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，
% g; j# a8 q; V! l* H; N  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:
+ i6 W: _# e5 A- L9 I6 V5 t  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
; r4 N+ K+ E/ X' z7 R7 B' v! 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.
* J/ h4 D; a/ ^' g, p, a* [  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
5 [2 S4 W5 F3 FSend 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.
5 b4 o: D& d% j5 r/ c9 P  Y
问题：
& A5 f- W, B3 u1 Z9 jAfter 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
9 C% C7 m) L. p2 |/ Omove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

" x1 F0 o/ o  S& m3 r  euse R_A for n 60,10 min /*Resource A*/
6 O5 I" E" V, o% A
send to P_B
end

, @: W  D+ A- x3 u0 ]" DP_B and P_C is similar
: i/ v8 d) H7 k* Y; T( xtriangular 30,60,90 min
/ ^4 i: x3 }' d) Vu 60,30 min


in P_C, you need to send to die.
3 w" t, p, {" t/ T" X: r
2 G; J) n  X( O7 Y) o$ f! N" O1 e7 |4 JThen You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
5 N: M; Y$ y% D$ T

Remember to turn off the animation before you run your model.
