“…If r j − s j > 0, this means that attribute j has a more significant influence on other attributes, which is called a causal factor; conversely, if r j − s j < 0, this means that attribute j is more influenced by other attributes, which is called an affected factor. In this paper, the centroid method is used to defuzzify the fuzzy values (e.g., φ � (φ L , φ M1 , φ M2 , φ U )) to obtain the crisp value (φ) as shown in the following equation [20].…”

“…Next, r j and s j are obtained as r j and s j , respectively, by the defuzzification procedure of (20). e relative coordinate positions of each attribute are clearly plotted using r j + s j as the horizontal axis and r j − s j as the vertical axis.…”

“…When evaluating alternatives based on criteria/attributes/indicators, experts/ decision makers usually refer to extreme values of attributes (the-larger-the-better and the-smaller-the-better characteristics) in many MADM methods, such as COmplex PRoportional ASsessment (COPRAS), Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS), VIseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR), ELimination Et Choice Translating REality (ELECTRE), and Preference Ranking Organization METHod for Enrichment Evaluation (PROMETHEE). In these methods, TOPSIS and VIKOR use the same principles to determine positive and negative ideal solutions based on the extreme values of the attributes [20]. However, in the real world, many attributes do not belong to the-larger-thebetter or the-smaller-the-better characteristics, or there are ranges of preferences for these attributes rather than simply extreme values, e.g., temperature and humidity for human habitation, optimal age for athletes, human blood pressure and heart rate, and height of ideal partners.…”

Natural disasters and man-made incidents have many negative impacts on major cities, including casualties, economic losses, disruption of social order, and environmental contamination. Cities need to be resilient in order to protect people’s lives and property. Although research on urban resilience has been rapidly emerging in recent years, there are still some research gaps. The interplay of attributes for assessing urban resilience has not been explored, and the Multiple Attribute Decision Making- (MADM-) based framework for evaluating urban resilience is rarely studied. Therefore, this study proposes a novel model to evaluate urban resilience, the Z number-based Decision-Making Trial, and Evaluation Laboratory (Z-DEMATEL), to identify the mutual influential relationships and the weights of the attributes. In addition, the Z number-based Reference Ideal Method (Z-RIM) is used to determine the resilience capacity of cities and to suggest improvements for decision makers to develop appropriate strategies. In this study, we not only use trapezoidal fuzzy numbers to reflect the uncertainty of information but also measure the reliability/confidence of experts in the assessment. The integrated methodology is presented for the first time in this study, and we use the firmness data of six major metropolitan cities in Taiwan as an example of model demonstration. The results of the study show that population density, value of business activity, healthcare facilities, electricity supply, and number of business registrations are the most important attributes influencing the resilience of cities. Taipei City and Taichung City are the two major cities with better resilience in Taiwan based on the analysis of this study.
