A correct interpretation of reliability analysis is determinative for researchers and industrial developers to refine their design and also prepare proper maintenance scheduling and safety analysis. However, I still see that many designers prefer to use classical safety factors instead of reliability analysis techniques. what's your sense about this.

For example, imagine that you are going to buy a bearing and I say you this bearing's reliability is 94% for the expected life of 5 years. it means that if you test 100 bearings under normal performance, almost 6 of them should fail after 5 years. does this analysis makes sense for you in your research and development?

and if the answer is yes, how do you use the outcome of reliability analysis in your research area. the answer is important for me because I am going to start developing commercial software for reliability analysis and it is important to see what are the expectations of experts from the reliability analysis methods.

Thanks,

Sajad
