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 D- i+ i7 K5 i  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.
) F. v( E$ \! C5 F/ C' p  Loads are processed by each operator for the following time:( w+ A6 W  k5 x$ x! w$ k4 z
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
, M) ?2 p; M, |  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.
, d% ^0 T5 @7 w( U0 _% I* j1 q  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ O1 B7 |. a3 E7 n5 @7 f, G% W8 }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.
