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,) w$ x5 ?0 H7 A5 U9 Q7 \
  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.
, `" }" l, {% L9 s6 }) l" q  Loads are processed by each operator for the following time:, v5 u1 T6 m2 K2 H, b
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
9 e* H& N; o6 x- y  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.
- p: {6 w) A  q: q1 f  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
* X& a( C$ d4 x3 W9 oSend 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.% g" R6 I8 y7 @1 {" a
