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，
. h: e- I5 G+ y# Z! T; p- X  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.
. h" S; _/ k! S, a3 h) A$ Y+ u  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.
. S" M) |  C: a8 {8 Z1 {' f  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.
5 u( n9 U6 }' z  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 O( R  [0 I& `7 h) d4 G" `( 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*/
5 C$ W( V, i+ @move into Q_process /*Single capacity*/
1 K4 x: x& H2 C# |

send to P_B
end

in P_C, you need to send to die.
& v! k% I, E/ o
- R, g; w/ z6 eThen 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.
