A flexible control mechanism for managing interrelated/interdependent tasks successively

We propose a framework to manage interrelated tasks concurrently and successively, and address the issues of event handling and task scheduling: the event handler organizes interrelated tasks from a static point of view, and the task scheduler controls them on the basis of the dynamic behavior properties. In order to design our flexible control mechanism, we introduce the state transition graph and AND-OR graph in the event handler, whereas in the task scheduler the timestamp ordering method is applied to. Additionally, we describe the failure handling, concerning the cooperation between the event handler and task scheduler
