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,  |2 V8 a) {$ _6 P
  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.
% u% j' \7 ]' i/ O3 o  Loads are processed by each operator for the following time:
2 A9 `' G7 g. S& d- Y) [/ f7 {  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins." x/ r# R2 }* }5 U8 ^
  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# V4 w/ L) W9 c% w  v5 r  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
. ~1 B0 D+ w& m) I3 vSend 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." B8 L2 o9 l6 M4 X& }8 {

& d. v. k0 P) P% a/ m# ~  v5 \6 x! P2 V问题:3 U: K" k% B: l0 e  F3 o! P3 R* E0 {
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.
