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,
- b/ _. u6 ~/ I2 o7 g) ^" x  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.% L$ K- F/ ~4 U+ {4 d. k! I
  Loads are processed by each operator for the following time:+ u2 r9 q1 w- Q* d+ V( {( \
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.$ L$ a( V& m" Q; u
  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.7 j4 {" W) P' N& m! g+ N- f! P
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.& d1 \1 T; w8 }' L/ ~- {
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.0 h* ~0 h" Q% I* _( u# Q. F

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