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,6 m  b: B7 [4 [
  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.# {+ w# _- e  @
  Loads are processed by each operator for the following time:
, p- A3 K% A+ a; d/ S0 L5 Q  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
6 [% P( F9 \9 K% Y  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.7 P* _: c8 T; R9 ^. {. p
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
  S% X" J0 s# e# FSend 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.
0 K+ F+ k. F* s' [" g& Q, f% C2 H# ?+ u& F7 O- J
问题:& ~7 ^3 T3 z- `- ~; b* L
After 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.
