基于模糊AHP地铁备件供应商的选择及管理

基于模糊AHP的地铁备件供应商选择研究及管理专业：物流管理学号：20090210120118姓名：李阳春指导老师：王浩伦摘要地铁设备不仅是企业固定资产的重要组成部分，也是一个企业技术装备水平的重要标志，是企业赖以正常生产经营和参与市场竞争的物质技术基础。在其他行业，备件原因导致的生产停顿仅影响到商品的正常生产，影响限于经济效益。地铁行业如因备件导致地铁故障和停运，不仅可能威胁大众的人身和财产安全，而且还会引起城市主要交通的瘫痪，影响整个城市的正常秩序。所以在选择供应商保证设备的质量和服务方面要比其他的企业更重要，这里用模糊AHP法说明了选择最佳供应商的方法。其二，在管理方面也是很重要的。设备管理应该包含两个方面：1、对于设备操作、维护、修理和相关人员的管理;2、对于设备本身的规划、制造、使用、维修等等各方面的管理。自从资本主义的工业化革命以来，设备管理经历了经验管理、科学管理、现代管理多个阶段。目前，随着设备本身的不断变化，计算机技术和诊断技术的飞速发展，设备管理有了许多新的手段。如计算机诊断技术、ERP技术。地铁备件种类繁多、数量众多，涉及车辆、通信、信号、供电、轨道、线路、车站机电、自动售检票等设备，且进口备件较多，其种类、数量是其他公共交通行业无法比拟的。地铁备件对地铁运营至关重要。在其他行业，备件原因导致的生产停顿仅影响到商品的正常生产，影响限于经济，也会造成重大的事故。【关键词】：备件供应商供应商选择评价模糊AHP法管理AbstractThesubwayequipmentisnotonlyanimportantpartofcorporatefixedassets,isalsoanimportantindicatoroftheleveloftechnicalequipmentandmaterialandtechnicalbasisonwhichthenormalproductionandoperation,andtoparticipateinmarketcompetitionenterprise.Inotherindustries,theproductionofsparepartscausespausesonlyaffectthenormalproductionofgoods,theimpactoflimitedeconomicbenefits.Metroindustriessuchassubwayfailureandoutageduetosparepartsmayposeathreatnotonlytothepersonalandpropertysafetyofthegeneralpublic,butalsocauseparalysisofthecity'smaintraffic,affectingthenormalorderoftheentirecity.Therefore,inthechoiceofsupplierstoensurethequalityoftheequipmentandservicesismoreimportantthanotherenterprises,FuzzyAHPandselectthebestsupplier.Second,inthemanagementisalsoveryimportant.DeviceManagershouldcontaintwoaspects:1,equipmentoperation,maintenance,repair,andpersonnelmanagement;2,forthemanagementofallaspectsofequipmentplanning,manufacturing,use,maintenance,andsoon.Sincecapitalismsincetheindustrialrevolution,thedevicemanagementexperienceexperienceinmanagement,scientificmanagement,modernmanagementofmultiplestages.,Withthedeviceitselfchangingcomputertechnologyandtherapiddevelopmentofdiagnostictechniques,equipmentmanagement,therehavebeenmanynewmeans.Suchascomputerdiagnostictechnology,ERPtechnology.Widerangeofmetrospareparts,alargenumberinvolvingvehicles,communications,signal,powersupply,track,line,stationelectromechanicalautomaticfarecollectionandotherequipment,andmoreimportedspareparts,itstype,quantitycannotbecomparedtootherpublictransportindustry.Subwaysparepartsofmetrooperatorsisessential.Inotherindustries,theproductionofsparepartscausespausesonlyaffectthenormalproductionofgoods,limitedtotheeconomicimpact,andcanalsocauseamajoraccident.Keywords:SparepartssupplierSupplierevaluationandselectionFuzzyAHPmethodAdministration目录第一章1绪论····························································································11.1研究意义及背景···············································································11.1.1选题的背景··············································································11.1.2地铁有关设备简介（以上海地铁为例）·········································11.1.3选题的意义··············································································21.2理论综述························································································31.2.1问题分析················································································3第二章2研究理论基础·················································································82.1供应商评价和选择方法······································································82.2模糊AHP方法················································································102.2.1基于正闭区间数判断矩阵的模糊AHP法······································102.2.1.1区间数与区间数矩阵·······················································102.2.1.2区间数判断矩阵及其一致性··············································112.2.1.3区间权向量及特征向量方法···············································132.2.1.4层次的组合区间权及排序·················································13第三章3备件供应商评价模型······································································153.1备件供应商评价目标········································································153.2评价指标构建原则···········································································163.3备件供应商评价流程·········································································173.4案例分析·······················································································19第四章4设备管理存在的差距与改善对策·······················································224.1上海地铁与同行业先进水平的差距·······················································224.1.1设备前期管理的差距································································224.1.1.1体制方面的差距······························································234.1.1.2设备原始设计、制造的差距···············································234.1.2备件管理水平上的差距·····························································234.2存在差距的主要原因·········································································254.2.1设备初期管理的差距原因分析····················································254.2.1.1没有以运营为中心，导致运营质量指标下降··························254.2.1.2法规、标准、规程建设滞后···············································254.2.1.3设备依赖进口·································································254.2.2备件管理水平差距的原因分析·················································
