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,5 ?- N0 H1 w3 B( ~, H, |
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.

1 {) Q1 s9 h) P: r Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.

Worker_C does the job in a uniformly distributed time between 30 and 90 mins., z# T& Y. M# t
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.
