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# G" e$ W/ ?' T5 E4 p" G' }- f
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.
9 ]5 c* X: T. ^0 ]8 Z Loads are processed by each operator for the following time:7 L. m p; E! m5 o z) }: A% ~
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
: K- E! L+ s% Z 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.
3 Q4 q& w% Y1 q% g/ K Worker_C does the job in a uniformly distributed time between 30 and 90 mins. s6 c# n @# m* W
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.
