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，
$ w9 U/ p/ {7 @& m" \7 ]  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:
. @+ V# w& X, w  q( q1 z4 a  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 w3 q, e! 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.
/ _/ N* R" H, ]3 K, J6 W  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
6 G. _9 Y+ Y3 K8 uSend 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.

7 T; T, }7 W6 I" Y  j5 ~# U* jThen You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
