Research On Product Structure Management And Its Correlation Technologies In Product Data Management System

This dissertation is based on the project "Shanxi Jingwei Textile Machinery Co.LTD Product Structure Management System",which is developed by CAD research lab at the Institute of Zhejiang University process control department. Product Structure Management is the core of Product Data Management system and is necessary and important to manufacturing information Engineering.This dissertation focusing on Product Structure Management gives a particular expatiation of PSM's conception, develop method and correlative technology.The main content of the dissertation is present as follows:1. Analyses the importance of PDM's applicaton in the manufacturing field based on large survey. Expatiates on the PDM definition and its status in quo. Meanwhile, discusses the key status of PSM in the structure of PDM and summarizes several essential steps which should be done before separate the PSM system as software from PDM system.2. Clarifies PSM, version control and configuration management concepts in detail and summatrizes the key technologies used in PSM system realization.3. According to the current status of database thechnology and the Jingwei Textile Machinery Co.LTD's practice status studied out database plan, Introduces an effective method of compiling materiel coding.4. Proposes a new method in PowerBuilder through its treeview and datawindow controls based on accomplished materiel coding and established database. This method could automatically establish product structure tree and produce BOM table in required format.5. Famous integration software I-DEAS has advanced Team Data Management system, this paper detailedly introduces the TDM system's work mode which has rich reference value.6. The I-DEAS' secondary development technology is described in details in this article including how to realize the integration of PSM and I-DEAS and how to realize the I-DEAS interface's secondary development, etc.7. Dissertates PDM (include PSM) system implementation conception and method. At last this paper gives a detailed report of the whole PSM system develop process including establishing product structure tree;BOM data-base ;automatically producing BOM table in required format; transforming and producing various BOM views such as Borrowing Part Table and Standard Part Table, also realizing parts numbers' automatical label and modification,etc.
