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，
/ u) m8 D2 U7 P1 v" L- k# t5 p  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.
2 M# Z+ B, ]1 y- [, @% a  Loads are processed by each operator for the following time:
9 v9 O  C: K5 A3 c  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.
3 j4 B% g% U" k* H) t4 l8 I' N  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
' `9 A7 a, `+ l) cSend 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：
8 u$ ?0 M# R& S. e& ]# a! X- mAfter 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*/
% z! o/ a* f9 n6 q' o
: v% Y/ h* C2 B9 @use R_A for n 60,10 min /*Resource A*/

7 f6 v3 y8 N$ M& z* Asend to P_B
5 l# |, O4 t4 \7 J( H+ d, @end

P_B and P_C is similar
triangular 30,60,90 min
- W! [( e- a( s( p! pu 60,30 min
. x: j. z  y+ ~' \2 `& q* a% ~, F

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.
