Design of Experiments (DOE) 实验设计 (DOE);The objectives of this module are to allow the student to: 本单元的学习要点是： Understand the limitations of trial-and-error experiments. 明白反复实验的局限性 Appreciate the power of designed experiments. 感受实验设计的力量 ;What is Experimentation??? 什么是实验???;Read the case material provided and answer the following as teams: 阅读所提供的案例材料并分组回答下面问题： Based on a simple pmap for the curing process, what are the inputs? What is the desired output? What other questions might you ask about the process? ? 依据当前过程的简单过程图，输入是什么？期望的输出是什么？对这个过程你还会问哪些问题？ What value is the historical data – the fact that the best set point has been 155 degrees for 100 minutes for the old adhesive/hardener combination? How relevant is this information? ? 以往数据的产出率是多少，即老的硬化剂与粘接剂在155度烤100分钟的最佳设置时的实际状况？这个信息有多大用处? What questions might you have about the new experimental runs with the new hardener? ? 对新硬化剂运行的新实验，你会有什么问题？ Based on what’s known at the moment, would you suspect the supplier of the new hardener as the source of the degradation in yield? Why or why not? 就目前你所知道的信息，你认为导致产出率下跌的原因是新的硬化剂吗？为什么？ ;Read the case material provided and prepare the following as teams: 阅读所提供的案例材料并分组回答下面问题： Plot the data from the first three runs. Plot yield against oven temp. Does the data support the operator’s claim? What additional questions might you have? 把首次实验的三次运行结果画在图上，以烘烤温度为横轴画出产出率。这些数据支持生产部门的说法吗？你有其它问题吗？ ? Plot the data from the next three runs. Plot yield against time. Does this data support the operator’s claim? ? 把第二次实验的三次运行结果画在图上，以时间为横轴画出产出率。这些数据支持生产部门的说法吗？ Is there a way to show all data points on one chart? 有没有办法把所有数据画在一张表中？;Read the case material provided and prepare the following as teams: 阅读所提供的案例材料并分组回答下面问题： Where does the data tell you is the best place to run when the yield is plotted against time on the x-axis, and temp on the y-axis? Does this support the operator’s contention? If this point is not the optimal, do you get a signal or pointer to an area of higher yield?
