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.
8 t6 j4 N1 j/ v, R7 G( d  Loads are processed by each operator for the following time:
2 j( F, |5 \: T  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.
! K% q. }. v% s1 ^6 y3 w% h4 d/ _  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.

问题：
' a* h+ B: C8 ~' Q8 k- O9 rAfter 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*/
/ v# ^7 h" M# C# \- ?move into Q_process /*Single capacity*/
# T+ R  m& p# o: K3 }
use R_A for n 60,10 min /*Resource A*/
+ Q+ Z. m: F8 u3 Y

P_B and P_C is similar

% b9 E8 u8 n) O" oin 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.

Remember to turn off the animation before you run your model.
