Worst-case response time analysis is used for schedulability check in multi-task real-time systems. In general, tasks have fixed deadlines in the system. But this analysis using fixed deadlines may underutilize some specific systems. So new concepts of deadline description, and proper scheduling strategies are needed in such systems. In this paper, for a system where deadlines of tasks are shifting in task execution order, and we propose an effective scheduling strategy for the system.
