To guarantee user specific QoS requirements, it is necessary to represent and calculate the user QoS preference information.A method of ordering vector representation and calculation for QoS preference is put forward.This method firstly transformed QoS attributes order sequence to the form of order vector.Afterwards, the optimization model is applied to calculate the weights of QoS attribute vector.Finally, the QoS vector is utilized to determine the optimal candidancy services.The method could transfer the user QoS preference information to the quantification computation form, and a concrete example confirms its validity.
