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.
, h& {7 z& [1 b) L/ v" e! \  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.
4 o. c7 @9 w5 I, \+ }' w7 A: y  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.
# X  d& \( R" q  p" f6 v  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：
% b  x4 x4 @  `$ gAfter running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
$ @/ `! Q& N" R1 I) s% pmove into Q_wait /*Capacity is infinte*/
/ c, g6 [5 ]4 d( a/ Kmove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
% y+ {$ T) O& O+ y9 e. G
send to P_B
. b+ g$ G& Z( x! gend

P_B and P_C is similar
! [$ o" [- @# Z2 I0 g$ m" Ptriangular 30,60,90 min
& f0 }" B& K$ r$ iu 60,30 min


in P_C, you need to send to die.
6 Y/ @+ u9 s3 i3 c0 K* }5 g
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.
