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，
% {  c# V. h: b/ p) t, d' {1 q  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:
/ ?' q* K+ k+ A; U# ~. z5 Q  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.
5 F) K, h) [. w6 |" }  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.
7 A! Q0 _, \0 F9 Q7 b
问题：
& z/ Q8 X+ F) A% ?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
& i$ r2 z" W9 lmove into Q_wait /*Capacity is infinte*/
7 `! A' |) d! T3 l; ^* X4 Qmove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
) L! h# \/ ]' d( d" C
. i8 w) @, S4 |. Qsend to P_B
end

P_B and P_C is similar
+ ?+ S" m7 @  p7 G2 K* mtriangular 30,60,90 min
u 60,30 min
( _) _+ q% U1 v7 j4 s/ l

in P_C, you need to send to die.

8 l0 z  G7 r# \" }Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.


  ]; D  b% b, S0 A1 a6 `' E" HRemember to turn off the animation before you run your model.
