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,9 i& \/ }! P3 V, 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.
/ A) c  l, ?, [" h* b" j; R  Loads are processed by each operator for the following time:6 B) B3 d  z  `* e! N7 Y
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.: g0 k8 R; d+ X- P
  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.2 C5 p8 p. [0 \" e3 K
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.  v( e; i8 G8 p7 c; Z+ q
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.
