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，
  @: S- r3 t9 j0 k' ~8 I  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.
0 a' Z2 }' M7 y7 i  Loads are processed by each operator for the following time:
9 n) S3 N' _7 _* L+ C( F  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 P: u! g4 N5 Z  O$ g  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.
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*/
1 h1 J7 n, S4 a5 h  e! ?move into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
7 ?* C+ \) J2 _/ l6 x
8 l5 X* m3 o8 p4 Ysend to P_B
end

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