【正文】 實驗室Outline161。 計劃與控制的層次系統(tǒng)161。一般來說，凈利潤越高的企業(yè)，其效益越好 161。沒有一定的現(xiàn)金流量，企業(yè)也就無法生存下去 實現(xiàn)企業(yè)目標(biāo)的三條途徑161。 企業(yè)目標(biāo)及其實現(xiàn)161。 混流固定比例流水線排產(chǎn)模型與應(yīng)用161。 廣義與狹義生產(chǎn) /運作系統(tǒng)161。161。 庫存? 主要指供應(yīng)鏈各級企業(yè)間的產(chǎn)成品與原材料庫存161。 物料 (Parts)? 庫存管理，供應(yīng)商 /采購管理，內(nèi)部物流管理161。 生產(chǎn)與運作管理研究領(lǐng)域161。 HFC1061制動系統(tǒng)試驗設(shè)計與分析計劃與控制的層次系統(tǒng)PersonnelPlanFORECASTINGCAPACITY/FACILITYPLANNINGWORKFORCE PLANNINGMarketingParametersProduct/ProcessParameters LaborPoliciesCapacityPlanAGGREGATEPLANNINGAggregatePlan StrategyWorkScheduleWIP/QUOTASETTINGDEMANDMANAGEMENTSEQUENCING SCHEDULINGCustomerDemandsMasterProductionScheduleSHOP FLOORCONTROLWIPPosition TacticsREALTIMESIMULATIONPRODUCTIONTRACKINGWorkForecastControlAggregating Planning by Time HorizonForecasting161。 Delphi161。 Time series modelsCapacity/Facility Planning161。 Modern:? congestion (CT) increases with utilization? CT and responsiveness are tied to capacity decisions?

Aggregation: product families and time periods must be set appropriately for the environment.? Coordination: AP is the link between the high level functions of forecasting/capacity planning and intermediate level functions of quota setting and scheduling.? Anticipating Execution: AP is virtually always done deterministically, while production is carried out in a stochastic environment.? Linear Programming: is a powerful tool wellsuited to AP and other optimization problems.Aggregate Planning Conclusions161。 Robustness matters more than precision161。 Increased throughput.161。 High Customer Service: ontime delivery161。 Fill Rate:?
