Natural disasters such as earthquakes, floods and so on have always been existed and evey year, millions of people in all over the world affected from these events. Hence, using optimization tools to improve disaster management operation is one of the most important issues that nowadays have been attended by many researchers.
Therefore, disaster relief logistic planning, which is one of the critical asopects of disaster management, is considered in this study. To achieve this purpose, a relief chain included shelters, relief distribution centers, and affected areas has been designed, which is inspired from real condition of earthquake in Seattle. In order to identify the identify the quantity of damages and victims in affected areas, seismic damage assessment and vulnerability map of the urban area have been used.
This model is capable to define an outlook of pre-disaster decisions. The prepration phase considers location of relief distribution centers and the distribution planning of relief commodities in these centers under different earthquake senarios in the urban area.
The mathematical model has two objectives include minimizing the total costs of operation. The second objective aims to maximize the utility level of each shelter by taking into account the time utility and shelters’ priority. Finally, to solve these models, an augmented ε constraint method is used and computational results have been analyzed.
