Reliability Analysis of life data with Multiple Failure Modes

Dear friends, I am happy to release this video on reliability analysis of life data with multiple failure modes. The analysis procedure is illustrated fully in Minitab software with a real-life case study with six failure modes. The concept is that when a system fails for one failure mode at time t, this data of time is right censored data for other failure modes! Analysis in Minitab can be performed in one single command! Viewers are requested to watch the following videos before watching this video:

I am sure, viewers will find this video useful!

Sir, thanks for immaculate tutorials. Where in many of them won’t get this upfront. So blessed are the followers of this channel. Many thanks sir.

You are most welcome! Appreciate your keen interest! PLease share with others who may be interested!

Sure sir

what are the typical sources of Reliability Data

[@uhemant1]

Thanks. These could be field failure data, reliability test data, components tests data etc.

Hi, what is the different between Maximum Likelihood to Least Square? why do you choose Least Square?

[@instituteofqualityandrelia7902]

MLE is an analytical procedure that maximises the likelihood function using calculus. According to Robert Abernathy, MLE is appropriate when the data is large, typically more than 21. In lease square, we minimise the sum of squares of errors between observed and fitted points. Hope this helps.

Good evening!
Dear Hemant,
Can you talk about reliability analysis of life data with multiple failure modes and the effect of the "dogleg and outlier "?
Thanks!

[@instituteofqualityandrelia7902]

Hello Jonailson, I am not sure if I understand your question. But Weibull analysis of any data is applicable for a particular failure mode. If there are outliers in the data, it probably means that the failure modes are different for such data points and should be omitted if the failure mode is different.
Good luck..Hemant

@@instituteofqualityandrelia7902 Thank you Hemant!

[@samnazarian3807]

Thanks for the video. Could you please advise why in the case of the data that you presented in the video, the repairable system analysis is not better approach to use?

[@instituteofqualityandrelia7902]

Thanks for asking that question. The purpose of study was to identify priority for improving the durability by identification of the failure mode(s) having lower B10 life.

Good video. I'll try to analyze one prototipe. How Could I apply this model?

[@instituteofqualityandrelia7902]

If the test data has multiple failure modes, you may be apply the model in a similar manner. Thanks.

[@mioumitsou]

why am I geting the following error:
* ERROR * Least squares estimates could not be calculated for these data. There must be at
least one distinct plot point on a probability plot for each estimated parameter.

[@instituteofqualityandrelia7902]

I cannot comment. Either some mistake in commands and options, or duevto some changes in Minitab versions.

Difference between parametric and non parametric distributions

[@uhemant1]

The nonparametric method is used if no distribution fits. Kaplan Meier is a nonparametric alternative. See related video posted in our channel.

Minitab generate analysis data for iOS app?

[@instituteofqualityandrelia7902]

I do not understand your question. Please clarify.

[@modestliving9662]

What version of minitab is it?

[@instituteofqualityandrelia7902]

I think it would be 17.

[@kuldeepjayaswal9933]

Name of software

[@instituteofqualityandrelia7902]

I have used Minitab software. There are other software such as Weibull++.
