Skill B3.  Consider a workstation at which parts are processed by a single machine called the H426; using this machine, the average effective processing time is 20 minutes (per part), and the standard deviation of the effective process time is 25 minutes.  Parts arrive at the rate of 2 parts per hour.  The arrival SCV = 1. What is the average cycle time at this station (in minutes)?

Skill A2.  Consider the performance of the following machine:The natural job process time has a mean equal to 4 minutes per part with a natural standard deviation of 20 seconds. The mean time to failure is 500 minutes, the mean repair time is 4 minutes, and the repair time variance is 4 minutes2.  A non-preemptive calibration step is done after every 20 parts; the mean calibration time is 5 minutes, and its standard deviation equals 1.5 minutes.  What is the mean of the effective process time (in minutes)?
