Maritime　transportation　has　kept　a　steadily　fast　development　in　recent　decades,　which　puts　higher　requirement　to　the　port　operation.　Lots　of　works　addressed　the　integrated　scheduling　of　berth　and　quay　crane,　however,　most　of　them　ignore　the　impact　of　maintenance　activities,　especially,　the　uncertain　quay　crane　maintenance.　In　this　paper,　we　investigate　an　integrated　berth　allocation　and　quay　crane　assignment　with　uncertain　quay　crane　maintenance　activities,　and　establish　a　stochastic　integer　linear　programming　model　to　minimize　the　excepted　total　turnaround　time　of　vessels.　A　sample　average　approximation　method　is　applied　to　solve　the　problem.　Numerical　experiments　with　90　instances　are　conducted,　which　verify　the　accuracy　and　efficiency　of　the　proposed　model　and　method.
