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,
3 W: U/ l9 V0 `* {, Z( _( 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.$ v) T! u3 I3 @' y& g' r& Y; y) C
  Loads are processed by each operator for the following time:0 |" Z7 ~& ]% {( r5 b0 J$ H5 w, y1 w
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins./ w; b9 C1 ~& F. s
  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.
# a: s  n/ D/ g$ q* ?  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.% M- L# t2 @* Q: |
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.* B7 p* {" V4 B0 ~8 h
. x. q: Z; U/ O. O
问题:* M& e  d7 d1 H
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激!

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