幻灯片1Lean Thinking and Lean Manufacturing System 精益思维和精益生产系统Starting with Toyota in the late 50’s and catching on in the mid – 80’s in the reminder of the industrial world, Lean Manufacturing has become a key strategy for manufacturers起源于20世纪50年代丰田汽车公司,而在80年代中期被欧美企业纷纷采用。
随着微利时代的来临,精益生产模式成为企业竞争的有力武器幻灯片2Marketing Competition and Globalization市场竞争及全球化●Shorter lead time and on time delivery●快速并准时交货●Grow the mix,special configurations●需求品种增加,特殊定制●Maintain / improve quality and reduce price●不断改进质量及降低销售价格●Total life cycle of product becoming shorter and shorter ●产品的生命周期越来越短●No boundary,business globalize village●无国界,业务“地球村”●幻灯片3Marketing Competition and Globalization市场竞争及全球化幻灯片4Lean Thinking and Lean Manufacturing System 精益思维和精益生产系统The are two ways to think about the relationship of Price, Cost and Profit在价格,成本和利润的关系中,有两种不同的思考方法:1。
传统的方法销售价格 = 成本 + 利润2。
