基于VE的摩托车产品功能分析与评价研究学位论文学生姓名：指导教师：育教授专业：机械设计及理论学科门类：工学机械工程学院二O一零年三月硕士学位论文中文摘要I摘要随着经济的快速发展，产品市场竞争的加剧，利润空间受到很大压缩，摩托车企业都在致力于自身产品竞争力的建设。价值工程作为一门独特的思想及管理方法贯穿于产品设计的全过程，并根据产品定位的不同指导产品的开发，协调产品设计开发中安全性、经济性、适用性等性能间的相互关系，并寻求功能与成本之间最佳的对应配比，以尽量小的成本实现产品功能，提高产品质量，进而提高产品的竞争力。本文针对摩托车产品设计的特点，借助价值工程的理论、技术及工作方法，在理念层面上，提出将价值工程思想融入到摩托车产品的设计中，使摩托车产品设计更为系统有效，满足用户不断变化的需求；在方法层面上，采用价值工程方法对其功能进行系统分析和评价，并运用网络分析法求得功能权重，并将研究成果应用到具体的摩托车产品设计中。论文的主要研究内容如下：首先，论文通过对国内外价值工程应用情况、理论研究现状及发展趋势等方面进行分析，为摩托车产品设计提供理论支持。其次，针对摩托车产品的特点，阐述摩托车产品价值工程对象选择的原则及方法，对摩托车产品的功能进行定义、分类及整理，梳理摩托车的功能逻辑，建立摩托车功能系统图，研究摩托车性能特点，并结合摩托车功能系统图，建立功能设计模型。第三，对目前常用的几种功能权重的求解方法进行比较分析，根据摩托车产品设计过程的多目标、多准则及非独立递阶的特点，采用了网络分析法求解摩托车产品的功能权重，详细描述了基于网络分析法的摩托车产品的功能重要度求解过程，并对摩托车产品进行了功能评价。最后，基于以上的理论研究，将研究成果应用到某摩托车集团A款摩托车，求得其功能权重、零部件功能成本系数及价值系数，对各个零部件的可改善度进行分析，找出了该款产品的价值工程改善对象。验证了本论文提出的摩托车产品功能设计模型的正确性及ANP求解算法的可行性。关键词：价值工程；摩托车；功能分析；功能评价；网络分析法硕士学位论文英文摘要IIABSTRACTWiththerapideconomicdevelopment,productmarketcompetitionintensifies,profitmarginhasbeengreatlycompressed,andmotorcyclecompaniesarededicatedtotheirownproductscompetitivenessbuilding.Valueengineeringasauniquewayofthinkingandmanagementmethodsisthroughouttheentireprocessofproductdesignandinaccordancewiththedifferentproductspositioningtoguideproductdevelopment,tocoordinatesafety,economy,fitnessperformance,inter-relations,andtoseekthebestfunctionandthecorrespondingratiobetweenthecostandfunction，toachieveproductfunctionsandimprovetheproductqualitybythecostaslowaspossible,therebytoimproveproductcompetitiveness.Thispaperisintheviewofsomecharacteristicsofmotorcycleproducts,andvalueengineeringconceptsandmethodsofworkhasbeenused.Attheconceptuallevel,thevalueengineeringideawasapposedintothedesignofmotorcycleproductssothatmotorcycleproductdesignwouldbemoresystematicandeffectivethatcanmeetthechangingdemandoftheuser；atthemethodologicallevel,thevalueengineeringmethodologywasusedforsystemanalysisandevaluationofitsfunction,andanalysiscapabilitiesimportantcoefficientsobtainedbyusinganalyticnetworkprocess,andallresearchisappliedintothespecificmotorcycleproductdesign.Thecontentsofthepaperareasfollows.First,thepaperanalysestheapplicationofvalueengineering，theoreticalresearch，developmentandtrendsathomeandabroad，providingtheoreticalsupportforthemotorcycledesign.Second,intheviewofmotorcycleproductcharacteristic,thepaperintroducesmotorcycleproductvalueengineeringprinciplesandmethods,thedefinition,classification,reorganizationofmotorcycleproductsfunctionsaredone,andmotorcyclelogicalfunctionsofarecombed,themotorcyclefunctionanalysissystemtechniqueisbuild,intheviewofperformancecharacteristicsofmotorcycleandmotorcyclefunctionanalysissystemtechniqueisstudied,themotorcyclefunctionaldesignmodelisestablished.Third,severalfeaturesofthecurrentcommonlyusedforsolvingtheimportantcoefficientshavebeendoneforacomparativeanalysis,accordingtomotorcycleproductsmulti-objective,multi-criteriaandcharacteristicsofnon-independent硕士学位论文英文摘要IIIhierarchical,anetworkanalysismethodisusedtosolvetheimportantfunctionofmotorcycleproducts,adetaileddescriptionofthesolutionprocessofanalysisofthefunctionofanimportantdegreeofmotorcycleproductswhichisbasedonanalyticnetworkprocess,andthemotorcycleproductsfunctionalevaluationisdone.Finally,basedontheabovetheoreticalresearch,alltheresultswillbeappliedinamotorcyclesectionofAmotorcyclegroup,functionweightandpartscostfactorandthevaluefunctioncoefficientsareobtained,individualcomponentswhichcanbeimprovedareanalyzedandthemodelofproductvalueengineeringimprovementobjectarefoundout.Throughtheapplication，theaccuracyofthismodelandthefeasib
