Evaluating the economic and institutional resilience of urban communities to natural disasters using PROMETHE technique

Nowadays، communities are more focused on rapid recovery and returning to pre-crisis status in the event of a crisis. Therefore special emphasis is being put on the notion of resilience instead of vulnerability. In this applied research، descriptive-analytical methods were used to identify the indicators affecting economic and institutional resiliency and to evaluate these indicators in the city of Tehran. After defining the indicators through library-based studies، their weights were calculated using a questionnaire answered by domestic and foreign specialists and AHP method. In the next stage a field study was carried out to gather the required information from the sample households and neighborhoods. And finally AHP and PROMETHE methods were used to rank the resilience of the sample neighborhoods. Results indicate that economic indicators of ‘Loss rate’ (0. 383) and ‘Compensation capacity’ (0. 281) have the highest weights while ‘Institutional efficiency’ (0. 127) and ‘Ability to recover’ (0. 104) are of medium importance and ‘Institutional context’ (0. 056) and ‘Institutional relations’ (0. 049) are the least significant indicators. Furthermore، based on PROMETHE method، Gheitarieh، Satarkhan، Narmak and Ghale Morghi were ranked as the first four neighborhoods in terms of economic and institutional resilience.
