Treatment Strategies of QoS Preference Information Based on Service on Demand

To meet the requirement of service on demand,it is needed to build concrete strategies and methods to deal with Quality of Service(QoS) preference information of user.The paper goes deep into description of QoS preference information and presents description way of QoS preference information based on AHP(analytic hierarchy process) judgment matrix.The description way converts QoS preference into AHP matrix with scaled number and utilizes eigenvector method to calculate the weight vector,thus a numerical representation is provided for QoS preference.At the same time,a solution strategy is put forward based on QoS preference.The example of number analysis indicates that the QoS preference treatment strategies in this paper are feasible.
