Evaluation and ranking of urban sustainability based on sustainability assessment by fuzzy evaluation model

Abstract

Urban sustainability can be considered as a part of sustainable development, which emphasizes the balance between three dimensions of environmental, economic, and social sustainability to improve human well-being and the quality of life. In this study, it was attempted to assess urban sustainability in the most critical, populous, and expanded district of Tehran (district 4) using sustainability assessment by fuzzy evaluation. For this purpose, 52 primary indices which were divided into 8 secondary components were employed. Among them, 18 indices for environmental issues were grouped into three secondary indices as E1, to E3, and 34 indices for economic-social and cultural issues were classified into five secondary indices as H1 to H5. The results revealed that 56% of the study area was potentially unsustainable and 44% of it had a medium sustainability in terms of environmental aspects. Furthermore, 65% of the study area had a medium human wellbeing sustainability and 35% of it was potentially unsustainable in terms of economic-social and cultural aspects. Finally, 45% of the study area was found unsuitable in terms of overall urban sustainability. The functional sample proposed in the present study can provide the directors and planners with the required information about the condition of sustainability in the most important district of Tehran.

The Resilience Performance Index, a Fuzzy Logic Approach to Assess Urban Resilience

“…Fuzzy Logic Systems are artificial intelligence (AI) tools that have two major advantages; modelling the vagueness and ambiguity inherent in linguistic information, and modelling the fuzziness of spatial data through defining fuzzy sets or categories where one value could simultaneously fit in. Therefore, FLSs can model imprecise quantitative or qualitative data inputs without the need for detailed descriptive mathematical formulae, normalization techniques, and complex aggregation methods [35].…”

“…There are many types of FRB methods such as Mamdani's method, Suengo method, or Takagi-Suengo-Kang method. The most widely applied method is the Mamdani method [53], since it is a simple, easily interpreted method which depends on human reasoning in the form of simple if-then rules, where "If" stands for the "Predicate" whereas "Then" represents the "Conclusion" [35]…”

Applying the Sustainability Barometer Approach to Assess Urban Sustainability

“…The steps of the research process are illustrated in Figure 2. Sustainability indicators are the tools that measure the conditions of an urban area by means of a variety of factors [36]. Knowing that indicators are powerful tools for assessing the progress toward sustainable development, in the current research, indicators were selected by studying relevant studies trusted by experts and prominent international centers, such as Mercer, Arcadis, UN, World Health, World Bank, Organization for Economic Co-operation and Development (OECD), and the International Union for Conservation of Nature (IUCN) [27,[37][38][39][40][41][42].…”
