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,% I0 u  Z1 d; ]. [( a7 K" }
  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.

  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.

  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.6 P& k2 i# x& K  m/ W
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.
