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 x" R+ M& v) [8 p6 u
  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.
; P+ v4 o- b: X+ K+ d! T# e$ f0 c  Loads are processed by each operator for the following time:
" z- {- ?) Z0 s8 o2 e3 u# @3 M  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
+ L$ e% k- k( b: I2 e  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.
% k+ f( q% V% G9 f  p  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.5 g3 ^9 S& j5 |7 M3 ?7 B
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.$ _* b. G9 A  C1 F, H
; l% d6 k9 \0 `1 q& k+ b2 N+ p% v
问题:/ d' B2 _2 N5 k7 Q3 m' o4 _9 f" O8 d
After running the model for 10,000 days, what was the average number of loads in each process?
