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，
% n& f( N" \5 K, }  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 F) T5 k- `3 }6 B& `5 E4 x& k; d4 c  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.
/ l/ n) a# y, c" \  H+ 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.
9 U; K+ }% a5 M  Y4 N$ ]
问题：
* n) |: H5 C/ g5 P* k  hAfter 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
" M8 n: ]; h% y3 P+ Zmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
4 C! E9 n1 a/ J' t- r
use R_A for n 60,10 min /*Resource A*/
# u& B* @8 W. K7 e& |( j$ G" [
send to P_B
end

P_B and P_C is similar

; i. J$ L2 Z9 `& Min 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.
