Abstract
In this paper, we study the uncapacitated facility location problem with service installation costs depending on the type of service required. We propose a polynomial-time approximation algorithm with approximation ratio 1.8081.808 which improves the previous approximation ratio of 2.3912.391 of Shmoys, Swamy, and Levi.
