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，
; F) H1 V# o$ `( c" t  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.
  O$ f$ W. G2 s1 _! A; i9 I  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.
; L3 g: c2 q9 @' wSend 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.
9 }- ?) b  R1 R8 ?8 R( L
" v, C& C" `" s6 w  _& 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
8 b8 Y/ {, A! vmove into Q_wait /*Capacity is infinte*/
, g5 E* `$ W- U2 u0 kmove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
% w* N/ [% {  N) s: ?: x- ?: q
send to P_B
end

, u8 t/ S& H/ b5 o- L9 }( X) l4 iin 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.
