system. A stepwise methodology was conducted, including generating a spatial database, exclusion analysis, preference analysis to determine spatial membership degrees and weights for each preference factor and generating the final land suitability map. A high-resolution land suitability map and the point vector format data of potential incineration plant sites were created as the model outputs. The case study results demonstrated that an incineration facility with a total capacity of 117 MWe could be established for energy recovery from 5649 tonnes day^–1 municipal solid waste. Four locations were determined as potential incineration facility sites in the case study area. The model can be utilized for different study areas to aid decision-makers in the process of site selection for not only incineration facilities but also for other municipal solid waste management facilities.

确定市政固体废物管理设施的候选地点是一项多标准决策，涉及所有市政当局都必须处理的空间问题。这项研究旨在开发一个整体模型，在考虑环境和经济因素的情况下找到城市固体废物管理中最合适的设施地点，并将其作为案例研究应用于伊兹密尔的焚化设施。通过集成多准则决策分析方法和地理信息系统，建立了模糊层次分析模型。进行了逐步分析，包括生成空间数据库，排除分析，偏好分析，以确定每个偏好因子的空间隶属度和权重，并生成最终的土地适宜性图。创建了高分辨率土地适宜性地图和潜在焚烧厂址的点矢量格式数据作为模型输出。案例研究结果表明，可以建立一个总容量为117 MWe的焚化设施，以从每天5649吨的能量中回收能量^–1城市固体废物。在案例研究区域中，确定了四个位置作为潜在的焚化设施场所。该模型可用于不同的研究领域，以帮助决策者在选址过程中不仅用于焚烧设施，而且还用于其他城市固体废物管理设施。
