Evaluate Ho Chi Minh City Sustainability Using Fuzzy Extent Analysis Method

Sustainable development of cities was among the goals aimed by either country or region since the 1980s. Ho Chi Minh City was ranked as the most rapid urban development in Vietnam, which challenged the accommodation of the necessities for a pleasant life in a city with limited resources, including housing, public infrastructure, a clean environment, security, safety, employment, and other necessities. The purpose of this study was to measure city sustainability by employing fuzzy decision analysis. A systematic review of the literature has provided the theoretical framework for measuring sustainable cities. Further consent on the criteria of a sustainable city in the context of Ho Chi Minh City, Vietnam was confirmed based on the evaluation of thirty experts with academic and practical experience in the field. The research findings provided the measurement model of city sustainability at three levels with three main criteria at 2nd level and twenty sub-criteria at 3rd level. The research results revealed that there is great consent for city performance and priority ranking in terms of the social dimension. However, great conflict in the importance and performance of economic and environmental dimensions has been found. This practically implied the strategies for bridging the gap between the city’s actual criteria performance and priority ranking in target city sustainability.
