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，
$ v* Q% W$ L7 C7 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.
  Loads are processed by each operator for the following time:
+ X& j7 D. ]6 o+ S8 c* H  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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
+ ^$ u5 ^+ V' h' `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.
. S) V$ g4 ?+ ~

After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
' B7 M1 ~4 r: J9 Amove into Q_wait /*Capacity is infinte*/
, M3 i) z. D# v2 G8 jmove into Q_process /*Single capacity*/
& x- s8 `9 p4 v4 Z. ^: l
use R_A for n 60,10 min /*Resource A*/

send to P_B
end

. u4 n! e, v9 u' xP_B and P_C is similar

# X& i/ p9 a% k) c

in P_C, you need to send to die.
  d- b- u1 N5 H& j1 J, W  T* M
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.
