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,! V" V, A8 w X, P0 ]$ y4 v/ |
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.
; g% n8 p! g( [) _! {9 L# [ Loads are processed by each operator for the following time:
|9 |0 z- G( ` Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.; R2 h4 L! ]# I. U, h6 X# ]
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.) o8 I+ n3 R! L' @9 m& k
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.9 M$ t9 J* y$ e9 V% y" [$ O
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.
