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.
0 o) W/ l- p9 I% E& `2 l/ K% M/ Z6 x  Loads are processed by each operator for the following time:
) p/ K8 a4 V0 I2 d4 d/ W1 q$ C  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
6 a; d! v4 Y' ^9 W2 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.
& u8 ^$ V  _2 `* E5 ^; S2 N  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
3 }/ @& o( V3 m7 L/ f0 cSend 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.
! b, Y7 r$ d1 `2 g* x
9 j) A8 ?  ^* Q4 s) Q0 s/ {问题：
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激！

begin P_A arriving
: T& q4 b& w7 ~move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
% Q" R. h6 u; t. t
1 ^/ S! x" J; y0 X; W! [3 Ruse R_A for n 60,10 min /*Resource A*/

send to P_B
end

$ K, ^+ s0 J- e6 |  Y0 pP_B and P_C is similar
# x5 @8 b) B& ]triangular 30,60,90 min

in P_C, you need to send to die.
6 N2 c. a. L2 t0 L
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.
