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，
* `* \3 B6 Q2 Q, @  k( D$ }5 C  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.
& p' u- x" x+ r! ~/ L) A; F  Loads are processed by each operator for the following time:
# q. X' L+ I+ m+ F! g+ M5 D7 J& |5 w( ?" p  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.
* t3 s2 @6 e  X4 Q2 S: a  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
* ]2 T/ x; ^: G2 BSend 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
, D) D# m8 _, A5 u: L# ymove into Q_wait /*Capacity is infinte*/
4 n) U! u0 X( b9 smove into Q_process /*Single capacity*/

. f3 ]2 A4 Y; }# t) k8 w9 _" }use R_A for n 60,10 min /*Resource A*/

9 d0 T; S+ w( W( n7 u% ~send to P_B
end

P_B and P_C is similar

& Q9 u4 H& R% u  Hu 60,30 min


in 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.

Remember to turn off the animation before you run your model.
