摘　　要：为了定性与定量描述产品在产品生命周期管理(PLM)设计阶段各环节信息状态,提出通过信息熵分析设计阶段各环节信息状态的不确定性,通过信息距离分析各环节取得某个状态所遇障碍的大小,然后采用顶层基本骨架(TBS)方法建立产品的三维模型并对其信息状态进行分析,结果表明,客户对产品的需求增加后,产品在设计及转移状态上需要的信息相应增加,通过信息状态的分析为产品在PLM设计阶段的开发过程提供信息学方面的依据。In order to qualitatively and quantitatively describe the state information of each link in Product Lifecycle Management （PLM） design phase, each link＇ s uncertainty of status information in design phase was analyzed by information entropy, the size of obstacles encountered in each link for reaching a certain state,which was analyzed by information distance. Then the three di- mensional model of product was established by TBS method and analyzed its state information, the results indicates that when the customer demand for product increases, the information of product in the design and transition status increases accordingly, this method provides the basis of informatics for the development of product in PLM design phase.
