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，
  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:
( n1 h- C  Z2 s% R$ F  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
/ b; m2 w3 S, t+ `, p6 e0 w( }: z  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.
8 w3 |! H. }7 x/ i# u' J8 i  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
4 k. @) B0 E, a* w! 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.

7 G- D1 x, f" ^$ d; E" p, B问题：
After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
) D' @1 ?$ O% S; e8 ?' ]* umove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
1 t/ f5 b( Z: j" O4 B
use R_A for n 60,10 min /*Resource A*/
# N! F. l# g5 O- j8 K4 ^
send to P_B

P_B and P_C is similar

in P_C, you need to send to die.

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