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，
8 a9 ~: E! `: j7 P! ]/ s3 ]3 R  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:
* ?5 p) e; g) d8 t' E( k5 {  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
; x+ Y' M& Y$ U! W' X% N6 p  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.
# H; [/ U9 ~) z& s  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.

问题：
) D6 J9 @- U- ~After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
9 H6 I/ l& [, C: Omove into Q_process /*Single capacity*/
6 i1 P+ e8 C5 C7 F+ K
use R_A for n 60,10 min /*Resource A*/

" i& E9 o% U& s: ysend to P_B
end

in 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.
