Development On Isomerism PDM System Based On The Web

As the result of increasing market competition and rapid change of customer's requirements, manufacturing enterprises especially those, develop and produce large and complex products, promote new requirements against product structure management. Practically product structure management base on PDM architecture is one absolutely necessary core function of enterprise e-manufacturing supporting platform. This thesis therefore steps from the requirements of enterprise product design management and focus on studies on theory, method and implementation technology of product structure management improve PDM systems'applicability, which is expected to offer a solution for vast problems in information management upon enterprise product design. PDM is a new idea and technology of management. PDM can be defined that it is based on software technology and cored with product which can fulfill integration management to the data that associate to product include data, process and resource.This article has expounded the definition of PDM (product data management), development, system framework and function. It has discussed that the status of PDM in an enterprise and the application status of PDM. The paper gives a detailed introduction of how the product structure tree is established, product configuration management, data enquiry, data sharing, security and secrecy and the management of users'operation rights.Based on above research, the paper has given an example of"Applied Product Data Management System"which is Taiyuan risk investment item. The important model of PDM is the model of product structure management and the model of product configure management. They have been researched deeply in this article. The connection between each sort of data object associating with the product data and product configure has been analyzed. The bases of technology and thinking of the foundation of product structure tree has been expounded. The fulfilling method has been given.Finally, this paper makes a prospect of the development of PDM technology. With the demand of constant development and new requirements of enterprises for the new technology, PDM products will tend to be more humanized, suitable, operative and scientific.
