本人初学auto mod,有一道题目希望大家赐教

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.
1 F% L) l- k1 r2 N7 v  Loads are processed by each operator for the following time:
3 v- m0 X1 @  s3 O  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  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.
( Z0 a' R7 Q" b  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
% F' a( p! Z5 ?+ G6 q1 a% uSend 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：
5 j/ z, [4 ^) |After running the model for 10,000 days, what was the average number of loads in each process?

in P_C, you need to send to die.

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