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.
. f, I* g* S9 I6 N# Y  Loads are processed by each operator for the following time:
$ i/ X" g; N2 l8 N" @. x. c- y  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& A; i$ R, C; m8 a  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.
% a$ c  h* R* F3 U) ?  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
: g: N1 p* u1 d: USend 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：
, O8 t8 Y; j. A- X- oAfter running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
+ P8 l/ p: a- q6 r2 T$ ~2 |) [) E9 f  Tmove into Q_wait /*Capacity is infinte*/
6 S% Y; U2 e) ~6 Z- A: L8 P3 s- Tmove into Q_process /*Single capacity*/
  v* Y# r7 e( B$ ~  ?: e; _
use R_A for n 60,10 min /*Resource A*/

send to P_B
end

P_B and P_C is similar
9 o/ W" X! j: t3 \triangular 30,60,90 min
0 f9 o: p* z$ H7 t+ O. }! Uu 60,30 min

- @" P9 r1 r! \0 W/ @( Rin 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.
