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，
3 ?. b5 _8 J& z" }" n  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.
" ~3 B4 V. Y+ t' P2 ?  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.
& A- H- w3 [9 U* h  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.
# K6 F% T3 |8 P  `/ G# w! dSend 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*/
3 A# C& p$ B8 |: `  ^4 amove into Q_process /*Single capacity*/

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

in P_C, you need to send to die.

: `& v" l2 N- ]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.
