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，
& i" e$ x' S% k2 J  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.
+ F% z2 l+ T/ J; L! r: A( B5 i  Loads are processed by each operator for the following time:
, O! T5 j- }5 ?& a. U. A  H' G  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
6 @9 a1 b3 M6 V1 b) z' o  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.
. P" E1 x! @* k0 A  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.
1 x: F3 ~- d% E$ V
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*/
* j' j6 `/ f1 x: P# \5 c) Q4 tmove into Q_process /*Single capacity*/
1 g, o' ~! O0 }! Y( r& H' u
0 S0 t9 c- ]1 e. b0 O) I" ruse R_A for n 60,10 min /*Resource A*/

send to P_B
( R  l5 f( h' M/ t- \end
4 ~7 J) g2 N3 ~  A
P_B and P_C is similar
triangular 30,60,90 min
u 60,30 min


in P_C, you need to send to die.
- i/ _- T# }6 F
0 u8 N2 o5 ^$ s5 e, YThen 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.
