Identification and Prioritization of Strategies Preventing Disasters Caused By Earthquake in Tehran by Using Hierarchical Fuzzy Method

Efficient disaster management resulting from natural disasters such as earthquake is one of the most challenging subjects of city management especially in the metropolis such as Tehran. In this regard, determination and the implementation of effective prevention strategies or reduce the consequence and damages caused by the earthquake in Tehran is considered as a requirement. But before implementation of any preventive strategy, evaluating their effectiveness on the basis of specified and appropriated criteria was necessary and limitations of time and existing resources for prioritization of these strategies will be also inevitable. By conscious of the importance of such work, in this research reviewing the literature of disaster management and interview with seven experts of disaster management in Tehran, extract the effective prevention strategies and consequences of possible earthquake in Tehran and with definition of appropriate standards, evaluate their effectiveness by decision-making techniques of fuzzy analytical hierarchy process (FAHP). For this, we used linguistic variables for comparison of strategies importance and weight of criteria in the form of paired comparison matrix and then we turn them into a fuzzy paired comparison matrix. Then by using the Chang decision-making technique of FAHP extract conclusive decision making matrix from a fuzzy group of paired comparison matrix. At the end, we prioritize strategies based on specified criteria and strategies with high priority are introduced for prevention and control of consequences of possible earthquake in Tehran.
