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,
- x5 _9 \+ w6 j+ |. I1 |( D  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.
0 j* d& j1 H' o+ a  z5 w& z  Loads are processed by each operator for the following time:
. |  s; J3 _, c/ O' E0 R0 ?  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
) p) [* p. g2 h8 f  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./ X4 w/ h  j) `) k* \  V7 E  H4 |
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.; V5 p3 n& l2 O; W5 X6 a# S  d- u& o! @
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." E* I6 G1 h' @
9 N- O, _) f/ M# X! `/ i
问题:( n) M+ I+ c; l2 L# [
After running the model for 10,000 days, what was the average number of loads in each process?  R8 {) G7 E% ?5 `

不胜感激!
