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，
; J: U. s3 v. ^7 y4 a( 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:
: h8 K0 g: G! {! u4 |+ _  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
# ]/ v# S$ w6 E& |4 ^4 H1 L2 {  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.

in P_C, you need to send to die.
5 G- V% t5 x% p( G* ^2 R
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.
