A manufacturing company operates two production lines. When both lines are operating, the production rate on each line is 500 units per hour. At this production rate the failure rate of line 1 is 3 failures per 8-hr day (CFR) and the failure rate of line 2 is 2 failures per 8-hr day. When one line fails, the production rate of the second line must be increased in order to make production quotas. At the increased rate of 800 units per hour, the failure rate of line 1 is 6 per 8-hr day and the failure rate of line 2 is 3 per 8-hr day. Find the MTTF and the reliability of the production system over a 1 -hr and over an 8-hr production run.
