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，
2 f4 `5 P  E& a3 X* @$ M  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.
+ c% w& W" w" R5 J2 q$ H! S  Loads are processed by each operator for the following time:
9 o% e1 d2 W. d, }5 i" k: u% V  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& ~4 _$ o! C4 w9 X; |4 \0 _0 X8 Z  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.
( `- \1 }% B) W. n5 [, C: _7 b5 z2 F  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, U  R6 f& H1 W2 Y' V1 F( M" qSend 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.

! b8 p, k3 W. W3 C- L/ |/ d  ]问题：
After 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*/

8 q7 c8 P3 C4 Nsend to P_B
end
/ x2 }& T% t- z! r* P2 W
  N& x+ [; @; I  ]P_B and P_C is similar
triangular 30,60,90 min
3 Q- e+ l& ?2 H  iu 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.

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