Research Of Product Configuration Management Based On AP239

With the broad applications of computer in the manufacturing industry, large numbers of information lacked of effective managed has come out. Those bring the difficults of reusing and finding information, so Product Dada Management (PDM) has come out. The PDM is the technology that it is using managing all the interrelated information of product (including parts information, configuration information, document, CAD files, authorize information and so on) and all the interrelated information of process. Product structure and configuration management is the most importance in PDM through all life cycle of product, taking charge organization and management product data. This paper focuses on research about the ways for the exchange and realize of product data and about building of product structure tree and configuration for the model of product structure and configuration management in product data management system based Shipbuilding STEP Application protocols AP239 (Application protocol 239,i.e. Product Life Cycle Support).This paper created a new thought for the data interface implementation from product data objects of the Application protocols AP239 to a large relation database. Here I take the advantage of SDAI, exchange data from one Application Protocol (AP) to large relation database, retrieve data and create a Product Database which conform to AP239.The data interface was implemented using ROSE tools and ROSE C++ lib provided by STEP Tools company. Database management system has most advantages than file management system. Database can meet the requirement of sharing product data on Internet in the future.Because the database is the very popular and best way to manage CAD system's data in current time,it can solve such questions as data redundancy, complex data structure and data share in naval architecture. So in this thesis. data was managed by common database management system and designed it. Content of the research work is realized to draw the product by CATIA software,to get step file,to get interrelated data about product assembly and to store those data to product database, and to built of product structure tree used VC++ software ,then configuration that tree based product configuration rules accord with the AP239 defined by users and requires.
