主成分分析在企业物流绩效评价中的应用VIP免费

大学毕业设计（论文）摘要根据现代竞争理论，企业要取得竞争优势必须巩固和扩展自身的核心业务。而物流已经成为企业在降低物资消耗，提高劳动生产率以外的第三利润源泉。通过企业物流进行绩效评价，能够帮助企业正确判断实际的经营水平，及时发现自身的优势和不足，从而为全面监督企业资源，实现资源的合理配置，提高企业的核心竞争力提供科学的依据。本文设计了一个比较全面的指标体系，综合考虑企业物流的财务绩效，客户绩效，市场绩效，业务绩效以及创新学习绩效等五类指标。基于主成分分析（PCA）方法，将多指标问题转化为较少的综合指标，从而给出了较为客观的权重，对企业物流绩效进行了综合评价。并探讨了主成分分析的不足，提出了加权主成分分析法（WPCA），体现决策者的偏好程度。然后将层次分析法（AHP）和主成分分析法（PCA）结合起来，提出了一种类加权主成分分析法（CWPCA）并建立了综合评价模型应用于企业物流绩效评价，更加符合客观事实。实例分析表明该方法能有效地评价企业物流绩效，符合客观事实，评价结果全面，合理。关键词：物流绩效；综合评价；主成分分析；加权主成分分析I大学毕业设计（论文）AbstractAccordingtothemoderncompetitiontheory,enterprisesgettheadvantagesofcompetitionbyconsolidatinganddevelopingtheircorebusiness.Andlogisticsbecomesthethirdprofitfountainbesidesdecreaseofmaterialconsumptionandraiseoflaborproductivity.Throughintegratedevaluationonlogisticsperformance,enterprisecouldestimatetherunninglevel,findthedisadvantagesandshortcomings.Also,theperformanceevaluationprovidesthescientificbasisforcontrollingenterpriseresource,enhancingcore-competitiveness.Thispaperdesignsanindexessystem,consideringfinancialaffairs,customers,markets,business,andinnovation.TheevaluationonlogisticsperformancebasedonPrincipalComponentAnalysisturnsMulti-indextoLess-index,andamoreobjectiveweightisputforward.AfterfindingthedisadvantagesofPCA,WeightedPrincipalComponentAnalysisispresented,whichreflectsthepreferencesofdecision-makersandreality.ThencombiningtheanalytichierarchyprocesswiththePrincipalComponentAnalysis,wepresentClassWeightedPrincipalComponentAnalysis.Accordingtothis,amodeliscreatedforlogisticsperformanceevaluationofenterprise.Anexampleshowsthismethodcanevaluatethelogisticsperformanceeffectively.Evaluationresultsaremoreobjectiveandrational.Keywords：PCA，WPCA，CWPA，Logistics，IntegratedEvaluationII大学毕业设计（论文）目录摘要.........................................................................................................................................IAbstract......................................................................................................................................II1绪论.........................................................................................................................................11.1企业物流绩效评价方法研究的背景和意义..................................................................................11.2企业物流绩效评价方法研究的现状..............................................................................................21.2.1国内物流绩效评价方法研究的现状...................................................................................21.2.2国外物流绩效评价方法研究的现状...................................................................................41.3本文研究的内容与目标..................................................................................................................51.4本章小结........................................................................
