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，
2 k( m/ K, J8 G% f5 ~+ \/ _  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:
/ A  f# o9 u& l9 _2 `5 p5 o  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  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.
0 @+ J# M0 b4 ]4 f" o  n1 f) G  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ Y1 M5 f: ~  J' k/ GSend 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*/
move into Q_process /*Single capacity*/

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

send to P_B
end
8 E% E0 P4 L" G2 o
P_B and P_C is similar

$ ?6 d% J/ J- c' lin 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.
