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，
  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.
$ s6 q, ~$ e! e2 e  Loads are processed by each operator for the following time:
8 ~- b1 H8 F) Z. [* M( A8 o" e* e8 o  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
6 j$ n3 b6 k$ M# ^3 o/ }  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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) q3 j  l& o! S# ?5 B' K4 Y* y9 e; ZSend 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.

问题：
  R; k1 a5 P) j" N- VAfter running the model for 10,000 days, what was the average number of loads in each process?

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