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.
" _3 J" |1 Z1 H6 P5 a6 F* A  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.
  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.
6 p0 i/ E! ?% C! I2 U- k3 V/ ^8 n  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
3 S! d. J6 D" O  v( W: XSend 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.
/ s# c4 ^* U; t6 B3 L
问题：
* c# r: A1 i2 m& x& `0 E& E% |8 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*/

use R_A for n 60,10 min /*Resource A*/

send to P_B
end

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