Quality of Service Estimation Model for Service Composition
The current work and existing problem of service composition are analyzed in this paper, and a new quality of service model which includes service time, service cost, reliability, maintainability, and satisfaction, is presented from accurate and practical view. The computation method of the quality of service model is studied too. Based on the quality of service model, the quality of service estimation problem for service composition is studied mainly, a kind of mathematical model for quality of service estimation of service composition is presented, and its characteristics and related works are analyzed, and its validity is validated through simulation experiment.
