Abstract：Existing cloud manufacturing service compositionmethods aretypicallydevelopedunder theassumption of no anomalies inmanufacturingservices，which renderscurrent modelsandmethods ieffcientoreven prone tofailurewhenservice anomalies occur.Toaddressthis issue，this paper proposedarobust servicecomposition methodforcloud manufacturing basedonanimprovedmulti-objective whaleoptimizationalgorithm.Firstly，the methodefectivelyavoided isues suchasinefficiencyortask failurecausedbyanomalies inpreferedservicesbyasigningapreferredservice andanalternative service to eachsubtask．Next，the methodusedtask latency timeasarobustness indicatorforcloud manufacturing servicesandconstructedamulti-objectivecloud manufacturingservicecompositionmodelthatconsideredbothrobustnessandqualityofservicerequirements.Tosolvethis model，themethoddesignedanimprovedmulti-objective whaleoptimizationalgorithmbasedonahybridstrategy.Finally，analysisofdifferentarithmeticcasesshowsthattheproposed methodoutperformsothergoodmethodsof convergence and diversity.
