Example text

6) 38 X. You et al. Definition 5 (Closeness Centrality of Time). Closeness Centrality of Time of a node u (CCTu ) is the sum of the average time needed on SP T (u, v) (spt(u, v)) for v among all the other nodes and the ground transportation time. More formally, spt(u, v) CCTu = v∈V ∧v=u |V | − 1 + tu . (7) Definition 6 (Closeness Centrality of Budget). Closeness Centrality of Time of a node u (CCBu ) is the sum of the average budget needed on SP B(u, v) (spb(u, v)) for v among all the other nodes and the ground transportation budget.

For each integer i in {1, 2}, let Pi be the directed path obtained by removing ai from Li . Then, for every integer i in {1, 2}, we have i (Pi ) = 0. This completes the proof. 2 Integral Supplies and Sink Capacities Here we consider problems of finding an integral allocation of supplies and sink capacities. We consider Integral Mixed Evacuation with Arc Capacities (imeac for short) defined as follows. We are given vectors w1 , w2 ∈ ZA + such that w1 (a) + w2 (a) ≤ c(a) for every arc a in A. Then, the goal is to decide whether there exists a feasible assignment (d1 , d2 , w1 , w2 ) such that d1 , d2 ∈ ZS∪T .

We prepare two scenarios. The first one is that people should have to evacuate to the outside of the inundation area. The second is that people should have to evacuate to the outside of the inundation area or to tsunami evacuation buildings located inside of the inundation area. There exist six evacuation buildings inside the inundation area (numbered from 1 through 6 in the right figure of Fig. , the maximum number of evacuees that can be accommodated) are 1472, 2000, 1128, 3014, 654 and 454, respectively.
