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，
, }8 _6 X& V/ K) L, Q; H4 R  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.
( f* J+ G' N9 T  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.
  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.
4 W$ ]" R4 ~6 k" {2 Y& M  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- }0 \. H. V) T  Y' O0 V1 LSend 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.
% I7 P' Y- |2 r
问题：
After 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
. c& c2 q0 L6 Umove into Q_wait /*Capacity is infinte*/
. u$ M% B+ E; Y2 @5 e, X( V: |move into Q_process /*Single capacity*/
4 {  U( x  I. J- z+ c
use R_A for n 60,10 min /*Resource A*/
! w; A% r$ j8 U0 X' j9 ]
send to P_B
end
7 P2 M: l9 P7 L8 m1 w9 [
P_B and P_C is similar
triangular 30,60,90 min
u 60,30 min
) u& Z: i2 N3 w7 C5 F& W

/ D# L4 O8 F8 kin 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.


+ Q3 E4 _: ?$ s6 ~+ \8 P8 eRemember to turn off the animation before you run your model.
