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,7 P  N4 ]! L4 r
  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.
6 @0 N% |. Q- K& Z/ x6 [% l$ P  Loads are processed by each operator for the following time:
# M2 \& q% f0 ~' }0 a3 i3 G  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 k/ i  |: k; C: ^8 A0 E$ k  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.9 t, T4 k1 d7 X0 M  `7 w
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
& U4 i8 V; p6 V/ ]! o; l1 Y* _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.
3 w# N( x7 {; \# _' U: k
' y/ r; F1 l% y! m问题:% W) W; H4 u, B0 [% q, ^; \+ D3 O3 t2 z5 I
After running the model for 10,000 days, what was the average number of loads in each process?; C$ _; ~  {6 S  i

不胜感激!
