1，找一個/一類熟悉的產品，刻意去分析有關產品生命周期的產品開發，用戶使用情況，價格，銷量，外部市場變化等，通過改變橫縱坐標參數，畫出多種圖形。
答；DVD的生命周期
2.閱讀一篇以上Product Life Cycle相關英文文章，要求用英文摘錄文章主旨，并列出關鍵單詞等，還須附上文章鏈接
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 toFran?ois 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.
現在被稱為PLM的商業流程的靈感來自于美國汽車公司(AMC)。[4][5]據負責產品工程與開發的副總裁弗朗索瓦?卡斯特(Francois Castaing)說，該公司正在尋找一種加速其產品開發過程的方法，以便在1985年與更大的競爭對手競爭。[6]缺乏“大規模預算的通用汽車(General Motors)、福特,和外國競爭對手…AMC研發強調加強產品生命周期的主要產品(特別是吉普車)。[7]在引進了其緊湊的Jeep Cherokee(XJ)之后，該公司推出了現代運動型多功能車(SUV)市場，并開始開發一種新的車型，后來成為吉普大切諾基(Jeep Grand Cherokee)。第一部分對快速產品開發的追求是計算機輔助設計(CAD)軟件系統，使工程師更有效率。[6]這一努力的第二部分是新的通信系統，使沖突得以更快地解決，同時減少了昂貴的工程變更，因為所有的圖紙和文件都在中央數據庫中。[6]產品數據管理非常有效，在AMC被克萊斯勒收購后，該系統在整個企業中不斷擴大，使所有參與設計和制造產品的人都參與其中。[6]作為PLM技術的早期采用者，克萊斯勒能夠成為汽車行業最低成本的生產商，在上世紀90年代中期，它的開發成本占行業平均水平的一半。[6]
在1982 - 83年，羅克韋爾國際公司開發了b - 1b轟炸機的PDM和PLM的初始概念。[8]該系統被稱為工程數據系統(EDS)，它與計算機視覺和CADAM系統相結合，以跟蹤部件和組件的部件配置和生命周期。隨后，Computervison只發布了PDM方面的實現，因為生命周期模型是針對Rockwell和航空航天需求的。
