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.
  Loads are processed by each operator for the following time:
! X3 `' j6 ?1 t2 s! w+ V( c# E  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
: }. u0 O' f/ p, x2 n2 x) t2 L* W  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.
  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.

: l" Q" c0 h+ i: G5 x  `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
move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

9 h( h0 ]" A; z$ Z/ tuse R_A for n 60,10 min /*Resource A*/
) Y2 G1 m! B) _7 K2 g  f
send to P_B
end

P_B and P_C is similar
+ y: p$ U7 u# E& q0 n, itriangular 30,60,90 min
6 x% K! C; }; \! su 60,30 min

) g' {4 y2 `( J: q6 z' I! n/ u
& u8 Q- r, t" M; Nin P_C, you need to send to die.

# s" y( E0 p% {  p- wThen 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.
