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，
$ Y2 S- j5 w+ a7 u1 ?  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.
/ R' d! Y6 b) }2 f  C1 F; P  Loads are processed by each operator for the following time:
, I0 O: R' N0 r  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* C; t( F- ?2 }. N$ f  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.
( P# [& ^6 V+ P& q  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
0 u( q/ @7 K* e& T, E; E6 gSend 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
move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
) X9 E, R# I' B0 O
use R_A for n 60,10 min /*Resource A*/
# a) _4 J, Z1 `% V
2 a% L3 ^6 y: u; [* Usend to P_B
end

P_B and P_C is similar
triangular 30,60,90 min

in P_C, you need to send to die.
% {" H0 Q9 @" q) ~1 s
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.
