In this thesis, the work focuses on Grid Workflow modeling, dynamic optimizing and dynamic scheduling.
本文重点研究网格工作流建模、动态优化和动态调度。
Since the time order and the data dependence exist in the grid workflow, the workflow scheduling in grid is a complete NP-hard.
由于网格工作流任务之间存在时序和数据依赖等关系，使得网格环境中工作流的调度问题成为一个NP完全问题。
TP meets the deadline of the workflow while paying less than the current scheduling algorithm. 3 Construct grid workflow schedule system prototype.
TP算法能确保在截止期限内完成工作流的所有任务，并且在执行成本上比现行算法更优。3构建网格工作流调度系统的系统原型。
