And approximately one hundred manufacturing enterprises have implemented projects of cims , such as pdm ( product data management ) and erp ( enterprise resource plan ) etc . , and have got remarkable benefit 目前,我国己有数以千计的企业实施了cad / cam , mrpii等单元技术,近百家制造企业实施了cims工程,如pdm (产品数据管理)和erp (企业资源计划)等系统,并已取得了显著的经济效益。
As an integration platform , pdm ( product data management ) goes through three stages : the earlier simple pdm systems cooperating the using of cad tools , the professional pdm products and the new generation pdm products - collaborative product commerce ( cpc ) 产品数据管理( pdm )作为集成平台，其发展经历了三个阶段：配合cad工具使用的早期简单的pdm系统、专业的pdm产品和新一代pdm产品? ?产品协同商务( cpc ) 。
However , in the progress of a enterprise ' s information technology application it is not always plain sailing . the problem will come forth ceaselessly . pdm ( product data management ) has been soundless naissance when people are taking delight in talking cadvcam 但是，企业在信息化的过程中并不是一帆风顺的；新的问题会不断出现，当人们还对在cad cam津津乐道之时， pdm ( productdatamanagement )已悄然诞生。
Pdm ( product data management ) is a tool that helps engineers and others manage both data and the product development process , pdm system keep track of the masses of data and information required to design , manufacture , and then support and maintain products Pdm ( productdatamanagement )是工程设计人员及其它人员用于管理产品数据和产品开发过程的工具， pdm主要管理的内容是在产品设计、制造及支持维护中出现的大量数据和信息。
Pdm ( product data management ) is a techology to manage product - related information and processes throughout the lifecycle of product . it is not only the efficient way to improve the level of multi - area product developing management during the latest period , and the essential element of information integration for enterprise , but also the foundation for implementing the distributed , integrated , professional enterprise and for forming the new organization style such as multi - area manufacturaion , dynamic union , visual enterprise Pdm (产品数据管理)是一种管理产品整个生命周期内所有与其相关信息和过程的技术，是新时期下提高跨地域企业产品开发管理水平的有效手段，是实现企业信息集成的关键，是企业向分布化、集团化和专业化，以及异地制造、动态联盟、虚拟企业等新的企业组织和合作方式发展的基础。
Pdm ( product data management ) , which is 3c ( cad / capp / cam ) application integration frame , can make up the insufficiency of traditional capp which is document manager , workflow manager and user manager , and so on , can be propitious to capp develop to integration , tool , utility in environment of enterprise information and in favor of information share Pdm作为capp系统的集成框架，能够弥补传统capp系统在文档管理、流程管理、用户权限管理等方面的不足，有利于capp系统在整个企业信息化环境下向集成化、工具化、实用化的方向发展，有利于企业信息系统的共享。
The process management method integrating project management and workflow management has been put forward , and the implementing mechanism has been analyzed . furthermore , its effective has been proved by applying it to helicopter ' s fuselage design . on the basic of pdm ( product data management ) , the implementing mechanism has been analyzed from the control manner and status graph management perspectives 提出了项目管理与工作流管理集成的过程管理方法，深入分析了基于项目管理进行工作流管理的实施机制，实现了基于项目管理的工作流管理方法在直升机设计中的应用，并在pdm基础上，从工作流执行的控制方式和状态管理上分析了过程管理的实施机制。
Iii ) according with distributed pdm ( product data management ) , the paper brings forward whole structure and function module partition of based on web garment structure graphics design subsystem , iv ) making use of web db technology , three layer b / s implement technology , asp , teledb accessing component ado and other technology realize web db long - distance accession , storage and safety transmission of garment structure graphics and relative data , intercourse of professional information , project management and garment graphics cooperative design ( 3 )以分布式产品数据管理理论( pdm )为依据，提出了基于web的服装结构图形设计子系统的整体结构及功能模块划分。 ( 4 )运用web数据库技术、三层b / s实施技术、 asp技术及其远程数据库访问组件ado等技术，实现了基于web技术的网络数据库远程访问，服装结构图形文件及相关信息的存储、图形数据传输安全，专业信息交流，项目管理，并实现了服装图形协同设计。
By adopting the viewpoint of jialing tool & mould alone manufacturing island ( ami ) in the thesis , it first analyzes the actuality of tool mould system in jialing group equipment and project company , and the development of domestic and overseas manufacturing advanced technology innovating . secondly , it consider establishing jialing - alone manufacturing island of tool & mould ( jl - amitm ) as a hardcore , with applying virtual cad / cam / cae system , rapid prototyping manufacturing ( rpm ) and capp ( computer aid process planning ) system on pdm ( product data management ) basis , to found the quality control system of a spot products , and to form a new manufacturing mode with variety and small quantity 本文应用独立制造岛技术观点，首先分析了嘉陵集团设备工程公司的工模具系统的现状和国内外先进制造技术的发展方向，接着考虑以建立以嘉陵工模具独立制造岛为核心，采用虚拟cad / cam / cae系统，应用快速原型制造技术，实施基于pdm的并行集成化capp系统，建立工模具制造质量控制系统，从而形成一种多品种、小批量的新型生产模式。
