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.
. z- k% t, Y2 Q  Loads are processed by each operator for the following time:
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* @$ P/ O7 r' E8 |$ Z, ]" ~  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.
3 t, v, |0 }9 t' X0 D5 ]! OSend 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：
) |6 d3 v  u) SAfter 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*/

- r2 ^- Y9 [4 ?6 t0 Duse R_A for n 60,10 min /*Resource A*/

" f  ~& `  a1 L0 ~( `7 ~send to P_B
end

2 R& F5 S7 c% fu 60,30 min


% }# Z5 M7 C" Ein 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.
