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.
  Loads are processed by each operator for the following time:
0 U7 ?. ~" z& i% G  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
; I0 m0 `' Z% j8 c5 `# V. h. R  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.
# }# u7 d7 q) v  a  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- Z/ ?9 v0 y) y- l6 l0 `9 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：
1 E  q3 Z% Q' G6 t" e  j' f4 p5 XAfter 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.
