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，
3 n3 h6 Q2 l; ~- A* [; J  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.
6 d* s6 y4 C' O( 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.
  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.
& N" [) X# u( e5 @# ?  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.
3 B* c5 Q6 p+ k7 y
问题：
After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
7 ^  [2 o' S- ]5 ~. u  Y4 Vmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/

end

in P_C, you need to send to die.

3 i. m! F  n9 I5 vThen You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
