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，
" z1 c8 I+ P( G1 S( h9 ~, 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.
# u/ f' U, b$ n! o1 \  Loads are processed by each operator for the following time:
! Y% q$ `% l% E. T  i6 k  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.
6 U$ l8 c& W: @  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- O# W1 p8 w# w# W6 V- Z# R6 PSend 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.
& X: R( C9 e9 `2 ~$ i" h
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*/
( s/ h" y( H: O. R/ t, Omove into Q_process /*Single capacity*/

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

7 t, Q$ D* N# Jsend to P_B
end

1 u; g. X3 y  N' A  [) AP_B and P_C is similar
triangular 30,60,90 min
. v+ E1 w' ^! x1 Vu 60,30 min

in P_C, you need to send to die.
* H1 e% a) A+ P$ A; U8 v" R8 ]
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.
