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,
, \7 u$ s$ e& J& S  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.
( T( `  A5 H- N) X1 D& k  Loads are processed by each operator for the following time:2 c! G8 S$ Z* ^6 v+ R- i
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
$ V  x! y% b+ V$ g* O1 O  h- ~( `  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.4 K: @0 |4 e& z+ o
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.0 M6 S3 H9 X/ n/ P- t& _5 @
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./ ]3 q: T# c  x3 t2 `" w

不胜感激!

Remember to turn off the animation before you run your model.
