产品数据管理( PRODUCT DATA MANAGEM ENT, P D M)技术是90 年代的新技术,它为 C A D/ C A M 集成和 C I M S、并行工程的实施提供了一个框架.该文论述了 P D M 的研究意义和内容,提出了 P D M 的体系结构,指出了关键技术及其解决途径.“,”Conditions in PRC differ widely from those in developed countries. So PDM in China needs very careful selection of its key techniques to be included in a framework effective for integration of CAD/CAM and implementation of CIMS and concurrent engineering. The key techniques that we deem should be included consist of: (1) integrated product information model, (2) product database, (3) the structure, control and management of product data, (4) workflow management, (5) CSCW (Computer Supported Cooperative Work), (6) integrated function model and other support tools. A framework of PDM is developed. The framework uses a graphical user interface for communication purposes. The interface, shown in Fig.2, includes four divisions: (A) organization management view, (B) resource and application tool management view, (C) product configuration management view, and (D) process management view. These four divisions control seven functions: (E) digital database, (F) organization management model, (G) equipment data model, (H) application tool management model, (I) workflow and process model, (J) product configuration management model, and (K) data exchange standard interface. The effectiveness of this framework is yet to be tested in a certain CIMS project.
