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，
4 _7 A  D1 K4 N- ]! W- t! C8 h  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.
. X/ Z! Z6 S  R5 ?  U: u+ D  @7 m  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.
2 o  `) L# t, Z: {6 J+ [0 w3 z  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.
/ i4 q( K3 j9 a2 w- l7 \  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
9 R& ?  y) G5 B5 D  ESend 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*/
8 I: ^( ]+ H# Q( b9 \  Q) Rmove into Q_process /*Single capacity*/

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

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