Abstract: QoS parameters is matched one by one in current grid resource scheduling，the trouble of this task only offers a qualitative concept about QoS requirement.In this paper，a new approach is presented which empowered QoS parameters is matched by qualitative concept that tasks offer.Firstly，QoS parameters based on the cloud model are analyzed，and induce model of QoS is proposed，by this，QoS parameters can be induced to a qualitative concept.Secondly，the architecture of QoS transform is presented.At last，the optimize scheduling algorithm is described based on the model.Finally the simulations are performed to compare the performance of optimize scheduling algorithm with that of the time minimisation and cost minimisation.The experiments show that the optimize scheduling algorithm is efficient on throughput and system resource utilization ratio within grid computing environments.
