Aperiodic Task Scheduling

In this chapter we present a variety of algorithms for scheduling real-time aperiodic tasksAperiodic task on a single machine environment. Each algorithm represents a solution for a particular scheduling problem, which is expressed through a set of assumptions on the task set and by an optimality criterion to be used on the schedule. The restrictions made on the task set are aimed at simplifying the algorithm in terms of time complexity. When no restrictions are applied on the application tasks, the complexity can be reduced by employing heuristic approaches, which do not guarantee to find the optimal solution to a problem but can still guarantee a feasible schedule in a wide range of situations.
