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，
  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.
. O" t: a- i( v  o  Loads are processed by each operator for the following time:
7 t! q+ \, K' V( C  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
% M) b! j) }+ K8 M+ p! C  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.
" x( Z$ h- S, y8 _: j0 I  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
. ], y" P2 z9 j3 `( ZSend 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.
3 U: I2 y' X  B9 {3 d& N
) s; N9 y' x+ u' h问题：
# M  y' h% ?; m$ pAfter running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
# Q$ [9 j! |8 M( j5 Mmove into Q_wait /*Capacity is infinte*/
# d6 Y" ^$ d; t: Z+ Q% A0 Qmove into Q_process /*Single capacity*/
. n4 g& i* a: U9 x% ^
use R_A for n 60,10 min /*Resource A*/
" O& N% ~$ A% @; e! F- Z& b6 y
send to P_B
end

  ~5 L( R2 g9 S9 d& d! w+ ^P_B and P_C is similar
4 d9 N6 x. g+ _! o  k* Y! h* R; b  Atriangular 30,60,90 min
0 X( G5 L+ W0 G, Yu 60,30 min


in P_C, you need to send to die.
' w0 F: @* h  i  b5 \8 ]
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.
