Site selection is an important issue in waste management. Selection of the appropriate solid waste site requires consideration of multiple alternative solutions and evaluation criteria because of system complexity. Evaluation procedures involve several objectives, and it is often necessary to compromise among possibly conflicting tangible and intangible factors. For these reasons, multiple criteria decision-making (MCDM) has been found to be a useful approach to solve this kind of problem. Different MCDM models have been applied to solve this problem. But most of them are basically mathematical and ignore qualitative and often subjective considerations. It is easier for a decision-maker to describe a value for an alternative by using linguistic terms. In the fuzzy-based method, the rating of each alternative is described using linguistic terms, which can also be expressed as triangular fuzzy numbers. Furthermore, there have not been any studies focused on the site selection in waste management using both fuzzy TOPSIS (technique for order preference by similarity to ideal solution) and AHP (analytical hierarchy process) techniques. In this paper, a fuzzy TOPSIS based methodology is applied to solve the solid waste transshipment site selection problem in Istanbul, Turkey. The criteria weights are calculated by using the AHP.
选址是废物管理中的一个重要问题。由于系统的复杂性，选择合适的固体废物处理场地需要考虑多种替代方案和评估标准。评估程序涉及多个目标，而且通常有必要在可能相互冲突的有形和无形因素之间进行权衡。基于这些原因，多准则决策（MCDM）已被证明是解决这类问题的一种有用方法。不同的MCDM模型已被应用于解决这个问题。但它们大多基本上是数学模型，忽略了定性的、往往是主观的因素。决策者用语言术语来描述一个替代方案的值会更容易。在基于模糊的方法中，每个替代方案的评级用语言术语来描述，这些术语也可以表示为三角模糊数。此外，还没有任何研究同时使用模糊TOPSIS（逼近理想解排序法）和AHP（层次分析法）技术来关注废物管理中的选址问题。本文应用基于模糊TOPSIS的方法来解决土耳其伊斯坦布尔的固体废物转运站选址问题。准则权重通过层次分析法计算得出。
