Claim 17:
18. The system according to claim 17, wherein the constraint conditions comprise:
a first constraint condition: Σi∈IfiYi≤P, where fi is a construction cost of the evacuation exit i, Yi is the decision variable, and P is a construction cost threshold;
a second constraint condition: Qi≤MiYi, ∀i∈I, where Qi is the total number of the individuals passing through the evacuation exit i, and Mi is any positive integer greater than Qi;
a third constraint condition: Qi=∫Aiq(x)dx, ∀i∈I, where q(x) is an individual density in the differential area x;
a fourth constraint condition: Yi∈{0,1}, ∀i∈I; and
a fifth constraint condition: Ci(Qi)=1+τcQi, where τc is an evacuation cost coefficient.
