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,, J! Z1 V! \* _& E1 j, Q
  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.
  x$ M: w  V+ R: `$ k. C( ?" X  M  Loads are processed by each operator for the following time:0 @6 h9 A  Y8 g
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.5 H6 J# f1 _9 V
  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.
* r" S7 L+ D3 X  Worker_C does the job in a uniformly distributed time between 30 and 90 mins." s: r! R2 \2 M% p: W* j; g. o' M
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.
