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.
: a  u+ X9 Y' |8 G  Loads are processed by each operator for the following time:
9 k. d0 V6 Y4 j6 `  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
' j  p" E; j. l5 X# U! f3 L  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.
- s0 W7 H5 E' ~0 _9 |  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
8 e2 t& V! M: ESend 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.

问题：
6 z, `1 l( j7 W& |- JAfter running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
# Z' F4 t  P2 m
use R_A for n 60,10 min /*Resource A*/

send to P_B

in P_C, you need to send to die.
