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，
# [7 v8 B+ U" R  l9 `# |8 _3 v& G  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:
$ z* W  a  Y" H# X8 b9 Q  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
" I& t! F; ^  K( q- @  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.
( b9 y% I, A( Z5 l0 V) |3 I5 U  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
+ m9 h4 I, F" O6 a1 N( Z% uSend 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.

: a9 c) V) @! n% |. ~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*/
2 E! w9 k4 {: ]. gmove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
, Q) M  a; v. L  a  e
send to P_B
end

4 N& B9 @+ z; A- s& w/ P$ u7 QP_B and P_C is similar
triangular 30,60,90 min
. M) v" l$ G( i* S( l! ~" @# Vu 60,30 min
# J8 J( C; D: s; O# w" Y5 U2 S

in P_C, you need to send to die.

% Y% t2 l. V: q. D7 OThen You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.


- D) c' C$ r- n7 @Remember to turn off the animation before you run your model.
