MPC教育资料1：什么是PC2：什么是MPC3：MPC需要关注和解决那些问题4：MPC专业词汇解释什么是PCPC就是productioncontrolPC是着眼在公司层面，根据销售订单以及生产线产能进行制定生产投入产出计划职责：产品的投入计划确保产品交货期，以及产出计划。确认制品MOVE情况以及提醒交货期会有延迟的产品执行客户需求的产品释放以及停滞等等什么是MPCMPC的客户是MPP,MPP客户是PC。也就是说详细的完成PC所下达的任务。按生产计划检查、跟踪并准确及时报告生产流程中的问题。依据WIP、制品交期、设备负荷、制程时间限制以及在制品及设备的运行状况等因素调整实时调度系统的运行

提高人员及设备利用率制品流通率的管理及有关数据的提供依据生产数据计算生产能力。MPC需要解决哪些问题Themissionofamanufacturingfab:TosatisfycustomerandmaximizethecapacityandwaferoutputWhatcustomerwants?OntimedeliveryGoodwaferqualityLowunitpriceMFGindicesindicatestheperformanceofaFabIndexnameShortdescCTCycleTimeTRTurnRatioMoveWafermovementWIPProductionwaferinprocessEngWIPEngineerwaferinprocessYieldFabYieldHoldHoldWIPTerminateEngineerwaferscrapScrapProductionwaferscrapReworkReworkwaferWSWaferstartWOWaferoutKEYC/T英文全名：Cycle/Time中文全名:运转周期定义:theaverageleadtimewhichonewafermustpayforrunning,waiting,holding,andtimeonbankfromwaferstarttoQC-Inspection计算方式:∑Cycle_Time_Waferi/Wafer_Output
