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,: `/ g$ H5 K' N: O
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.7 H0 \1 P. T; Y* N
Loads are processed by each operator for the following time:' {" i+ [0 |3 q4 p
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
_+ t$ o) E8 T+ q3 G/ X+ X9 h- 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.
+ G" N$ c$ ]) N* k/ @( }* ? Worker_C does the job in a uniformly distributed time between 30 and 90 mins.7 u3 l: O- X; v, h4 Z& m1 `* _
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.+ n7 ?* Y& Z4 G8 _1 l3 l

问题:
