An Overview to Indicators and Fuzzy Methods in Determining City Sustainability

Abstract

As a result of the increase in human population, activities implemented to ensure sustainability have increased. Due to the substantial amount of energy and water consumption, and greenhouse gas emissions, cities are regarded as one of the most crucial components of sustainability. In this regard, measuring and assessing the sustainability of cities is crucial. In this study, a systematic literature review was conducted for city sustainability. The initial objective of the research is to identify the dimensions and indicators of city sustainability that are discussed in the literature. For this purpose, a reference study was made, and these factors are identified. The second aim of the study is to reveal the fuzzy-based methods used when calculating city sustainability. This study can contribute to shed light on the current state of city sustainability papers and serve as a reference for studies of this field in the future.
