摘　　要：针对单优先级数据分发任务调度算法存在的缺陷,依据网格任务分发服务质量(QoS)效益函数理论,运用加权法将网格系统的性能指标转化为加权效益和函数,将加权效益和函数作为启发式函数,设计了一种基于效益函数的任务调度算法对数据分发任务进行调度,并进行仿真实验。结果表明,该算法弥补了只考虑单优先级数据分发任务调度算法的缺陷,具有一定的实用性。Considering the fault of simple priority Data distribution assignment dispatching algorithm, appling grid assignment dispatching quality of service（QoS） effectiveness function theory, the method of weighting is first used to transform the performance target of grid system to weighting effectiveness sum function. And, regarding it as a heuristic function, the paper designs an assignment dispatching algorithm to dispatch the information distribution assignment. The simulation results show that the algorithm remedys the fault of simple priority information distribution assignment dispatching algorithm, being of a certain utility.
