摘要
The single facility location problem with demand regions seeks for a facility locationminimizing the sum of the distances from n demand regions to the facility. The demand regions represent sales markets where the transportation costs are negligible. In this paper, we assume that all demand regions are disks of the same radius, and the distances are measured by a rectilinear norm, e.g. l(1) or l(infinity). We develop an exact combinatorial algorithm running in time O(n log(c) n) for some c dependent only on the space dimension. The algorithm is generalizable to the other polyhedral norms.
