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.
" w3 b9 r$ Z" W: F- m9 I  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.
+ j  @: b) e3 B! N* [  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.

, ^5 p3 Z9 S( ]* T' e% V+ n) R" @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*/
! x" \! p0 T0 O2 }" fmove into Q_process /*Single capacity*/
, j) l8 R! }$ \1 S! l
use R_A for n 60,10 min /*Resource A*/

( I  F+ u: `0 V1 Z' [, }* W1 dsend to P_B
end

P_B and P_C is similar
1 G8 l2 |' U; G- U- f1 Dtriangular 30,60,90 min
5 P5 ~' W) l+ I% D* Gu 60,30 min
$ U4 a7 i1 y, m! f5 A2 k5 O- @8 K1 O

in P_C, you need to send to die.
3 Z* m) @- ~1 D5 _+ u
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.
