Abstract
Humanitarian aid is one of the most popular and important subjects nowadays. This is because, in some disasters like Corona
epidemy in Wuhan, China, the regional aid is not sufficient to compensate the damages and to protect the people. Therefore,
the management and distribution of these humanitarian aids is of paramount importance. In this manuscript, first, we model
the need of first aids in the city by considering the current situation e.g. total population, number of sick people, dead people,
number of needed hospital staff and so forth. Then, this model is solved in two phases: (1) in first phase, we ignore the cost
criteria and we use airplanes to provide the required materials to maximize the speed. (2) in the second, we consider the tradeoff between cost and speed criteria which introduces the train as the optimal solution.
