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,4 `1 h  N6 u4 {( w
  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.
9 H0 @) j% V, _5 P  Loads are processed by each operator for the following time:
+ I2 A" ~# B! o! @# q1 q5 k  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.8 G( e4 X. _5 v1 {" U
  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.0 L2 q0 m5 a5 x' n* j
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
& c; |& U8 g% `2 Z/ eSend 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.
1 o5 d3 I% R8 T* W, _  U- [
3 U. q! v+ X  e/ W+ m问题:6 k8 M0 W2 \( T; [( t  q" o' t
After running the model for 10,000 days, what was the average number of loads in each process?7 I& t+ B% w3 H' ]# ~" y, {- l

Remember to turn off the animation before you run your model.
