Scheduling Complex Cyber-Physical Systems with Mixed-Criticality Components
Systems, 2023 Two emerging trends for designing a complex, cyber-physical systems are the component-based and mixed-criticality (MC) approaches. A component-based approach independently develops individual components and subsequently integrates them to reduce system ...

Mapping AADL models to a repository of multiple schedulability analysis techniques [PDF]
, 2013 To fill the gap between the modeling of real-time systems and the scheduling analysis, we propose a framework that supports seamlessly the two aspects: 1) modeling a system using a methodology, in our case study, the Architecture Analysis and Design ...

Stochastic Analysis of Cyclic Schedules [PDF]
Operations Research, 1993 A cyclic schedule is a sequence of tasks on a set of machines that is repeated indefinitely. We model cyclic schedules as Markov chains and use ergodic theory to analyze and improve the performance of cyclic schedules in environments with machine breakdowns, yield losses, and other sources of variability.

Utilization Bound Scheduling Analysis for Nonpreemptive Uniprocessor Architecture Using UML-RT
Modelling and Simulation in Engineering, 2014 The key for adopting the utilization-based schedulability test is to derive the utilization bound. Given the computation times, this paper proposes two utilization bound algorithms to derive interrelease times for nonpreemptive periodic tasks, using a ...
