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，
% j7 g- L. ~/ 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.
3 P- {1 q+ p1 s# V% S8 X  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.
7 N; r$ B! W$ S1 k. ~% a  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.
7 |+ k* m* v, N- e2 V8 G  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
+ E* y! P; Q8 W! i7 jSend 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.
4 Y+ l4 Q1 w* J5 q$ t% C
2 v! Y) I' d  a- a问题：
6 i* n. Y& b1 K8 ZAfter 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
' W, d. J; Q0 E" m$ n% rmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
+ k0 _( \. r6 U; k5 D8 a
use R_A for n 60,10 min /*Resource A*/
2 ~- ~$ |2 M+ q. P) k0 E
! W5 Z7 `: Y7 a) k2 ^* d  E; }send to P_B
end

P_B and P_C is similar
triangular 30,60,90 min

  C- |! y: b' H

6 V2 Q- F. W1 F4 Q) Jin P_C, you need to send to die.
1 l; i5 [  o; S8 D6 ^

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