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.
6 a1 c( }' W; l1 w1 ^5 \  Loads are processed by each operator for the following time:
) {9 [) h( n: l( r- h9 k) I3 Q  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
: [0 F" J! ?" Z1 L9 w3 P  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.
! N, f3 x7 a" G" R& I' Y  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.

+ j7 ]& i0 m2 L' \" ]% d问题：
After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
3 O3 M* R- K: amove into Q_wait /*Capacity is infinte*/
3 P* ?' W5 E/ O; r, Q  Qmove into Q_process /*Single capacity*/
5 Y  u- E0 h% }- W% Y0 O: b; `. [
use R_A for n 60,10 min /*Resource A*/

send to P_B
end

P_B and P_C is similar

in P_C, you need to send to die.
