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，
) u, g: o" Q2 w3 a* [! K2 {- `8 g  H  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.
2 F' I$ o0 ?! q8 D, @  Loads are processed by each operator for the following time:
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* T, S0 m8 F' W# _' n' p: I  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.
5 f( l  b3 b1 o( K9 b0 o6 y  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
Send 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：
0 i9 P! U9 d, t& o5 X5 ~/ dAfter running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving

in P_C, you need to send to die.
5 L% E# f9 M7 v8 N' t* W, p# ^) f

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