智能制造——数字化工厂
从智能工厂到智能生产，数字化工厂的层次分析及应用案例全球产业价值分配附加值微笑曲线价值链技术与资本密集劳动密集信息与管理密集全球产业价值链The Third Industrial Revolution第三次工业革命当前,第三次革命正在展开,这就是制造业的数字化。制造业数F i字化为传统制造业的面貌和生产方式正在带来巨大改变Bret Ryder我们传统的工厂是从设计到开模生产,需要投入大量设备、资金和人力,如今有了三维印制机,只要在电脑上设计,就可三维打印出零部件和产品,包括航空航天、汽车摩托车、各种装备等复杂产品的精密零件及各种生活和工业用品,这种新型工艺的应用具有无限可能,并可大幅降低制造的门槛。计算机软件、新型材料、更灵活的机器、新工艺(特别是三维打印),以及网络上提供的各种软体服务,这些新科技的汇聚使工厂将逐渐告别大批量生产,进入完全客户化定制,以更低的成本、更高的效率和质量生产更多样化的产品,满足不同顾客的不同需求。所有革命都要进行一场惨烈的淘汰,不会以人的意志为转移。第三波工业革命,×也不例外,就像之前两波工业革命都曾淘汰若干行业和劳工,未来制造业势必再出现一场优胜劣败的大洗牌,工厂需要的劳工将越来越少,但需要更高的技能。当工厂需要的劳工减少,工资占生产成本的比重也会降低,从而改变目前到工资低的海外国家设厂的模式,跨国企业将逐渐把工厂搬回国内,以便设计人员能够和生产线更密切合作,同时更能贴近客户并迅速回应其需求。先进发达国家的应对策略2009年1月,美国邛BM公司提出了“智慧地球( Smarter planet)"概念。2009年4月,新西兰政府推出了《新西兰数字战略2.0》>2009年6月,英国出台了“数字英国( Digital Britain)”战略。>2009年7月,日本推出了《- Japan战略2015》>2009年9月,韩国出台了红IT韩国未来战暗》研究。>2010年5月,欧盟推出了《信息化战略行动计划》以应对当前欧盟的金融危机。2010年,奥巴马政府签署规模为170亿美元的《美国制造业促进法案》;2011年6月,又启动了美国《先进制造伙伴》计划2011年4月,德国首次提出了《工业4.0》发展战略,旨在支持工业领域新一代革命性技术的研发与创新,提高德国工业的综合竟争力T。 ra smarte冒aetimtlememtays she.OrSIRIRTA欧盟“信息化战略行动计划”欧盟“信息化战略行动计划”是欧洲数字计划七项旗舰举措中的一项,可促进经济的明显增长,使社会各领域都能享受数字时代带来的快捷和便利。增强数字化文化技能应用信息和通信技术应对和包容性气候变化和人口老龄化信息化战略行动计划七大领域更强的互操作性更多的研发投资增强互联网的信任度更快的互联网接入和安全性统一数字市场的建立美国“先进制造伙伴”计划为了巩固制造业竞争优势并确保其在世界制造强囯中的领先地位,美囯提出并启动了“先进制造伙伴( Advanced Manufactur ing Partner ship)”计划,并投入5亿美元推动这项工作。主题词:3D打印、物联网、制造回归、先进材料、新一代机器人、自动化生产线、节能制造工艺2029年1月人工奥巴马发表美写2013年2月济要让已2014年8月奥巴马国智魘唱长机出工出台《造德驾台支提发动唱长的声明量促进作仅悍计见印素重振美国制告业211年月21年】月选力公室出台【美国奥已马提出键出台《想新战:设全美想遇业3D打印机圈人美西皇保护我们为出胃络针复呢》是济增长机将打情咤需】为方之工业4.0—一从智慧工厂到智能生产信息物联系统a Industry 4.0德国高科技战略计划首位电子、IT、工复杂程业机器人工业革命4度电力广泛应用工业革命30工业革命20茶汽机1784工业革命1018世纪末20世纪初时间工业4.0——从智慧工厂到智能生产a Industry 4.0国高科技战略计划首位“工业4.0”研究项目由德国联邦教硏部与联邦经济技术部联手资助,在德国工程院、弗劳恩霍夫协会、西门子公司等德国学术界和产业界的建议和推动下形成,并已上升为国家级战略。德国联邦政府投入达2亿欧元运 Fraunhoferi acatechNATIONAL ACADEMY OFSCIENCE AND ENGINEERINGSIEMIENS
