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.
+ m7 i& `; x% d  Loads are processed by each operator for the following time:
: d" l: d6 P3 w/ l3 V# f  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  Y8 z& F# u+ D# w) X+ v  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.
7 k" C) F0 g" B: W7 i# C  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：
/ s& T4 r; m, U2 w9 r& A/ K. LAfter 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
3 x& N' k( A  O" Z9 wmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
9 z% G# u$ W8 z
use R_A for n 60,10 min /*Resource A*/
( V) a* |  F5 A+ w1 ]6 X5 {7 ?0 \
send to P_B
end

P_B and P_C is similar

in P_C, you need to send to die.

9 B% x. o; d& C( k- [8 cThen 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.
