本人初学auto mod,有一道题目希望大家赐教

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，
( M! N' o  [# \# B" e2 Y  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.
  Loads are processed by each operator for the following time:
5 J0 O: s4 ~) `  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 h# k6 j& p) e: t1 X  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.
$ b% _; L+ g, t) M' y( l! A  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
. w! K% Y* {  Z" wSend 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.

" F, \% w# U& ~+ x3 f" h问题：
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激！

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
% i9 j+ n; _# F$ |. E% n$ n! ^
/ ^$ K3 l* N, |  duse R_A for n 60,10 min /*Resource A*/
- ?% e8 T( h) R& \4 `3 L
send to P_B
end
0 V/ I3 v, n8 b; r& |8 v, C
P_B and P_C is similar

8 X6 h6 \& P) _# g) q5 @
* |* m- }6 T( B- y1 z1 P; Y; u. Pin P_C, you need to send to die.

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.


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