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- g2 W) A- ^  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.
  Loads are processed by each operator for the following time:
% P! I, C( G/ `  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
: D! s% j$ f6 j+ b# ?  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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 f8 V! c: P4 s- M. z* d$ X  BSend 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.

in P_C, you need to send to die.

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