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,1 |$ l0 J1 C3 i
  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.4 N, P( W4 a' H9 H4 \' ~
  Loads are processed by each operator for the following time:. X, ^1 u% P; R
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.& k/ ^* e- X) P+ V. b) H2 {  J; L- z
  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.* w' P' g+ F! F$ m5 _$ }0 R
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
4 {+ h# S6 q: QSend 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.
$ d- X- h: t: q, {* ?) p0 {% q! i
- i) |% }# p  Y; o7 p( H; H9 R$ E问题:) v' Y5 _6 S+ ?+ F% @* F2 z
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.
