| 摘 要： | 针对当前网格工作流调度算法中大多只考虑DAG结构的网格工作流、涉及QoS参数较少及将多QoS参数聚合成一个单目标函数进行优化调度的现状，提出了一种新颖的网格工作流调度算法。该算法基于表达结构丰富的AGWL语言建模网格工作流，且基于MOPSO算法所设计的带多QoS约束的多目标优化的网格工作流调度算法。通过与基于NSGA-Ⅱ算法的网格工作流调度算法比较，表明了该算法的有效性。

| Abstract: | Existing grid workflow scheduling algorithms commonly are suffered by one or several of the following drawbacks:Most only have considered the structure of the DAG grid workflow,have not enough considered the multidimentional QoS parameters and the multidimentional QoS parameters will be aggregated into a single objective function for optimal scheduling.The paper presents a novel grid workflow scheduling algorithm.The algorithm is based on the structure of the expression of a rich language AGWL grid workflow... |
