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,
, U: v! S, ~4 e6 J# [ 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.0 E4 d& o4 }, S5 a% K
Loads are processed by each operator for the following time:; m$ R, r& O! X! U/ k9 }0 ]' H
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.+ l, o7 P/ R* t
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.! Q! r2 G( N: [
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.& ^8 @2 z: k) i4 N r8 l
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.8 ~/ j6 F6 o/ q9 \$ Z. X- L

问题:
