Document Management Model of Vehicle Concurrent Design Based on PDM Enablers

There is no standard interface among traditional PDM systems,hence,for lack of intercommunion,it is difficult to join them with international systems.Therefore,the mutual exchange of procuct data is restricted in vehicle concurrent design.PDM Enablers specification,issued by Object Management Group(OMG),sustains distributed environment of product data management,and provides standard interface for various PDM systems.Thus,the problems above mentioned could be solved beautifully.The paper refers to PDM Enablers specification and adopts the object-oriented modeling method.At first the architecture for concurrent engineering environment is presented based on Enablers.Then document management model is illustrated based on Enablers,and changeable states of document and mechanism of version management are researched emphatically.Finally the information storage mode of document management for supporting the vehicle concurrent design is discussed.
