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,* P% G. g' b4 \' T7 v! }4 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.
0 d; j" q: W- P6 e Loads are processed by each operator for the following time:
7 n( d8 ]# N6 L P: K0 I Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
j: c' J( }* v2 B, ^7 n 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., W4 ^; S( D/ r& H+ c, m. y; O7 }# X
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.1 m& b; n9 u8 H
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.5 N/ a( z# n5 ?
