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，
  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.
' y3 m3 i  B7 o( R% U1 t  Loads are processed by each operator for the following time:
5 C5 t; T% i$ F  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
5 u& i. F9 J$ `- u+ Y  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.
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.

; j  ~! K8 l2 d. k2 K0 A, p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*/
* N8 R: o, |: f" u1 s" Xmove into Q_process /*Single capacity*/

: E4 ^. C/ M3 g! B9 I  F7 h* K$ `use R_A for n 60,10 min /*Resource A*/
2 @/ D  n3 K, L  V
send to P_B
end
; H  P$ I9 `, B$ K/ ?; {& e' r8 ?. s
P_B and P_C is similar
5 E) u7 M" Z  Qtriangular 30,60,90 min

$ n+ p& _, k/ T5 D7 y% l4 k

% N$ h8 Y' W0 T. d; Win 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.


$ t6 Y% S/ x& m. yRemember to turn off the animation before you run your model.
