We consider the k-level stochastic facility location problem. For this, we present an LP rounding algorithm that is 3-approximate. This result is achieved by a novel integer linear programming formulation that exploits the stochastic structure.

The star-star concentrator location problem (SSCLP), which is a network layout problem, is considered. SSCLP is formulated as an integer linear programming problem. The Lagrangian relaxation (LR) method is used to obtain suboptimal solutions (upper bounds) and lower bounds. Three different LRs are u
