Subject: Reliability predictions
I have a failure data for a component as follows(failed hours) 1,574,611,887,1250,1445,2480,2750,3234,3540,3900,4001,4124, 4180 and 4189 hours I calculated the relibility of this part using this failed data after plotting manually on weibull plot as 0.112 considering 5000 hours Warranty life. But how can I derive the actual reliability of this component as already some 10000 components are running in field and have already crossed 5000 hours which is our warranty life. Please advice me the appropriate formula to get the actual reliability of this component. Thanks,
