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，
& A9 B/ ~8 M/ p, k1 x5 X6 p  w  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:
; o# S9 T. v0 L* Y% m. [  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 P1 X4 u7 w# {' `  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 w) }  p* ~$ L  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
: E  z* y7 p  |, pSend 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.
