Validation of scheduling algorithms for aperiodic tasks in the real time systems

Mixture of periodic and aperiodic task sets is very often in the scheduling. This mixture is scheduled by the combination of the periodic and aperiodic tasks scheduling algorithms. Validation of these algorithms could be made by the developed visual software support. Timing properties of the scheduling algorithms are in opposition to the resource utilization and workload. Diagrams of the aperiodic response time, number of missed deadlines and resource utilization gives possibility for the mutual comparison of the tested algorithms. The validation is performed through the proposed criteria. Algorithms with the server tasks and bandwidth preservation give better results.
