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，
: R- d+ W3 a4 u1 p9 e4 U  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.
; |# @* r5 N7 w4 t+ q: S  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.
  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.
0 Q" a7 [! k5 E& N5 k8 Z% k  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- k+ l. v" k5 F) rSend 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.
- h! q& m8 r/ T* O& y
) w2 E8 G5 C" u+ a; W# m2 W0 J问题：
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激！

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
. \8 W7 @4 h1 ~& @move into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
) }/ m4 I( W- _$ W' z* k
send to P_B
end

% W4 y6 h0 }6 Ain P_C, you need to send to die.
0 _& {4 P; @) z4 t- M! v( @+ O, s/ Y/ g
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.
