Qos Performance Analysis for Grid Services Dynamic Scheduling System

State space model based on the discrete events is given to describe the grid services dynamic scheduling system which processes a number of heterogeneous jobs concurrently. Algorithm of QoS(Quality of Services) performance parameters analysis, such as queue length, total job numbers, throughput of the system, response time of job request, are developed. Calculation shows that suitable scheduling policy can make the response time of the system within a controlled scope and the system throughput within a stable state.
