| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We study dynamic tree network to represent evacuation of evacuees originally at vertices by using a road network to a safety place called a sink. In dynamic tree $T=(V,E)$, a supply (a number of evacuees) is associated with each vertex $vin V$, each edge $ein E$ is associated with a transit time and a capacity $c$. The capacity limits the maximum number of evacuees that can enter $e$ per unit time We assume $c$ takes the same value for all edges. In addition, one vertex $v$ is designated as a sink $s$ which represents a safety place to which all evacuees evacuate to. The problem is to find an optimal location of a sink that minimized the sum of evacuation time for all evacuees. We propose an $O(n^2)$ time an $O(n^2)$ space algorithm to find an optimal sink location. |
