摘要：
We study the fault-tolerant facility location problem with penalties (FTFLPWP). We present an LP-rounding 4-approximation algorithm. Then we apply the randomized rounding technique to improve the approximation to 3.16, which is further improved to 2.408 by the greedy augmentation technique. (C) 2019 Elsevier B.V.
