| Abstract | In the science area, workflow management systems are used for the purpose of managing collaborative researches of many organizations. While executing a workflow application, a workflow management system should decide the resource to assign each task and the order to execute the assigned tasks. The processing cost and the completion time can be very different depending on that schedule. Furthermore, users can ask for low processing cost or short completion time. However, satisfying those two requests at the same time is very difficult. Therefore, the existing workflow scheduling schemes try to find the optimal solution while setting bounds to one condition. These schemes can find some schedules that satisfy their own purposes. However, they cannot get the schedules satisfying various SLAs that vary depending on users, workflow applications, and so on. In this paper, we propose the adaptive workflow scheduling scheme based on the colored Petri-Net model which offers two selective workflow scheduling policies. The proposed scheme separates the scheduling phase and the execution phase, and distributes the actual remaining time in the execution phase as well as in the ratio of the processing time processing cost which is being decided for the scheduling phase. |
