每年需采购某种产品732件。该产品的订货成本为45元，储存成本为每年15元，该产品的折扣策略如下表。,64,通过计算得出EOQ=66件此时总成本为TC66=732*20+732/66*45+1/2*66*15=15634比较TC80=732*18+732/80*45+1/2*80*15=14188TC100=732*17+732/100*45+1/2*100*15=13523最佳订货量Q*=100,65,作业：A公司以单价10元每年购入某种产品8000件。每次订货费用为30元，资金年利息率为12%，单位维持库存费按所库存货物价值的18%计算。若每次订货的提前期为2周，试求经济订货批量、最低年总成本、年订购次数和订货点。,66,三、多周期库存模型的订货时点多周期库存模型的假设：需求是随机的，服从一定的随机分布。每次订货，需要支付一个固定的成本C0，再加上与订购数成比例的费用。如果发出一个订单，供应商在经过一定提前期后到达，提前期可能是固定的也可能是随机的。如果顾客订单到达时，手头无存货满足顾客需求，这笔订单就会失去。规定一个必须的服务水平。服务水平是提前期中不出现缺货的概率。如，供应商希望确保提前期内至少能满足95%的顾客需求，则服务水平为95%。,67,1不确定条件下再订货点的确定（1）需求不确定条件下的再订货点（ROP）ROP由两部分组成：提前期内的平均库存水平，LTd安全库存ssROP=dLT+ZSdLT1/2,68,（2）提前期不确定条件下的再订货点当提前期不确定时，定义平均提前期为T，提前期的标准差为sLT，此时的安全库存量为：ss=ZdsLT，此时的再订货点为ROP=dLT+ZdsLT,69,（3）需求和提前期不确定条件下的再订货点可以通过将需求波动和提前期波动累加得出需求和提前期不确定条件下的合成标准差。,70,CombiningDemandandLeadTimeUncertainty,LeadTimeLT=10LT=2.00,+,DemandDD=5DD=2.54,AverageLTD(Leadtimedemand)=LT*DD=50,=,10-71,McGraw-Hill/Irwin,SupplyChainLogisticsManagement,FirstEdition.Bowersox,Closs,andCooper.Copyright2002byTheMcGraw-HillCompanies,Inc.Allrightsreserved.,例5.5某制造商销售一种零件，每天的平均需求为100件，订货提前期为4天（1）设需求呈正态分布，且需求相互独立，需求的标准差为30件，当客户服务水平为99%时，其安全库存量为多少？再订货点是多少？（2）若需求稳定，但是订货完成周期服从正态分布，并且其标准差为4天，当客户服务水平为99%时，该企业需要持有的安全库存量是多少，再订货点是多少？（3）若需求服从标准差为30的正态分布，并且提前期也是变化的，提前期的标准差为4天，当客户服务水平为99%时，该企业需要持有的安全库存量是多少，再订货点是多少？,72,作业：定量订货策略下苏宁零售店苹果手机的安全库存问题,73,在苏宁的一家零售店里苹果手机一周的需求量呈正态分布,其均值为300,标准差为200。苹果公司要花两周的时间为苏宁提供定货。苏宁公司确定补给周期供给水平为95%，并且对库存情况进行连续监控。问：苏宁零售店应该保持手机的安全库存量是多少？再定货点应该是多少？,一、库存的ABC分类管理ABC分类管理方法就是将库存物品按重要性程度分为特别重要的库存（A类库存），一般重要的库存（B类库存）和不重要的库存（C类库存）三个等级，然后针对不同的级别分别进行管理和控制。将商品按其库存额从大到小进行排序，并算出总库存额；计算累计库存额占总库存额的百分比；按累计库存百分比划分A、B、C类。,74,75,76,ABC分类管理,ProductClassificationAnalysis(ABC),SampleIntegratedStrategy,SupplyChainLogisticsManagement,Chapter11:TransportationInfrastructureandRegulation,TransportationManagement,DiscussionTopicsTransportationInfrastructureIntegratedTransportationDecisions,Supplier,Manufacturer,Customer,Inbound,Outbound,Product/InfoFlows,Info/ReturnGoodsFlows,TransportationValueContribution,FreightTransportationModes,CostStructureServiceCapabilities,TransportationInfrastructure,TransportationModes,RailMotorAirWaterPipelineIntermodal“Premium”,BasicModesofTransportation,FixedcostsVar.costsTrafficcompositionRailhighlowbulkfood,mining,heavymfgMotorlowmediumconsumergoods,medium/lightmfgWatermediumlowbulkfood,mining,chemicalsAirlowhighhigh-valuegoods,rushshipmentsPipehighlowpetroleum,chemicals,mineralslurry,RelativeServiceCharacteristics,OperatingcharacteristicsRailMotorWaterAirPipeSpeed32415Availability21435Dependability32451Capability23145Flexibility31425Composite1391715211=best,5=worst,Intermodal,Rail,Air,Water,Truck,TransportPrinciplesEconomiesofScale,$/wgt.,Sizeofshipment,TransportationCostTheory,EconomyofScale1,Costperunit,Volume,LTL,TL,15,000lbs.,TransportationCostTheory(cont.),EconomyofScale2,Costperunit,Density,LTL,TL,TransportPrinciplesEconomiesofDistance,$/wgt.,ShipmentDistance,“TaperingPrinciple”,TransportationFormats,CommoncarriersContractcarriersPrivatecarriersExemptcarriersNon-operatingintermediariesFreightforwardersShippersAssociations/CooperativesandAgentsBrokers,ChangingTransportationEnvironment,DeregulationTime-basedcompetitionExpandinggeographiccoverageInformationtechnologyIntermodal,Mode,CarrierClass,Carrier,DiscreteSteps,TraditionalMode/CarrierSelection,IntegratedMode/Class/CarrierSelection,Mode/Class/CarrierIntegratedDecision,Customerservice/transittimerequirements,Transportationcostconstraints,Integratedtransportationcarrierdatabase(allpossiblemodes/types/carrierswithpricing),Market/productcharacteristics,CarrierSelection,TransportationCosts,ProductrelatedDensityStowabilityEase/difficultyofhandlingLiability,MarketrelatedCompetitionlevelLocationofmarketsNatureandextentofregulationBalanceoffreighttrafficSeasonalityofproductmovementsDomesticvs.International,PricingandRateNegotiations,ratevariance,Marketrelatedvalue,MaximumRate,MinimumRate,Product/servicerelatedcost,competition,marketlocation,regulations,freightbalance,seasonality,international,distance,density,stowability,handling,liability,TransportationRegulatoryEnvironment-Economic,ObjectivesConsumerandmarketprotectionIndustrystabilityImposeintegrityonindustrypracticesTypesofeconomicregulationEntryRatesServicesExit,TransportationRegulatoryEnvironment-Safety,ObjectivesEmployeeandpublicprotectionEnvironmentalprotectionTypesEquipmentEnvironmentalconstraintsOperatorconstraintsHazardousmaterial,SupplyChainLogisticsManagement,Chapter12:TransportationManagement,IntegratedTransportationDecisions,Supplier,Manufacturer,Customer,Inbound,Outbound,DecisionFlow,Strategic,Operational,Macro,Micro,DecisionScope,Totalnetworkandlanedesigndecisions,Dockleveldecisions,Laneoperationdecisions,Mode/carrierselectiondecisions,Ratenegotiations,12-100,McGraw-Hill/Irwin,SupplyChainLogisticsManagement,FirstEdition.Bowersox,Closs,andCooper.Copyright2002byTheMcGraw-HillCompanies,Inc.Allrightsreserved.,NetworkFreightFlows,(S=supplier,P=plant,W=warehouse,C=customer),S,S,S,S,P,P,P,P,W,W,W,C,C,C,C,
