The Corrupting Influence of Variability - Diagnostics and Improvements
5 important questions on The Corrupting Influence of Variability - Diagnostics and Improvements
Process batch time is driven by process batch size. Give the two basic means for reducing (sequential or simultaneous)process batch size.
1. Batching optimization to better balance batch time with queue time due to high utilization.
2. Setup reduction to allow smaller batch sizes without increasing utilization.
Which two ways are there to increase throughput?
Increasing the bottle neck rate or increasing bottleneck utilization.
When does it make sense to increase the effective rate of non-bottleneck stations instead of that of the bottleneck, in order to increase throughput?
I.e. when increasing the bottleneck rate is practically infeasible, or simply when this costs too much money (or when increasing non-bottleneck rates is much cheaper).
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
For my 1st exam I got a C. Then, I started looking for ways to learn better and I came across Study Smart. Since then I have scored a A+, A, A- and another A. I highly recommend it to everyone who wants to hear it. I am so happy with it!!
I was struggling to finish all my first-year subjects for 3 years. Then I discovered Study Smart, which helped me to finish all of them within 3 months.
Because of StudySmart, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Study Smart, my average has increased significantly. I even completed a statistics course with a A+ while I'm bad at statistics. I took on extra courses this year, because of Study Smart. Thanks so much!
Ever since I started studying with StudySmart I passed all my exams !!! No more re-sits!! At first, I was happy with a pass and now I only get good grades. Many thanks!
I aced all the courses I studied with Study Smart. For law, I first scored a D, and now an A! I’m 100% sure that I’ll pass all the courses I study with Study Smart.
I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on my grades, my speed and the pleasure I have in learning.
For the first time, I finally feel totally confident about the way I learn. I have the perfect overview and make great progress in terms of speed and the grades I get. Thanks, Chris!
I immediately started to enjoy learning again, and my grades soared. All of a sudden, everything went better. I highly recommend Study Smart to all students..
Being able to create my materials online made the process of studying so much smoother and quicker. I no longer have to spend a huge amount of my time on creating my summaries.
At first, my notes were a mess. Now I use Study Smart to take my notes in a perfectly structured way. It helps me to save a lot of time and do other things I enjoy.
Students that study with Study Smart get better grades. The system applies all the learning methods in such a way that both well-performing students and students who struggle perform much better.
Hi Chris, I would like to thank you very much. Last year I scored C on a course, and this year I got an A+ thanks to your method! Thank you very much!
The largest effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school, Study Smart made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with StudySmart, I haven't had any D's. My average score is now an A and those are results I would have never had in the past
With my old method, I passed only 3 out of 8 courses. Since I started taking my notes digitally in Study Smart, I have passed all my courses on the first try. For me, StudySmart takes away the stress of wondering if I will pass or not.
Thanks to StudySmart, I passed all my exams, and with better grades than before! On top of that, I have mastered a very good study method now, which I am confident will help me earn my degree.
The book lists 8 components of cycle times, but only lists improvement options for four of them.
Why didn't they include improvement options for seemingly important CT components such as process and setup times? Can you think of ways to improve process or setup times yourself?
They didn't include improvement options for these because they are generally only a small fraction of total cycle time (for inefficient lines). If you regard more efficient lines, improving things like process and move times become more and more important.
Improving average setup times: setup time reduction 'programs' such as SMED.
Improving average effective proces times: improving availability (i.e. by training repairmen to repair faster in order to decrease MTTR), upgrading the machine to one with lower natural process time or process time variability, etc.
If cycle times would be normally distributed for a certain product family in a make to order system, and you would offer customers a lead time equal to: .
1: What service level would represent?
2: What service level would represent?
1: 97,7%
2: 50,0%
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
