哈尔滨工业大学工程硕士学位论文--I摘要产品数据是企业生产赖以正常运转和企业发展的重要资源，产品数据的管理和复用是当前国内绝大多数开发设计型企业急待解决的最重要问题之一。企业经营运作的核心就在于降低产品成本、优化产品质量、提高产品开发速度，从而赢得更多的利润。开发成本和时间通常在整个产品的成本中占有最大的比重，并且关乎最终产品的市场反映度。要想降低开发成本、提高产品质量，必须想办法在企业的开发过程中优化开发质量和降低开发成本。在飞速发展的信息时代，企业竞争实力的积聚，更加依赖于信息技术和管理技术的有机结合。以制造业为代表，越来越多的企业采用PDM(ProductDataManagement)这种先进的集管理和信息技术于一体的管理理念，并在实践中取得了良好的效果。神舟AVIDM(AerospaceVehicleDesignandManufa-ctureSystem)充分吸收国内外先进产品数据管理思想和最新技术，针对目前航天系统急剧膨胀数据的管理中遇到的困难，构建了一个基于Web的、从设计、生产到管理综合集成的协同设计产品研制管理系统。本文以北京神舟航天软件技术有限公司AVIDM系统工程为应用实例，针对其产品结构与配置管理系统业务流程进行开发。系统应用目前广泛应用的MVC(Model-View-Controller)软件设计模式，采用Browser/Server软件体系结构，综合应用了J2EE(Java2Platform,EnterpriseEdition)平台的多种技术。针对航天科技集团公司的现状，产品结构与配置管理系统开发了零部件管理、版本管理、变更管理和工具管理等几个子功能模块，以提高企业的信息化程度，降低企业的开发设计成本，缩短企业开发周期，增加企业的经济效益，增强企业的市场竞争力。由于航天科技集团是典型制造机械类企业，代表了我国机械制造业最尖端生产力，因此其产品数据管理中存在的问题也是机械制造业普遍存在的问题。本文的研究将对机械行业产品数据管理具有一定的借鉴和参考作用。关键词产品研制管理；协同设计；AVIDM哈尔滨工业大学工程硕士学位论文--IIAbstractProductdataisthemostimportantresourceofenterprise'sdevelopmentsandbusiness,howtomanagerandreuseproductdataisoneseriousquestionindireneedofquestions.Thebusinessenterpriseconductsthecoreoftheoperationtocutdowntheprimeproductcost,optimizeproductquality,improveproductdevelopingrate,thuswinmoreprofits.Usuallythedevelopmentcostandtimewouldoccupythebiggestspecificweight,associatetofeedbackofmarket.Towanttolowerthedevelopmentcostandtime,mustfindwaysandmeanstocontrolthedevelopmentcostandtimeinthedevelopmentactivityofbusinessenterprise.Attheinformationagethatisdevelopingatfullspeed,thecongregatingofenterprisecompetitivestrengthdependsincreasinglyontheorganiccombineofinformationtechniqueandmanagementtechnique.Takemanufacturingindustryastherepresentative,moreandmoreenterpriseadoptPDM(ProductDataManagement),anadvancedmanagementtheorieswhichgathermanagementandinformationtechniqueinone,andobtainedagoodresultinthefulfillment.AVIDM(AerospaceVehicleDesignandManufactureSystem)absorbstheforeigndevelopedmanagementthoughtandlatesttechniqueamply,putsforwardthemanagementembarrassmentincludingrapidityincreaseproductdata,constructadistributedintegratingsystematicplatformandincoordinationwiththeworkingenvironmentfromdesigning,producingtomanagementbasedonweb.ThistexttakestheBeiJingShenZhouAerospaceTechnologycompanyLtd.AVIDMsystemengineeringasthelivingexample,directingagainsttheproductstructureandconfiguremanagementsystembusinessprocesstocarryonthedevelopmenttoit.SystemappliesMVC(Model-View-Controller)softwaredesignmodethatiscurrentlyextensivelyused,andadoptsBrowser/Servesoftwaresystemstructure,comprehensivelyappliesvarioustechniqueoftheterraceofJ2EE(Java2Platform,EnterpriseEdition)currently.AimingatthepresentconditionoftheChinaAerospaceTechnologyGroup,theproductstructureandconfiguremanagementsystemdevelopedtheitemmanagement,哈尔滨工业大学工程硕士学位论文--IIItheversionmanagement,thechangemanagementandthetoolmanagementetc.toraisetheinformation-baseddegreeofthebusinessenterprise,lowerthedistributioncostofthebusinessenterprise,decreasethedevelopingcycle,increasetheeconomicprofitofthebusinessenterprise,andstrengthenthemarketcompetitionabilityofthebusinessenterprise.BecausetheChinaAerospaceTechnologyGroupistypicalenterprisewhichmakesthemachineryprimarily,ithasrepresentedthemostadvancedprolificacyinmechanicalmanufacturingindustryinourcountry,thereforethequestionexistingintheproductdatamanagementinChineseAstronauticsScienceandTechnologyGroupalsorepresentuniversalquestionsinthemajorityofmechanicalmanufacturingindustries.Thisresearchinthisarticlewillmakeeffectofreferenceandsupportinthemechanicalprofessionproductdatamanagement.KeywordsProductdesignmanager,Cooperationdesign,Aerospacevehicledesignandmanufacturesystem哈尔滨工业大学工程硕士学位论文--IV目录摘要................................................................................................................IAbstract..............................................................................................................II第1章绪论.......................................................................................................11.1课题的背景及研究目的.........................................................................11.2与课题相关的国内外研究综述..............................................................21.2.1PDM的产生......................................................................................21.2.2PDM在国外发展状况.......................................................................31.2.3PDM在国内发展状况.......................................................................41.3本论文的主要工作内容.........................................................................6第2章产品数据管理技术分析........................................................................72.1J2EE技术................................................................................................72.1.1J2EE技术特点与逻辑体系结构.......................................................72.1.2J2EE组件技术...................................................................................82.1.3J2EE模式..........................................................................................92.2MVC模式.........................
