days with airplanes
We did lots of improvements with planes this week. Yesterday we finished improving the process of making airplanes and today we started analyzing dropping time of helicopters, which were made from papers by ourselves. At first, I am happy that I learned how to make a simple helicopter, it is quite funny. Next, I really prefer the way of studying that we did in our classes¡ªlearning processes by practicing.
My classmates said to me this afternoon that they thought the methodologies in six sigma were very amazing and interesting. They were certainly correct. I enjoy these methods very well as even though some of them are quite simple and easy to be applied, they can still solve a great deal of complex problems. For example, we selected 6 control factors and 1 noise factor which could have significant impact on helicopters and were asked to analyze how strong the effects could be with each factors. It sounded like a difficult task, however I¡¯m sure it can be done within several minutes by using proper statistical software. How wonderful it is! And of course, in the case, we can do much more accurate calculations. We can put the different interactions between two columns into different columns if they are allowed, we can analyze the third-level interactions or even more, so that we may get better results. Anyway, these days are tired but fruitful.
