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，
% k* K1 v& Y  l9 v* |1 G  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.
+ j! }7 a. ^1 e; t+ ?$ @5 [* s  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.
+ n1 P$ V0 Q- L  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.
+ J3 s  S' v, b6 u
& j" r( U+ C6 W$ E8 ~% c. K3 R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*/

' I6 ]+ D/ F5 k, O+ ~use R_A for n 60,10 min /*Resource A*/

send to P_B
end

in P_C, you need to send to die.

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