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，
5 a4 b2 J3 w# I7 ?( L6 Z  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:
# t- ^& m' {4 L9 S# T; A  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
) D. M  g( X. b! |5 Y; e# u5 Q  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) J2 s$ y7 o% Y8 ?, B  ySend 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_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
) ]2 X. h/ M9 x

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.

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