Problem 7.4

• A part arrives every ten minutes to a system
  having three workstations (A,B, and C), where
  each workstation has a single machine the first
  part arrives at time 0. There are four part
  types, each with equal probability of arriving.
  The process plans for the four part types are
  given on the next slide. The entries for the
  process times are the parameters for a triangular
  distribution. Assume that the transfer time
  between arrival and the first station, between
  all stations, and between the last station and
  the system exit is three minutes. Use the
  Sequence Feature to direct the parts through the
  system and to assign the processing times at each
  station. Use the Sets feature to collect cycle
  times (total times in system ) or each of the
  part types separately. Animate the model and run
  for 10,000 minutes.
