Abstract

A two-stage facility location problem on a tree-like network is considered under the restriction that the transportation costs for a unit of production from one node to another is equal to the sum of the edges in the path connecting these nodes. Some exact algorithm with time complexity O(nm 3) is suggested for this problem, where n is the number of the production demand points and, m is an upper bound on the number of possible facility location sites of each stage.
