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.
2 X/ T( g; _4 o: j5 j- M8 v  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.
4 t; A1 f- S7 s; j  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
5 G% g) _( M3 m# P  hSend 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.

1 e/ Z* m% M4 y问题：
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激！

begin P_A arriving
( v+ X3 N4 O* |) R  hmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

/ t, f3 Z. f, @# N6 L6 Puse R_A for n 60,10 min /*Resource A*/

send to P_B
end
