A manufacturing company operates two production lines.when bothlines are operating,the production rate on each line is 500 unitsper hour.At this production rate on each line is 500 per hour.Atthis production rate the failure rate of line 1 is 3 failures per8-hr day(CFR) and the failure rate of line 2 is 2 failures per 8-hrday.when one line fails.the production rate of the second line mustbe increased in order to make production quotas.At the increasedrate of 800 units per hour,the failure rae of line 1 is 6 per 8 hrday and the failure rate of line 2 is 3 per 8 hr day.Find the MTTFand the reliability of the production system over a 1 hr and overan 8 hr production run.
