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.
9 w2 J4 @% B9 ]% r/ R: W  M! o  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.
6 O7 ]  r# x6 e0 @! o6 Y; R  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.
8 w# m- O2 i# B' P3 N' W5 a$ O2 ~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.
/ L8 d3 G0 ^' b+ C- r! }
问题：
1 u3 c7 o% w8 j/ `After running the model for 10,000 days, what was the average number of loads in each process?
* J4 S( d! b! v+ o
  F. `6 ~: p: s# h+ ^4 N' x3 `不胜感激！

begin P_A arriving
7 P. r* B9 E& {5 gmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
/ B  }/ R/ i0 V/ _) R
use R_A for n 60,10 min /*Resource A*/

- Z* w: X; a1 Tsend to P_B
end

P_B and P_C is similar
$ p! ~% w! W5 G- s( striangular 30,60,90 min
u 60,30 min
8 L3 ?" J+ P# }& S/ G, D+ u
5 M9 `; K# v% E, V# V# K7 k
4 [1 v! h3 k2 L$ Y4 \% P: B7 Oin P_C, you need to send to die.
! v; F+ M; y; h  v- k) A, |
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.
