工作流系统中的动态任务调度
Dynamic Task Scheduling Method for Workflow Management
【摘要】 在分析工作流中任务调度特点的基础上 ,提出一种基于资源约束的动态任务调度算法。该算法一方面保证了任务调度满足资源的约束 ,另一方面实现了任务难度与任务承担者能力的平衡。基于该算法的任务调度策略不仅可以适应动态环境的要求 ,而且增强了系统的并行处理能力
【Abstract】 Based on analyzing the characteristics of task scheduling problems in workflow, a resource-constraints based dynamic task scheduling algorithm is developed in the paper. On one hand, this algorithm can ensure the satisfaction of resource constraints for task and on the other hand, the balance between difficulty degree of the task and capability of the performers is achieved. Based on this algorithm, the dynamic task scheduling method can not only be fit for the requirement of dynamic environment but also enhance the parellel processing ability of the system.
