摘要:

We present a combinatorial primal-dual 7-approximation algorithm for the k-level stochastic facility location problem, the stochastic counterpart of the standard k-level facility location problem. This approximation ratio is slightly worse than that of the primal-dual 6- approximation for the standard k-level facility location problem [3] because of the extra stochastic assumption. This new result complements the recent non-combinatorial 3-approximation algorithm for the same problem by Wang et al [21]. © Springer-Verlag Berlin Heidelberg 2010.
