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,3 E" y* _# t+ y  I% q3 e
  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.
6 i% j4 }9 G! J/ z  Loads are processed by each operator for the following time:2 i0 k8 e$ \6 z0 P9 C% ~% s
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.& w6 Z( F. _5 m+ d
  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.
