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，
, O. d7 K0 t$ h! q  m  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:
4 p4 |  m# C, n6 ]7 h  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.
. D7 P- H0 A+ f" ~# [& I7 {$ L  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
9 A  k1 D; w) f/ W* U2 SSend 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.
! B9 D" ^: B8 m
问题：
+ p1 |4 E) L$ C! I4 U& gAfter 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*/

use R_A for n 60,10 min /*Resource A*/
" \( ?7 O# A, r' B9 j
send to P_B

in P_C, you need to send to die.

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