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，
4 D0 C+ r" t! S- T/ n9 d! F8 L, R  U% A  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:
/ L8 O5 |: M3 z! c4 D1 C1 r  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  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.
" O' K' e2 e. j* e* v! `  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
7 H1 p4 Z# {$ V1 U# tSend 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.
