Study & Application On Product Structure Definition And Configuration Management For Product Design

As the result of increasing market competition and rapid change of customer's requirements, manufacturing enterprises, especially those which develop and produce large and complex products, promote new requirements against product structure definition and configuration management. Practically product structure definition and configuration management under 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 production structure definition and configuration management to improve PDM systems' applicability, which is expected to offer a solution for vast problems in information management upon enterprise product design.This thesis firstly explains the connotation of product structure definition and configuration management on relevant theory's basis. A product structure information integration model is then built up over analysis on product structure definition and configuration process. This model tends to secure the effective management of product structure definition and configuration process and relative diverse information from the theoretical point of view. Secondly the thesis centers around this product structure information integration model and works further over product structure definition and configuration management in PDM. Theory and method of this management portion are discussed respectively with production structure management, configuration management and assembly-powered tiered process management and are applied to describe the implementation process of product structure definition and configuration management. The transforming mode from designing to manufacturing stage in product structure definition and configuration management is also dissertated. Thirdly the thesis puts forward a PDM architecture that supports product structure definition and configuration management from the angle of software implementing. Technology of Internet, database, security, object-orientation and configuration management are generally included as this architecture's supporting technologies. This thesis primarily makes a thorough study of product structure description methods with their advantages and disadvantages, data structure constructing forms and arithmetic that realize theseforms, which in a whole help to implement above-defined product structure definition and configuration management.Lastly the thesis comes back to enterprise's practical requirements in product structure definition and configuration management. Taking a PDM List Management System of one automobile engineering academy for example, it specifically introduces the implementation of this PDM system which holds product structure definition and configuration management for the core function. Correctness and practicability of former-dissertated architecture and method and technology are consequently justified with the example system's excellent practice and effects.
