• A Failure-aware Activity Scheduling Method for Web-Service Based Work ow Management

抄録

In a workflow management system, appropriate allocation of its activities greatly contributes to improvement of its efficiency. We have proposed OXTHAS, a load-balancing method of scheduling the activities in workflow management systems using Web services. The OXTHAS makes the activities be allocated to appropriate executors based on the estimation of their processing capacity using execution histories in workflow engines. In this paper, we propose a failure-aware re-scheduling method for the OXTHAS using process timeouts under the network and system failures. To allocate activities appropriately, the estimated processing capacity and timeout duration are re-calculated with considering the penalty for a failure when a process timeout occurs. We then evaluate the effectiveness of the proposed methods through simulations.
