Over time, the number of unexpected earthy, oceanic and atmospheric events is rising each year. Hence disaster management is considered as one of the most important scientific and practical issues that nowadays developed and developing countries have turned to it. In this study, the preparedness and the response phases of disaster management is modeled using a multi-objective two stage mathematical programming model under uncertainty conditions. In the first stage- the preparedness phase, the location on hospitals, the location and the capacity of shelters and distribution centers and Telecommunication tower are identified before the disaster, predicting the post disaster situations and therefore, the first stage deals with the location problem. In the second stage and the response phase, allocating hospitals to affected areas, affected areas to shelters, affected areas to hospitals, distribution centers to shelters and selecting the best routes for victims evacuation are done that the allocation and routing problem for these measures are deemed necessary. Also in the response phase priority of the demand areas, according to the weight assigned to them, has been considered. This model pursues the following objectives: 1. Minimizing the total demand for each travel. 2. Minimizing distance between affected area and shelters (Routing problem). 3-Minimizing the total transfer cost, Establishment of facilities and the total cost of settling telecommunication towers. In this model, the destruction of facilities, infrastructures due to the disaster and the severity of the disaster are taken into account; so the model uncertainties is in the amount of demand. To solve the proposed model, Non-dominated Sorting Genetic Algorithm (NSGAII) and for prioritize of affected areas TOPSIS Technique for the case study of earthquake in Tehran are used. The results show that the proposed model can be used to decide on the location of hospitals, the location and the capacity of shelters, relief distribution centers and telecommunication towers, allocate resources and determine appropriate routs for evacuated people in a disaster situation and under uncertainty.
