基于灰色关联分析-层次分析法的机械加工工艺评价 Title:MechanicalMachiningProcessEvaluationBasedonGreyRelationalAnalysis-AnalyticHierarchyProcess Introduction: Mechanicalmachiningplaysanessentialroleinthemanufacturingindustry,contributingtoproducinghigh-qualityproductswithaccuratedimensionsandsurfaceroughness.Evaluatingtheeffectivenessofmechanicalmachiningprocessesiscrucialforimprovingproductivity,reducingcosts,andensuringproductquality.Inthispaper,weproposeacomprehensivemethodthatcombinesgreyrelationalanalysis(GRA)andtheanalytichierarchyprocess(AHP)toassessthemachiningprocessperformance. GreyRelationalAnalysis(GRA): Greyrelationalanalysis,developedbyDengJulong,isapowerfultoolforevaluatingthecorrelationbetweendifferentfactors.Unliketraditionalstatisticalmethods,GRAissuitableforanalyzingsystemswithlimitedorincompleteinformation.GRAcalculatesthegreyrelationalcoefficient(GRC)betweenthereferencesequenceandthecorrespondingcomparativesequence.ThehighertheGRCvalue,thestrongertherelationshipbetweenthetwosequences.GRAhasbeenwidelyappliedinvariousfields,includingengineering,economics,andmanagement.
