Subject: Field Data
Message:
When analyzing field data for specific part failures (like an electric motor)in a large population - Do you use time to first failure for unique units and then do Weibull plots? Do you ignore any follow up failures of this part in these units? The sample size would be several hundred units. I would like to use this information in determining base failure rates for future reliability predictions. Thank you
