Wang Meiyun · Jisuanji gongcheng · 2008
This paper analyzes the state of the art and existing problem of Quality of Service(QoS) and its estimation,and a reference matrix for QoS is given out.A new QoS model which includes service time,service cost,integrity,availability,and reputation is put forward from accurate and flexible view.In this model,a new method for QoS estimation is presented.This method which collects quality information from users is used to calculate the QoS using a kind of fuzzy method for QoS estimation based on the QoS requirement of users.Its correctness and feasibility is indicated through experimental analysis.
