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，
: S0 `: h- Q: A( b" B$ u- P4 L  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.
  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.
5 @( z0 u8 t- \2 X  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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
  b5 O; `  H0 ~0 r3 r5 `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
move into Q_wait /*Capacity is infinte*/
$ A1 r1 l1 \% F9 amove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
/ l& W/ f/ k3 l; [% \3 [' K& Q( T
send to P_B
' E7 h$ P& D  [8 O% c# Eend

P_B and P_C is similar
triangular 30,60,90 min
u 60,30 min
# \8 z$ @1 e3 t1 I

in P_C, you need to send to die.
/ q7 E$ [- f% Y2 u4 J2 @% }8 |2 \
Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
