| 摘 要： | 提出了考虑具有不同输入速率和输出速率的任务队列的网络动态调度系统状态空间模型,描述了网络动态调度系统的清空型调度策略,并在此基础上给出了系统服务质量性能指标包括队列长度、总任务数量、系统吞吐量、响应时间等的分析算法. 数值计算表明,适当的调度策略可以使网络动态调度系统的响应时间处于受控的范围内,系统吞吐量处于稳定的状态.

| Abstract: | A state-space model based on discrete events was proposed to describe the network dynamic scheduling system.A number of heterogeneous jobs were concurrently taken into account.Upon describing the clearing policy of the network dynamic scheduling system,algorithms were developed for analysis of QoS(Quality of Services)performance parameters,which include queue length,total job number,the system's throughput,and response time of job request.Numerical calculations showed that the optimized scheduling policy could make the response time of the system within a controlled scope while the system's throughput was in a stable state. |
