In　this　paper,　we　study　a　stochastic　version　of　the　fault-tolerant　facility　location　problem.　By　exploiting　the　stochastic　structure,　we　propose　a　5-approximation　algorithm　which　uses　the　LP-rounding　technique　based　on　the　revised　optimal　solution　to　the　linear　programming　relaxation　of　the　stochastic　fault-tolerant　facility　location　problem.　©　2013　Operations　Research　Society　of　China,　Periodicals　Agency　of　Shanghai　University,　and　Springer-Verlag　Berlin　Heidelberg.
