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) `2 H' R3 r. Y  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:
/ j  Q' {8 e+ f. _2 c  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
7 L/ b4 a3 ?9 D  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.
4 l: j3 M& M8 _! \4 L2 E# BSend 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：
; H8 p5 N$ c5 RAfter 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*/
+ w8 b6 [5 S/ y( P/ l" a/ fmove into Q_process /*Single capacity*/
" @: e! ^1 I' h/ _! M2 t
% Q* e  A; Q: E# S- @6 G1 @! Zuse R_A for n 60,10 min /*Resource A*/

send to P_B
end

P_B and P_C is similar

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.
