答；DVD的生命周期
2.阅读一篇以上Product Life Cycle相关英文文章，要求用英文摘录文章主旨，并列出关键单词等，还须附上文章链接
The inspiration for the burgeoning business process now known as PLM came fromAmerican Motors Corporation(AMC).[4][5]The automaker was looking for a way to speed up its product development process to compete better against its larger competitors in 1985, according toFrançois Castaing, Vice President for Product Engineering and Development.[6]Lacking the "massive budgets of General Motors, Ford, and foreign competitors … AMC placed R&D emphasis on bolstering the product life cycle of its prime products (particularly Jeeps)."[7]After introducing its compactJeep Cherokee (XJ), the vehicle that launched the modernsport utility vehicle(SUV) market, AMC began development of a new model, that later came out as theJeep Grand Cherokee. The first part in its quest for faster product development wascomputer-aided design(CAD) software system that make engineers more productive.[6]The second part in this effort was the new communication system that allowed conflicts to be resolved faster, as well as reducing costly engineering changes because all drawings and documents were in a central database.[6]The product data management was so effective that after AMC was purchased by Chrysler, the system was expanded throughout the enterprise connecting everyone involved in designing and building products.[6]While anearly adopterof PLM technology, Chrysler was able to become the auto industry's lowest-cost producer, recording development costs that were half of the industry average by the mid-1990s.[6]
During 1982-83, Rockwell International developed initial concepts of PDM and PLM for the B-1B bomber program.[8]The system called Engineering Data System (EDS) was augmented to interface with Computervision and CADAM systems to track part configurations and lifecycle of components and assemblies. Computervison later released implementing only the PDM aspects as the lifecycle model was specific to Rockwell and aerospace needs.
现在被称为PLM的商业流程的灵感来自于美国汽车公司(AMC)。[4][5]据负责产品工程与开发的副总裁弗朗索瓦•卡斯特(Francois Castaing)说，该公司正在寻找一种加速其产品开发过程的方法，以便在1985年与更大的竞争对手竞争。[6]缺乏“大规模预算的通用汽车(General Motors)、福特,和外国竞争对手…AMC研发强调加强产品生命周期的主要产品(特别是吉普车)。[7]在引进了其紧凑的Jeep Cherokee(XJ)之后，该公司推出了现代运动型多功能车(SUV)市场，并开始开发一种新的车型，后来成为吉普大切诺基(Jeep Grand Cherokee)。第一部分对快速产品开发的追求是计算机辅助设计(CAD)软件系统，使工程师更有效率。[6]这一努力的第二部分是新的通信系统，使冲突得以更快地解决，同时减少了昂贵的工程变更，因为所有的图纸和文件都在中央数据库中。[6]产品数据管理非常有效，在AMC被克莱斯勒收购后，该系统在整个企业中不断扩大，使所有参与设计和制造产品的人都参与其中。[6]作为PLM技术的早期采用者，克莱斯勒能够成为汽车行业最低成本的生产商，在上世纪90年代中期，它的开发成本占行业平均水平的一半。[6]
在1982 - 83年，罗克韦尔国际公司开发了b - 1b轰炸机的PDM和PLM的初始概念。[8]该系统被称为工程数据系统(EDS)，它与计算机视觉和CADAM系统相结合，以跟踪部件和组件的部件配置和生命周期。随后，Computervison只发布了PDM方面的实现，因为生命周期模型是针对Rockwell和航空航天需求的。
