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.
% x+ Z" J3 U! `. h, Y  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.
  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.
5 ]# b' w+ r* k
问题：
After running the model for 10,000 days, what was the average number of loads in each process?
* G" Z7 T' |  f) r9 o- i
不胜感激！

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
7 }/ r* ~" K4 W  O! O0 V5 O! k1 K, Ymove into Q_process /*Single capacity*/
9 j' z0 v. k1 s# \1 |9 t
use R_A for n 60,10 min /*Resource A*/
+ i, E- `% `- }, R
send to P_B
end

P_B and P_C is similar
triangular 30,60,90 min
u 60,30 min


in P_C, you need to send to die.

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.


  Y/ F- k; p. ?/ Q/ p2 n) S0 bRemember to turn off the animation before you run your model.
