Setup time on a certain production machine is 2.0 hr. Batch size is 60 parts, and operation cycle time is 2.0 min. Parts are processes sequentially. The reliability of this machine is characterized by a mean time between failures of 40 hr and a mean time to repair of 5 hr. Taking into account the availability of the machine, the average hourly production rate is closest to: a. 14 pc/hr b. 11 pc/hr c. 12 pc/hr d. 15 pc/hr e. 13 pc/hr
