    未知因素

    2018-08-23T15:09:45Z

    通用费尔法克斯除了原有的Chevy Malibu轿车之外,又在全力以赴制造新款Cadillac XT4。Gareth Price去了堪萨斯城,与厂长Bill Kulhanek谈论新纪元的发展你们为新工艺做了哪些准备呢?生产线上工程制造有变化吗?两款汽车 —Cadillac XT4和Chevrolet Malibu — 正好共用整体结构。因此,我们要做的就是增加机床作业,接收不同的车型。当你经过汽车车体修理厂的时候就能看到,不同的工作站使用不同的托盘,用于处理特殊车型作业。 Bill Kulhanek, GM Fairfax plant manager因此,对Malibu来说就是选好一个地方,而对XT4来说就得选择另一个地方。它们可以移动,或者我们的托盘是特定车型的,我们只是按照要求摆放。未来蓝图里,根据目前Malibu产量的情况下,你们是要全力提高Cadillac的产量吗,还是销量会逐步提呢?我们是8月末推出Cadillac汽车的,一个半月之后Cadillac的生产力将达到最高,而且这会只持续到年底。Cadillac的销量证明两件事。第一件是,我们都知道轿车的销量不断下降,因此Malibu的补充生产也就换下来了。此外,这也给了我们一个机会,如果需要的话,我们就可以额外生产。对通用汽车来说,XT4是一款崭新的跨界车,也是新的车段。因为我们在跨界车市场里没有极具竞争力的汽车。XT4是怎么走到今天的,Cadillac呢?你们工厂是把这件事当做生意来做的吗?通用汽车考虑了很多因素。什么环节的成本效益最高?工厂从指标角度上要怎么做?产品拿到工厂投产要多少成本?物流成本。有一大堆的因素要考虑进去。我们有一个积分卡,记录不同的指标。积分卡的记录越好,工厂就越好,你就越能证明一个产品为什么要放在这个特定的车间。工业4.0通常指的是什么,是用数据推动工艺提高效率,还是改变流程? — 你们处理数据来源的经验是什么?知道哪些零部件是哪个车上的,我们这方面的技术非常好。而在过去的四五年里,我们这方面可能又加强了。因此,如果有一个发动机零部件运到我们这里,要安装到一辆车上,我们就知道这是哪款汽车。因此我们传输汽车信息的方面做得很好。从停工方面来看,我们通过PLC(可编程控制器)数据报告,记录停工的时间和恢复的时间。所以我们对维护和产品两方面都有记录。 费尔法克斯合理处理了新款跨界车与原有Chevrolet轿车装配之间的平衡当机器传递信息的时候,就会有人向你反馈。那么知识共享的流程是什么?这需要通用汽车两方面的问题。我们称其为“全球制造系统”。在这个系统里,人员金字塔充满了积极性。这样就形成我们称之为“业务计划发展”的模式,而且有不同的级别。员工是第一级,但是在团队成员界别上,就是五级。因此团队每天都要与集团领导见面,审核各项指标,然后再讨论刚说过的东西。现在我们有问题,我们认为可以改进。因为总体上讲,所有的事情都建立在真正的标准化工作至上。所以团队成员不断地审查他们的标准化工作,看看是否跟上了,是不是恰当的表转化?他们可以对标准化工作做些改动,提高安全性、质量和效率。因为这些是我们工作的根本所在。回想汽车车体修理厂,你说过Malibu和XT4公用一个平台。那在粘合、焊接及铆接过程中会有变化吗?其方法是相同的还是不同的?我们用在Malibu上的粘合方法就是粘合XT4的方法,因此从本质上讲,这就是焊接。但是有些是钎焊,而且我们大量使用粘合剂。我们没有多少铆接。我们使用一些螺栓,但是主要是在汽车车体修理厂以外使用。 GM Fairfax到堪萨斯城行车距离很短这些流程是不是达到很高的标准了呢?或者在境地能耗方面遇到一些困难,或者诸如此类的事情呢?是的,每年都如此。所以我们定下效率目标,这些是成本效率,但成本之一就是人力资源,还有一个是实用程序。