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，
4 X/ u2 b6 `/ T' D, a, o" Z3 B3 b  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:
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  \& o2 b4 d5 H5 O2 P4 I3 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.
& w2 X- |; J/ ^  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
+ b& s) [6 O1 {5 Y# Y, C; ySend 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.
# l, \# K. W9 x) n! ^7 o
问题：
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*/
move into Q_process /*Single capacity*/

. ^, O; l# D- h$ X% o; huse R_A for n 60,10 min /*Resource A*/

send to P_B
end

; j2 \* q2 D9 M1 w' Y& o$ yP_B and P_C is similar

/ @, d3 W) R1 U8 m# |; |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.
