PDM 以软件为基础 是一门管理所有与产品相关的信息 包括电子文档 数字化文件 数据库记录等 和所有与产品相关的过程 包括工作流程和更改流程 的技术 它提供产 品全生命周期的信息管理 并可在企业范围内为产品设计和制造建立一个并行化的协作环 境 PDM 的基本原理是 在逻辑上将各个 CAX 信息化孤岛集成起来 利用计算机系统控 制整个产品的开发设计过程 通过逐步建立虚拟的产品模型 最终形成完整的产品描述 生产过程描述以及生产过程控制数据 技术信息系统和管理信息系统的有机集成 构成了 支持整个产品形成过程的信息系统 同时也建立了 CIMS 的技术基础 通过建立虚拟的产 品模型 PDM 系统可以有效 实时 完整的控制从产品规划到产品报废处理的整个产品生 命周期中的各种复杂的数字化信息 产品数据管理 PDM ProductDataManagement 技术 很难有一个准确的定义加以描述 但就现阶段 PDM 的发展情况而言 可以给出一个较为 具体的定义 PDM 技术以软件技术为基础 是一门管理所有与产品相关的信息 包括电 子文档 数字化文档数据库记录等 和所有与产品相关的过程 包括审批 发放 工程更改 一般流程 配置管理等 的技术 提供产品全生命周期的信息管理 并可以在企业范围内 为产品设计与制造建立一个并行化的协作环境 凡是最终可以转换成计算机描述和存储的数据 PDM 都可以一概管之 例如 产品结 构和配置 零件定义及设计数据 CAD 绘图文件 工程分析及验证数据 制造计划及规范 NC 编程文件 图像文件 照片 造型图 扫描图等 产品说明书 软件产品 程序 库 函数等 零部件 各种电子报表 成本核算 产品注释等 项目规划书 多媒体音像产 品 硬拷贝文件 其它电子数据等 由此看来 所谓 PDM 并不只是一个技术模型 也不是一堆时髦的技术辞藻的堆砌 更不是简单的编写程序 它必须是一种可以实现的技术 必须是一种可以在不同行业 不 同企业中实现的技术 必须是一种与企业文化相结合的技术 因此 它与企业自身密切相 关 考察当今 PDM 实施成功的企业 每个企业都有自己非常具体的奋斗目标和项目名称 从福特的 Ford2000 波音的 DCAC MRM 到日产的 业务过程革新 等 凡取得成就者 无一不是将 PDM 融汇于企业文化之中 因此 PDM 的生命力 或换而言之 PDM 之精髓 也正在于此 PDM 的发展过程可以概括为以下三个阶段 1 配合 CAD 工具的 PDM 系统早期的 PDM 产品诞生于 20 世纪 80 年代初 2 专业 PDM 系统通过对早期 PDM 产品功能的不断扩展 最终出现了专业化的 PDM 产品 如 SDRC 公司的 Metaphase 和 UGS 的 iMAN 等就是第二代 PDM 产品的代表 3 PDM 的标准化阶段 1997 年 2 月 OMG 组织公布了其 PDMEnabler 标准草案 在 20 世纪的 60 70 年代 企业在其设计和生产过程中开始使用 CAD CAM 等技术 新技术的应用在促进生产力发展的同时也带来了新的挑战 产品数据管理 Product Data Management 简称 PDM 正是在这一背景下运行而生的一项新的管理思想和技术 PDM 明 确定位为面向制造企业 以产品为管理的核心 以数据 过程和资源为管理信息的三大 要素 PDM 进行信息管理的两条主线是静态的产品结构和动态的产品设计流程 所有 的信息组织和资源管理都是围绕产品设计展开的 这也是PDM 系统有别于其它的信 息管理系统 如 MIS 制造资源计划 MRP 项目管理系统 PM 企业资源计划 ERP 的关键所在 近几年来 我国不少企业不断深入地应用计算机技术 PDM 也在企业中引起了重视 不少企业对 PDM 技术产生了兴趣 产品数据管理 PDM 在实现企业的信息集成 提高 企业的管理水平及产品开发效率等方面的意义是十分巨大的 我国许多大中型企业都已充 分认识到了这一点 但目前国内 PDM 的应用还比较薄弱 因此 探索 PDM 实施的成功经 验和实施的方法学 对推进 PDM 的应用具有很重要的意义 产品数据管理系统 PDM 是企 业设计和工艺部门的基础数据平台 但现在 PDM 的应用早已超出了工程设计领域 今天 越来越多的公司已经或正在准备安装 PDM 系统 经过近些年来的发展 PDM 技术已经取得了长足进步 在机械 电子 航空 航天等 领域获得了普遍的应用 PDM 技术正逐渐成为支持企业过程重组 BPR 实施并行工程 CE CLMS 工程和 SIO9000 质量认证等系统工程的使能技术 目前 国产 PDM 产品的在企业中的应用主要包括以下几方面 1 企业产品数据的归档 2 企业使用统一编码 3 企业产品结构的管理 4 技术部门的过程管理 5 企业产品数据的处理 6 工程和生产领域集成 7 企业工程信息的提取 随着计算机应用的迅速发展 采用计算机辅助设计技术和先进的信息管理技术是企业 进行技术更新改造 提高产品竞争力的必由之路 PDM 技术开发的方向会集中在以下三个 方面 电子商务和合作商务 虚拟产品开发和支持供应链管理 据国外资料统计 PDM 的 应用能使产品设计过程缩短 25 减少工程设计修改 4 加快产品投放市场进度 50 80 总成本削减 25 以上 国外的一些汽车 飞机公司实施 PDM 系统后的均大大提高 了企业的效益 随着中国信息化进和的发展 国内应用 PDM 系统的企业也越来越多 PDM 产口的开 发与应用进入了快速发展的时期 目前 尽管国产 PDM 产品在功能 性能及稳定性方面 与国外软件还有差距 但在适应企业需求 价格及技术支持等方面已经具有了一定的优势 相信随着国内 PDM 产生厂家的不断努力国产 PDM 产品会有更加美好的发展前景 PDM is based on software is a management of all product related information including electronic documents digital files database records etc and all product related processes including work processes and change processes technology It provides information on product life cycle management and it can design and manufacture for the products to establish a parallel environment in business activities PDM s basic principle is that each CAX logically integrate islands of information and it uses computer systems to control the entire product development process through the gradual establishment of a virtual product model and ultimately form a complete product description description of the production process and production process control data The organic integration of technical information systems and management information systems forms the entire product to support the formation of information systems but also to establish the technical basis of the CIMS Through the establishment of a virtual product model PDM systems can be effective real time complete control of products from product planning to scrap the entire product life cycle of complex digital information Product Data Management PDM ProductDataManagement technology is difficult to have a precise definition to describe However at this step of development of the PDM you can give a more specific definition PDM technology is based on software technology is a management of all product related information including electronic documents digital documents database records etc and all product related processes including the approval issuance engineering changes the general process configuration management etc technology It provides information management of product life cycle and can design and manufacture for the products to establish a parallel environment Eventually it can be converted to describe and store data PDM can manage it such as product structure and configuration the part definition and