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,
* a  @: _% n" z7 `3 F4 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.
' s4 K- W' {+ ]4 a& j" C  Loads are processed by each operator for the following time:5 W* W/ Y1 G& E7 y" V' W1 b
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.1 H. S% B, I! b+ {; R1 s3 Y
  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.
4 x( Z: S- F% X2 ]/ z; x  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- r& I5 J8 ~5 Z+ p+ @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.  _0 ?0 E) b+ F$ R7 A. C/ B/ _

  \2 _, w3 t- X问题:

不胜感激!

in P_C, you need to send to die.
