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，
; W$ H$ w! g/ b1 I; J, s. m  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.
  Loads are processed by each operator for the following time:
/ L4 z% F- S9 d; y( R0 D, I  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
$ |* [3 @7 B* W  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.
  I3 {8 f, z: Y  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) y( |6 l4 P( G& fSend 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.
2 Y) L& d+ g. @! n) f6 b
问题：

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