Title:IntegrationofSingle-StepandMulti-StepOptimizationStrategiesinDiagnosticProcess
Introduction:
Diagnosingfaultsandoptimizingsystemperformanceisofutmostimportanceinvariousindustries,suchasmanufacturing,healthcare,andtelecommunications.Thediagnosticprocessinvolvesidentifyingtherootcauseofaproblemanddevelopinganeffectivesolution.Traditionally,single-stepandmulti-stepoptimizationtechniqueshavebeenemployedindependentlyfordiagnosticpurposes.However,anintegrationofbothstrategiescanprovideamorecomprehensiveandefficientapproachtofaultdiagnosis.Thispaperaimstoexploretheconstructionofadiagnosticstrategythatcombinessingle-stepandmulti-stepoptimizationmethodstoimprovediagnosticaccuracyandefficiency.
