详细内容：LCP3000EZ 工业进化本质在提升质量，而非降低成本 　　人力成本被认为是导致近年制造业竞争力下降的原因，但李永利认为，制造业不能仅仅盯着制造环节的成本，应该更加注重供应链成本。而数字化制造从一开始就不仅仅是为了降低成本，最大的目的在于提升质量，而高质量并不意味高成本。 　　近年，国内制造业遭遇的发展瓶颈中，人力成本的上涨，被认为是导致制造业竞争力下降的重要原因之一。 　　“很多制造业的企业主都喜欢谈控制成本，但在西门子看来，质量才是企业的第一竞争力。”李永利反复强调，“质量第一”一直是西门子成都工厂战略目标首位，而这也是客户眼中最重要的价值。 　　事实上，在他看来，很多时候企业面临的并不仅仅是制造环节的成本，而应该更加注重供应链的成本。因为，即使在劳动密集型企业中，人力成本毕竟只是占据一定的比例，而不是成本的全部。 　　以一个简单的例子来看，当一款产品出厂时，它同时拥有了两个价值，一个是出厂价值，一个是到客户手中时的价值。“中国很多工厂生产出来的产品，出厂价值不高，但到客户手中的价值就很高，这就是供应链的问题。”李永利说道。 　　尽管他并不认可仅仅盯着成本来谈论“工业进化”，但李永利强调，数字化制造本身所带来的高质量并不代表是高成本。 　　高质量在工业制造领域的重要性不言而喻。作为耐用品的工业产品，比如一款海上风力发电机的产品，一旦出现问题，不仅造成的损失不可估量，而且需要动用到直升机维修，维修的后期成本也非常高。 　　为此，在实现质量提升上，数字化制造首先是借助自动化产线上的机器充当“纠错官”的角色，比如当工人少拧了一颗螺丝，机器会自动发出警示，阻止产品进入下一个环节，通过机器的协助，减少人的出错。 　　但在西门子看来，通过机器的“检查”杜绝人在制造过程的差错，这只是保证产品质量的基础一步，由制造质量、研发质量以及原材料质量组成的产品质量中，更需要的是借助数字化制造去保障研发质量和原材料质量。 　　尤其是如何保证原材料质量，一直被认为是制造业界最具挑战性的一个课题。 　　在SEWC的数字化制造中，一个很重要的方式是对原材料进行可溯源式的管理。也就说，在这座工厂内，当来自各地的原材料被运送到车间后，所有的原材料都拥有了自己的“身份证”。这个身份证可伴随原材料进入生产线，在每一个流程中，都会被相应的设备进行数据的采集和跟踪，并最终储存在后台的数据管理中。 　　这意味着，一旦有原材料的质量出现问题，工厂可以马上查找到这一批次的原材料在什么时间点，已经走过哪些生产流程。李永利表示，无论客户在今后什么时间反馈质量问题，工厂依旧能够拿出完整的数据，对这些原材料进行追溯，从而保证原材料的质量。 　　走向工业4.0，管理自动化才是关键 　　在数字化制造的阶段，通过数据交互，已经能够有效地提升管理效率。但要衡量是否真正走向工业4.0，不是看生产线自动化水平的高低，而是看管理水平的高低。实现管理的自动化，需要实现管理上人完全听命于“电脑”，这才是智能制造的未来。 　　事实上，这样一座代表着数字化技术如何改造工业制造的前沿工厂，距离工业4.0愿景下的智能工厂仍有距离。在工业4.0的研究中，智能制造和智能工厂一直被认定为两大研究主题。其中，关于智能工厂，被描绘成是一个分散的、具备一定智能化的生产设备，在实现了数据交互之后，形成了高度智能化的有机体，实现虚拟世界和物理世界的融合。 　　在SEWC中，关于推进数据交互的工作一直未曾停止过。但对于数字化工厂与智能化工厂之间的差距，李永利认为，最关键的一点在于是否真正实现管理的自动化。 　　西门子安贝格工厂 　　德国安贝格电子工厂作为西门子全球首个数字工厂，是SEWC的姐妹工厂。该工厂从1989年投产至今，占地面积与员工数量几乎都保持不变的情况下，产能却比25年前翻了8番。 　　无论是德国的安贝格电子工厂，还是SEWC，这两家工厂每年要生产几百万件产品，更考验管理的是，产品类别也达到了上千种。当涉及的产品类别众多，而且客户订单数量和周期不同，如何去做好订单管理，以及如何连通订单管理背后的生产制造、物流配送等多个环节，考验的正是管理的智能化水平。 　　相比普通工厂单凭人力做订单的跟踪管理以及后续生产的调度安排，SEWC的数字制造中，当ERP系统收到订单，MES系统将自动进行生产安排，包括通知采购部门、财务部门等，整个生产包括后期的发货全部由工具充当“指挥”，自动完成。 　　如果从劳动力的角度看，李永利认为，尽管在生产线上并不认可一味地以机器代替人，减少蓝领工人，但在管理“白领”群体时，在管理层面，他认为可以更多地借助机器，积极使用更多的软件。 　　“因为未来制造业的衡量标准不是生产线自动化水平的高低，而是管理水平的高低。”他认为，在中国制造实现智能化提升的路上，相比硬件设备，管理水平的高低才是影响中国企业能否实现工业4.0的关键。他强调，要真正实现工业4.0，一大标准是管理水平达到了一定的高度，甚至实现了自动化。 　　“如果管理实现自动化，也可以理解为，工厂的所有决策和指令都听命于电脑，连人也是听命于电脑。”李永利说道，但实现这一步显然并不容易，至少从理念上，如何让人完全听命于电脑，则需要一场思维变革。 　　但至少，数字工厂作为实现智能工厂的必经之路，已走出了第一步——让机器代替人去做更多的决策。而等到工厂内，真正能用自动化替代人进行管理，人听命于“电脑”的话，那么，电脑背后所代表的制造的未来，也将来到眼前。 Wavetek 131A VCG Generator Operating Service Manual Wavetek 135 Sweep Generator Operating Service Manual Wavetek Test and Measurement Inststrum. 1992 Catalog Wavetek 132 Noise Generator Operating Service Manual Wavetek 134 Sweep Generator Operating Service Manual Wavetek 145 Funct Generator Operating Service Manual 2 Wavetek HD-160 True RMS Digital Multimeters Wavetek 1983 Test & Measurement Instrumentatio​n Catalog Wavetek 1976 Catalog Wavetek Generation & Measurement Equipment Catalog Wavetek 1978 Generation & Measurement Equipment Catalog Wavetek DM73A Digital Multimeter Wavetek 142 VCG Generator Operating Service Manual Wavetek 110/111Generat​or Instruction Manual Wavetek JDSU CLI-1750 Cable Signal CATV Meter CLI1750 Wavetek JDSU CLI-1750 Cable Signal CATV Meter CLI1750 Wavetek JDSU CLI-1750 Cable Signal CATV Meter CLI1750 Wavetek 1038-V13 Operator/Servi​ce Manual *Original* SHIPS FREE!
