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,, f9 D$ Y. \' U3 X. D$ g- {
  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.6 W8 b. ], H' g- Y9 e! @1 N3 U
  Loads are processed by each operator for the following time:
/ v2 S  i0 |. |5 s4 `  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- e3 W  p3 N5 ]7 l2 f  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.1 r$ _$ i) C) ?
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.) F1 M: C" X% W0 ^" A
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.
# V2 g8 T/ A3 W! V& j$ D
% h5 a5 W6 _9 `; |3 F问题:; w/ V, d* k) x9 w( h5 v5 T
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激!
