机电设备备件的多级虚拟联合库存模式研究重庆大学硕士学位论文学生姓名:黄晓诗指导教师:陈晓慧教授专业:工业工程学科门类:工学重庆大学机械工程学院二O一一年五月StudyonVirtualJMImodelofElectromechanicalEquipmentSpareParts’Multi-EchelonInventoryAThesisSubmittedtoChongqingUniversityinPartialFulfillmentoftheRequirementfortheDegreeofMasterofEngineeringByHuangXiaoshiSupervisedbyProf.ChenXiaohuiMajor:IndustrialEngineeringCollegeofMechanicalEngineeringofChongqingUniversity,Chongqing,ChinaMay2011重庆大学硕士学位论文中文摘要I摘要机电设备备件库存是专为机电设备维修而进行的储备。随着由经济的全球化而产生的跨国跨域供应问题的出现,备件供应成本控制与柔性水平也愈发显得重要。本文提出了机电设备备件的多级虚拟联合库存模式,构建了相应的管理系统,建立了补货成本数学模型和供应柔性评价体系,并通过仿真实验验证了新模式的优越性。理论阐述部分,围绕供应链库存的一般管理模式,重点描述联合库存管理(JMI)模式,简要介绍了虚拟联合库存模式,然后针对多级库存的库存策略,从中心化控制策略和非中心化策略、多级库存盘存及订货策略、缓冲库存协调策略三方面详细地进行了总结归纳。基于对备件的库存和供应特点的分析,针对传统备件供应和库存中出现的问题,建立了由备件供应商、虚拟分销中心、分销点组成的多级虚拟联合备件库存系统,对传统企业备件库存管理运作模式和业务流程进行了改进,并展开了多级虚拟联合备件库存实现的支撑技术设计。对所建立的虚拟联合库存系统的备件供应采用纵向订货与横向调拨相结合的补货控制模式。建立补货成本数学模型来描述库存需求随机情况下,如何确定各地区有效合理的(R,Q)库存控制策略,使得整条供应链的补货总成本之和最小的问题。建立起供应系统柔性评价的评价指标体系,以便对前述多级虚拟联合备件库存系统的供应柔性进行考评。结合M公司实际案例,在分析了供应链库存系统仿真建模的方法和基于仿真的粒子群优化方法的理论基础上,对本文所建立多级虚拟联合库存系统补货成本模型建立仿真模型,引入粒子群优化算法,以补货成本最低原则,寻求最优的(R,Q)策略组合。通过调整模型的库存策略及调拨流程,比较分析改变前后的库存成本和柔性指标,证明所建立的虚拟联合库存模式优于传统库存模式。关键词:备件管理联合库存虚拟库存成本控制策略柔性评价重庆大学硕士学位论文英文摘要IIABSTRACTSparepartsinventoryiscarriedoutforequipmentmaintenancereserves,theircostcontrolandflexibilityaregettingmoreandmoreimportantwiththetransnationalsupplyproblemwitheconomyglobalization.Thispaperestablishedamulti-echelonvirtualJMIinventorymodelforthesparepartsofelectromechanicalequipments,acorrespondingmanagementsystemwasconstructed,therelevantmechanismsisdescribed,alsoaflexibilityevaluationmodelandamathematicalsupplyreplenishmentcostmodelaregiven,thenewmodel’ssuperiorityisshowedbysimulationresults.Thetheoreticalparagraphexplainedthegeneralmodernmanagementmodesonsupplychaininventory,especiallyJointManagementInventory(JMI)mode,thebasicconceptsaboutvirtualJMImodewerealsointroduced.Itsummarizedmulti-echeloninventorycontrolstrategyinthreeaspects:Centralizingorun-centralizingstrategies,orderingstrategies,bufferinginventorycoordinationstrategies.Amulti-echelonvirtualJMIinventorysystemconsistsofsparepartssuppliers,distributioncenterandretailstoreswasestablishedafterananalysisoftheinventoryandsupplycharacteristicsofspareparts,facingtoproblemsintraditionalsparepartssupplyandinventorysystem.Managementbusinessprocessesforsparepartsinventorywasimproved.Acorrespondingmanagementsystemforthismulti-echelonvirtualJMIinventorymodelwasdesigned.Anorderingstrategyandacrossstrategywereusedintheinventoryreplenishmentcontrolmodel.Amathematicmodelforinventoryreplenishmentcostwasbuiltbasedonstochasticdemands.Researchesfocusonhowtodeterminetheveryparametersof(R,Q)inventorycontrolstrategyforeachregion,soastolowestthewholesupplychain’stotalinventoryreplenishmentcost.Anindexsystemofflexibilityevaluationwasalsoestablishedtotestthenewsystem.CompanyMservedactualcases.Theabovemathematicmodelofmulti-echeloninventoryreplenishmentcostwasbuiltintoacomputersimulationmodelafterananalysisofinventorysystemsimulationmodelingmethodsandthesimulation-basedParticleSwarmOptimization(PSO)method.BasedonthosetheorythispaperintroducedPSOtothesearchtheoptimal(R,Q)parameterscombination.Testsbyadjustingtheorderingstrategyandacrossstrategyprocesses,comparinginventory重庆大学硕士学位论文英文摘要IIIcostsandflexibilitybeforeandafterchanges,resultsprovethatthenewmodewassuperiortothetraditionalone.Keywords:sparepartsmanagement,JMI,virtualinventory,costcontrolstrategy,flexibilityevaluation重庆大学硕士学位论文目录IV目录中文摘要..........................................................................................................................................I英文摘要........................................................................................................................................II1绪论..............................................................................................................................................11.1本文研究背景与意义...........................................................................................................11.2国内外研究综述...................................................................................................................21.2.1备件管理研究现状...................................................................................................21.2.2备件的联合库存管理研究现状...............................................................................31.2.3多级库存控制策略研究现状...................................................................................41.2.4小结...........................................................................................................................61.3本文的主要研究内容...........................................................................................................62基于供应链的库存控制理论.........................................................................................82.1供应链库存管理...................................................................................................................82.1.1现代供应链库存管理模式..................................................................
