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,; L8 c7 n: N  ?5 P& E' P; 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.
$ O; X: _: O  o  I' \7 b& @+ C+ t% J  Loads are processed by each operator for the following time:
. j( V* o# Y! G0 B7 ?( S$ `( _7 V  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.3 r4 S) N: @+ N' d) c
  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.
: T+ ^: I2 N) d' Z4 x3 E. B  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.# d& i2 Z6 t% J( J" s8 U
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.

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