因此,我们业务计划发展的一部分就是讨论如何降低公用设施费用,以及降低人力资源成本。你们有没有得到最佳时间理念的流程?通用汽车在北美,甚至欧洲和亚洲各姊妹工厂之间的关系如何?我们进行很多的谈话,不仅是我们北美地区,而是在全球范围。因此在我们汽车车体修理厂人力资源问题上,我们就从全球范围上研究所有的的汽车车体修理厂,以及全球最好的实践方案。然后我们才会说,那是特定车型生产中应该适用的汽车车体修理厂。然后我们希望所有的汽车车体修理厂都按照这种方式运营,从而最大限度提高效率。这就是人力资源角度上做事情。但是我们还有所谓的成本委员会,解决特定业务成本问题,其中之一就是公用设施费用。委员会代表来自个地区的工厂,因此我们可以互相学习,并拿出解决问题的最有效方案。会不会有竞争呢?我认为执行方面会有竞争,但不会出现在“我的方法和你不同,这种方法为我带来了好处”这种方面。我们共享理念做得很好。举另一个例子。我们有一个创新网站,因此如果我有一个创意可以优化Fairfax工厂,那么我就提交网站,然后全球所有工厂都会看到。因此我们不会藏着。我们拿出想法,我们的创意得到认可并分享。因此工厂根据提出创意的数量以及受惠工厂的数量而得到嘉奖。我认为从领导层面来看,这是很有帮助的。我认为我们的领导参观不同的工厂,看到这些工厂正在做些什么,在看到之后问到的一个问题就是,你们共享这个了吗?所以共享无处不在,人们对这件事已经有了共识。没有人保证我会在这里很长时间。我可以到其他的一个工厂。所有的事情放在一起,我们感觉到理念共享带来的友情,所有人都认真考虑执行下去。 准备工作包括Fairfax装配团队访问通用Warren工厂,该厂开发设计并制造了第一批XT4汽车着手转型费尔法克斯核心团队协调员Michael Poirier对AMS说,从重型轿车到小型跨界车的转型是一个大挑战。有个案调查显示,向费尔法克斯引进XT4是一件非常有趣的事情:这个车型要从轿车转型跨界车了。Poirier团队面临的挑战就是在实践中改变并安装部件;还有一些不需要设计师考虑的小细节。“我们不得不对我们的传输系统做些改动,同时对材料输送到生产线的方式进行改进,等等。”在准备阶段,Poirier和他的团队在密歇根通用涡轮中心工作,在这里设计XT4汽车,并开发第一批汽车。他们尽可能从车间学习,并找到能够协调目前Malibu装配厂流程的方法。“我们必须保证不会向装配流程加入多余的垃圾。我们从一开始就这么做了,而且我们迟早都会解决这个问题的。”还有一个有关天窗螺丝的例子。Poirier的团队发现,固定器的作用“仅仅是增加噪音,我们不需要它。”“这是在我们看到实物之前就搞定了的,这对我们以及工厂都有好处。”在后挡板上下功夫而不是后备箱,XT4车型的这个特点是否有难度,不同的零部件是否要放到不同的部位?Poirier证实说,“是的,而且其中的修饰成分要远多于制造过程。因此,在我们启动这款汽车的时候,我们就放弃输送器,转而使用自导车辆系统,用于车体与底座接合过程。通过这种方式,我们创造了自由空间,我们称之为32输送机。这种技术还用于汽车本身在输送器上接合的过程,然后在走流程。这样我们在32的末端还有空间,我们将其用于制造提升式门。这个还没有用于目前的汽车内,因为后备箱不需要制作成这个样子。”这个流程中,自动化和人工作业有什么变化吗? Poirier解释说,这个工作还是有人工完成的。那有没有自动化工艺,或者一些辅助设备呢?全部是手工处理,Piorier说:“比如说,他们还在现场安装挡流板。所有这些都是手工完成的。唯一需要辅助完成的(实际上就是一个定位器)就是后雨刷。这只是为了确保其位置正确。”在虚拟制造过程中,Piorier的团队是被并解决了100个问题,之后才会出品实际汽车。这些理念从滑板转变为实物并在生产线上生产,是一个极具吸引力的工作。填补这些空白证实Poirier和他的团队所擅长的。
