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，
' h9 X! }, D( w( m* O* ]5 ]  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.
% m  G  N' _" q* ^# \$ ]& v+ l  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.
$ P* K/ {* [' y1 m  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.
3 B+ n0 r  I3 Y! CSend 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*/
: B: Y$ l$ {4 g5 [move into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/

6 Y7 B8 V9 C2 G! rin 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.
