Jobs arrive at a work center three at a time, every 15 min. The center is staffed by one employee who takes exactly 6 min to complete each job. Jobs that are not being processed by the employee are stored at the work center and are then taken in random order. Assume that jobs begin arriving as soon as the employee reports for work and that initially there are no jobs awaiting processing from a previous shift. (a) What is the average number of jobs in the work center during the first 2 h of the employee's shift? (b) How long will the queue be after an 8-h shift?
