A generic approach for the certified schedulability analysis of software systems

Xiaojie Guo, Lionel Rieg, Paolo Torrini
2021 2021 IEEE 27th International Conference on Embedded and Real-Time Computing Systems and Applications (RTCSA)  
We describe a case study for the FPP and EDF policies providing end-to-end assurance by connecting the schedulability analysis tool Prosa and the real-time OS kernel RT-CertiKOS, both using the Coq proof  ...  In particular, schedulability analysis is both essential and difficult to get right. Formal methods can help as they are a powerful tool for ensuring properties with the highest assurance level.  ...  Acknowledgments: We would like to thank Sophie Quinton for insightful discussions and her comments and help with writing the paper.  ...

H^2CM-based holonic modeling of a gas pipeline [article]

Carlos Indriago, Latéfa Ghomri, Olivier Cardin
2019 arXiv   pre-print
In case of stable and perfectly known demand, scheduling techniques can be used, but in other cases , calculation times are incompatible with an industrial application.  ...  A gas pipeline is a relatively simple physical system, but the optimality of the control is difficult to achieve.  ...  To overcome this problem, hybrid Petri nets consider a state as a marking with a continuous and a discrete part. They provide very compact and readable models very useful for engineers.  ...

A Generalized Digraph Model for Expressing Dependencies

Pascal Fradet, Xiaojie Guo, Jean-François Monin, Sophie Quinton
2018 Proceedings of the 26th International Conference on Real-Time Networks and Systems - RTNS '18  
We propose here a task model that generalizes the digraph model and its corresponding analysis for fixed-priority scheduling with limited preemption.  ...  Our objective (still in progress) is to formally certify the analysis for that general model such that the correctness proof of a more specific (standard or novel) analysis boils down to specifying and  ...  We would like to thank Maxime Lesourd for insightful discussions.  ...
