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,& p0 L# y7 i5 l7 \6 Q/ B
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.
C' l5 V2 Z( \; P* }8 a& p Loads are processed by each operator for the following time:1 o* F, i: F3 I/ Y- a+ t6 b7 e
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
8 c7 q2 k2 r. D8 {7 L1 y( S; d 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.
( }1 L# u8 h: v, q# @$ k Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
* n. {" ?) m6 V$ DSend 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.
