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，
1 g0 u7 {8 {5 n  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:
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  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 J2 |4 P" z% N) I  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
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.
& _; G8 H" o; O
问题：
% }9 F2 H- G4 h3 d- F3 aAfter 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*/
+ @/ N# z1 L) |/ Jmove into Q_process /*Single capacity*/

4 l2 r; c, X2 u+ F6 \6 p/ y( huse R_A for n 60,10 min /*Resource A*/
% ~/ |8 k6 U4 S' t9 W0 Y" Q9 t" p2 D
$ F, h- J+ j# N0 K9 vsend to P_B
end

P_B and P_C is similar
* f% E8 [1 n, p# X* ^( y/ V+ H: Etriangular 30,60,90 min
# a' i' f+ z: Ou 60,30 min

in P_C, you need to send to die.
8 l+ \. t) U$ r/ H5 d% l( U+ f
5 S! J3 C5 F$ hThen 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.
