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,# _1 m3 [+ c7 R5 L
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 \- Q9 d3 W7 ?6 n m( ?5 P
Loads are processed by each operator for the following time: C" e0 P4 ~4 ^- z3 R8 a+ ~# Z6 Z
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.: [0 Z+ b+ h9 N& Q1 |# _0 ~
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.) O" H8 o( r8 R$ c) J, a) ^
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.) F4 {( h8 Q* z# ^/ i+ A# T" F
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.
