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，
7 }" |- U# _& o" {  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:
$ S$ U9 e- Q' R% ?3 D6 a  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
9 t& x; l5 R7 @- Z! P. Q5 W  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.
' g/ m) p) S, \; I/ T' r$ W  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
, z8 ^4 v, @) ?8 Z% Vmove into Q_wait /*Capacity is infinte*/
1 N) a0 {1 i6 A# R: ]9 Bmove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
4 X) C1 o  V$ \; W6 I1 @7 Z
send to P_B
3 e. Z  R0 S# x; C- Wend

P_B and P_C is similar

in P_C, you need to send to die.

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