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.
5 w  f: [; j! R1 z# h7 y  Loads are processed by each operator for the following time:
) K) V! J% E; L; \/ |5 {  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
) y1 `8 ~* u6 R% R8 Q9 m0 ^" x  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.
/ J% G# n1 a2 F) X& R' q  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
' ^6 k5 Y5 ]" e6 C3 w7 PSend 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' E9 C, J! \4 e% R5 O$ h0 F- K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*/
move into Q_process /*Single capacity*/

in 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.
