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，
  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.
/ K& w+ k5 e9 K8 B' ~9 S  Loads are processed by each operator for the following time:
' _# E. P) _  M9 G* A3 x- `# g; o  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
/ x. w0 [& K! D% y- |5 ?  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.
/ p6 _+ i$ `8 M1 p4 a* y, x* M4 w2 F4 ASend 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.
