CIMSistheintegrationofmultiplesubsystemswithdifferentdegreesofautomation,suchasManagementInformationSystem(MIS),ManufacturingResourcePlanningSystem(MRPII),ComputerAidedDesignSystem(CAD),ComputerAidedProcessDesignSystem(CAPP)),computer-aidedmanufacturingsystem(CAM),flexiblemanufacturingsystem(FMS),andnumericallycontrolledmachinetools(NC,CNC),robots,etc.CIMSisdevelopedonthebasisoftheseautomationsystems.Accordingtotheneedsandeconomicstrengthofenterprises,CIMSrealizesinformationintegrationandfunctionalintegrationofvariousautomationsystemsthroughcomputers.Ofcourse,thesesubsystemsalsousedifferenttypesofcomputers,andsomesubsystemsarealsointegrated.Forexample,MISrealizestheintegrationofmultiplemanagementfunctions,FMSrealizestheintegrationofprocessingequipmentandmaterialconveyingequipment,andsoon.Buttheseintegrationsareinsmallerparts,andCIMSisfortheintegrationoftheentirefactoryenterprise.CIMSisfortheentireenterprise,coveringavarietyofbusinessactivitiesoftheenterprise,includingproductionandoperationmanagement,engineeringdesign,andproductionandmanufacturing,thatis,startingfromproductquotationandorderacceptance,throughplanning,design,andmanufacturinguntilproductdeliveryandafter-salesservice,etc.Thewholeprocess.
