Abstract

Optimal financial resource allocation to the seismic Retrofitting of the Infrastructures and specifying their priority are considered as prominent issues in the macro scale decision making process. As the optimum strategy is adopted and the budget allocation is performed with the appropriate priority, it is expected that a significant loss reduction is achieved. When the financial resources are limited, allocating based on the proper priority seems to be more vital. Urban development has been rapidly progressing in Tehran without the development of proper disaster prevention systems against potential Earthquakes. It is urgently necessary to prepare a regional/urban Earthquake disaster prevention plan in order to mitigate possible seismic damages in Tehran. The purpose of the study was to understand how the failure of one Infrastructure or any of its elements propagates to other Infrastructures in order to implement management policies that can mitigate the consequences. In this work, Tehran is initially introduced in aspects of its active faults zone around the city, and its probable Earthquake scenarios. In this work, the optimum strategy for Retrofitting the Infrastructure networks as the water, transportation, communication, gas, and power Infrastructures is investigated using Uncertainty Dynamic Inoperability Input-Output Model (U-DIIM). This optimum strategy is adopted against the Earthquake impacts in terms of the indirect economic losses, sensitivity to the parameters of the commodity flow matrix and cost of Retrofitting strategy. According to the current situations of Infrastructures in Tehran, the inoperability of the lifelines, were gathered from the lifeline documents with the help of Tehran Disaster Mitigation and Management Organization-Tehran Municipality, based on the North Tehran fault Earthquake scenario. Strategy 1, referred as the “ Do Noth g” strategy th s work wh ch dicates the current situation of lifelines in Tehran Province. In summary, strategies are based on different levels of the reinforcement of the structures and hardening strategies for Infrastructures. The cost of implementation, recovery time, and perturbation after Earthquakes calculated for each strategy. By minimizing the total economic loss, sensitivity to economic loss parameters and cost of implementation of strategies, the best scenario is selected for the recovery strategy. Therefore, the indices employed in this research include reducing the economic losses and also the sensitivity with respect to the costs associated with the conduction of the strategy. The Pareto method is also used in this work to select the optimal Retrofitting strategy. The results reveal that increasing the seismic performance of the Infrastructures by 25% is the optimum Retrofitting strategy from the economic point of view. Following this strategy, the ratio of economic loss reduction to the strategy implementation costs and also the ratio of the sensitivity reduction to the strategy implementation costs are 0. 3996 and 3. 66, respectively. It is worthwhile to note that all economic interactions between the Infrastructures are taken into account in the research.
