刚刚开始学auto mod,这道题目搞不明白,希望大家看看 题目是这样的,0 U0 N- r: g, ~9 U* _" `6 L" L" X
  Create a new model containing three independent processes, each with one operator. In each process, loads first move into an infinite capacity waiting queue, then into a single-capacity processing queue.) `% T, j4 K5 n, X  f( @3 h
  Loads are processed by each operator for the following time:
! r$ E1 E* O3 ?- }& t- c/ N* f# d  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.! b! B, ?) t( b7 Q" }
  Worker_B does the job according to a triangular distribution with a min of 30 mins, most likely value of 60 mins, and a max of 90 mins.; W5 E0 i- _9 X1 T) ?. F+ z
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
  @2 z' `0 i7 }( w9 o0 Y$ vSend loads to each pocess at the same rate (an exponentially distributed inter-arrival time with a mean of 68 mins) to understand the difference in the processing times of the three workers.& o' e- W2 E  ?/ H' t

After running the model for 10,000 days, what was the average number of loads in each process?2 u: @8 w: |4 T/ M( A: o" n

Remember to turn off the animation before you run your model.
