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,6 l& W8 S4 C4 x- _( z
  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.
6 n3 X9 P, l) X4 q( Y, e# j( Y; c  Loads are processed by each operator for the following time:) W* ]' W# |# A# u
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.4 Y/ ]  p! D' D
  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.6 k$ L/ @  P  x: {( ?5 a- I, l
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.1 v  j: h0 ~6 i2 E
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.
