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.
# @5 h2 i3 Z: ~8 ^  Loads are processed by each operator for the following time:
: m; p! J  V9 m3 p: _6 B5 `9 }  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 d% z7 t) ?; O! h  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.
3 U% W& j7 j0 y( Q6 F( ]" F& I  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.

begin P_A arriving
5 v, @: Q: j! r+ @move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
" I- J9 T. a/ D# n
use R_A for n 60,10 min /*Resource A*/

send to P_B
end

P_B and P_C is similar
triangular 30,60,90 min
u 60,30 min
0 d$ r/ T. }; U" W2 v& t

in P_C, you need to send to die.
' s8 G- B: t+ t) Q% f) X+ U: q% m
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.
