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，
, X$ P) O# h2 e) o! Q0 N8 B6 F  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:
  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.
) F" |+ M# x4 t+ F6 @: ISend 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.
4 Q8 _* o* J$ N* ]9 j+ t4 H& Z; q
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
move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
8 Z7 ?8 X) @2 P$ s1 A  o
4 c) e  O8 c4 H5 ksend to P_B
end

& P1 U2 j% c# H: i+ c$ d& XP_B and P_C is similar
9 Q) a7 N) z0 u7 Ptriangular 30,60,90 min

$ z+ Y- }0 T5 T$ O: ^$ C& k! t- yin P_C, you need to send to die.
  c! E, X4 O! b* I6 H+ ]
Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.


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