- Hi everyone!!
In this video I show how to make a reliability analysis of field failures using minitab 18.
If you are interested into get more information about this topic just drop me an email.

Very good video with a good practical example and explanation
Muchas Gracias Jorge por compartir tu conocimiento
Thanks for positing this. It was a really useful and easy to follow tutorial. Great work.
Thanks Richard, Did you see the Accelerated Life Testing Video?
Wonderful explanation
This was really useful - I had not used Minitab for along time and needed to check a Weibull report someone had made - it was wrong!
Good to hear that. Not always Weibull is the best choice, this is something that always see in the industry.
Very good training material !
Thank you Jose!
I have run the analysis in JMP before but being new to Minitab was a giving me some trouble.
Awesome! Succinct, but totally understandable. The interpretation of the results is the best part. Thanks, Jorge. You helped me a lot.
Excellent video! Thank you.
Excellent video !
Good explanation
Excellent explanation. Please guide how to find sample size of vehicle for given reliability target and confidence level and define time period.
Amazing!!!
Tks for your explanation!
Thanks!!
Hi Jorge, nice presentation. You mention you are making your next videos for warranty data and Accelerate Livetime Testing. The warranty data is there , I am looking forward to see the ALT video. When are you planning to do so? WKR Simon
Hi Simon, I took a break on this, but now with the quarantine I will do it. I promise.
Excelente explicación, great job, saludos
Excelente video, solo mencionar que podemos utilizar la letra F para censura por la derecha tipo dos y no solo la letra C
Thank you so much Sir.
Thank you, thank you, thank you!
Hi Jorge, Thanks for the video. It was really helpful.
I have a question, when you were discussing CDF plot, you mentioned that 5% of the vehicles WILL fail for 10000 miles. But because it is a distribution fitted on the existing dataset, CDF tells that 5% of failures HAD happened before 10000 miles right? It tells the behavior of the current dataset right!?
Sorry for the late response on this, it is correct to make the statement that we will get 5.7% failures before 10000 because at the end this also apply for the future units that will be produce until a change it is been made.
Hi there Jorge...!!! May I ask you something? Which one is the reason to accumulate the TTF when we analyze data on minitab? I been working in a reliability analysis and then when I intro my TTF (No accumulated) I got a result way different than if instead I would intro same data but accumulated. Any suggestions? and Thanks in advance.
Hi, not really sure what you mean by accumulate TTF?
Hi Jorge, this a great learning, thanks for video. Request your guidance for my analysis. Actually i want to use weibull for my tool failure after producing some parts randomly. for example i will get some failure at different cumulative values like at 20, 80,120,500,1200,1500,5000. For me its no of failures for cumulative production. How i can use this weibull for my analysis.
Please waiting for your reply.
Hi Prakash,I did not get your example. Could you explain further? jogongut@hotmail.com
Thanks for this amazing video! Is it possible to run a 3-paremeters Weibull analysis in Minitab? How to? I have different samples undergoing stress in Newton. I know the exact second in which i have the failure.
Yes, it is possible.
Thank you jorge .But how can we use Least square analysis for a censored data, we generally use MLE for censored data types, Yes based on sample size it is ok can you please give your views on this
Hi, could we discuss about an specific example? All depends on you data sample.
Hi Jorge, how to do the reliability analysis for a certain equipment that havent experienced any failures since it started to operate (it doesnt have failure data)?
Only way is with an acelerate life test.
Excuse me sir, can you explain me how many data that i have to need if i want to use max likelihood method?
Hi, MLE works with almost 3 data but I will suggest to work with 10 or more.
why in the exponential correlation coefficient the value is only * ?
Hi, sorry for the late response. I was in a break of this. The * is displayed when is very very low the correlation coefficient
hello can show example when failures are defined? (not only 1 as in your example) Thank you!
Thanks it was very useful..please I’m waiting for the video of lifetime reliability. Can we use minitab to compare the Bayesian estimation of reliability of normal distribution with another classical methods?
Hi, I already upload the accelerated life testing analysis video. Thanks for your feedback.
Hola Jorge me gusto el video, podrias ayudarme con un analisis de una llanta. mi cliente tiene como tope 72T Kilometers sin problemas, pero tuve una ponchadura a 66T kilometers, pero tengo las otras 3 llantas que pasaron la prueba de 72Thousand Kilometers y por la que falla me pide hacer Weibull analisys para B10 y B50 en esa llanta, tengo mediciones de mis llantas cada 1000 kilometros
Disculpa la tardanza en mi respuesta, con una sola falla y 3 datos censados es imposible realizar una predicción adecuada.
Please make a Video on accelerated life testing on minitab in English sir.
I took I break on this, but now with the quarantine I will make it.
Why you select not maximum likelihood but least square ?
In this case because the quantity of censored or suspension data is very low, some times you have huge number of censored data and in this condition is better the maximum likehood
@@JorgeGonzalez-yf6qo thanks a lot.
Sir,
Please add video on accelerated reliability in english
I took I break on this, but now with the quarantine I will make it.
Please make video in English
Make video on accelerated life testing in english
I took I break on this, but now with the quarantine I will make it.
Hi, I made already the accelerated life testing video you requested. Did you see it?