design data CAD drawing files engineering data analysis and validation manufacturing plans and specifications NC programming file image files photos modeling diagrams scan etc product specifications software programs libraries functions and other parts a variety of electronic reporting cost accounting product notes etc project plan and multimedia audio and video products hard copy documents and other electronic data From this the so called PDM not just a technical model nor is it a bunch of trendy concoction of technical rhetoric more than a simple programming It must be a technology can be achived must be a in different industries and different companies technology can be achieved must be combinated with the business culture Therefore it is closely related to the business Examine the implementation of PDM in successful business nowadays each enterprise has its own very specific goals and project name from Ford s Ford2000 Boeing s DCAC MRM to Nissan s business process innovation and so on the achievers use the PDM to blend of business culture Therefore PDM vitality in other words PDM essence is also here PDM development can be summarized as the following three stages Firstly PDM system with CAD tools PDM product was born in the early 20th century 80s Secondly professional PDM system by early PDM product capabilities continues to expand culminating in the PDM specialized products such as SDRC s Metaphase and UGS iMAN so that the second generation of PDM product representatives Thirdly standardization phase of PDM in February 1997 OMG standards organization announced its In the 20th century of 60 70s the enterprise in its design and production process to start using CAD CAM and other technology new technology applications in the development of productive forces it also brings new challenges Product Data Management Product Data Management referred to as PDM It is in this context that run a new management ideas and techniques PDM clearly positioned the core for manufacturing product management the management information of the three elements is data processes and resources The two main lines of PDM processing information management are static and dynamic product structure product design process all the information organization and resource management are carried out around product design which is the PDM system is different from other information management systems such as MIS manufacturing resource planning MRP project Management PM enterprise resource planning ERP is the key In recent years many companies in China continue to in depth application of computer technology PDM also attracted attention in the enterprise many companies became interested in the PDM technology Product data management PDM play an significant role in the business information integration improve the management level and efficiency in product development many of our large and medium enterprises are fully aware of this but the domestic application of PDM is still relatively weak therefore to explore the successful experience of PDM implementation methodology and implementation for promoting the application of PDM has very important significance PDM product data management system is the platform of design and technology department but the PDM applications beyond the engineering industrials Today more and more companies have or are installing the PDM system After recent years of development PDM technology has made great progress and to obtain a universal application in machinery electronics aviation aerospace and other fields PDM technology are becoming an enabling technology to support the business process reengineering BPR the implementation of concurrent engineering CE CLMS SIO9000 quality engineering and systems engineering certification At present domestic PDM products in the enterprise applications include the following aspects 1 Enterprise product data file 2 business use Unicode 3 the management of product mix 4 process management of technology sector 5 Enterprise product data processing 6 integration of engineering and production 7 Enterprise engineering information extraction With the rapid development of computer applications the use of computer aided design technology and advanced information management technology is the way to technical renovation and improve product competitiveness PDM technology development direction focus on three are
