 Previous research implies that the performance of routing algorithms for evacuation proposes are sensitive to  initial distribution of evacuees, occupancy rate, disaster type as well as disaster location. In other words, a well performed algorithm in one scenario may achieve bad results in another scenario.

 Previous research implies that the performance of routing algorithms for evacuation proposes are sensitive to initial distribution of evacuees, the occupancy levels, the type of disaster and its as well its locations. Thus an algorithm that performs well in one scenario may achieve bad results in another scenario.
